Safety: Warnings and Cautions

Before using the Pro 500 Anti-Gravity Treadmill, please read this manual. As a physical therapist, trainer,

or clinician (the operator of the product), you must understand the safety features and user interface. We

want you and your clients or patients (the users of the product) to have a safe and enjoyable exercise

experience.

DANGER: Imminently hazardous situation to be avoided that will result in serious

injury or death.

• Do not modify the Anti-Gravity Treadmill electrical plug. The treadmill comes equipped with a twist

lock plug of correct configuration and capacity. If the provided plug will not fit in the outlet, have a

proper outlet installed by a qualified electrician.

• Do not use any electrical adapters. To do so could result in an electrical shock hazard.

• Consult a qualified electrician before using any extension cords. Long extension cords may cause a

voltage drop to the Anti-Gravity Treadmill, which may cause it to operate improperly. AlterG provides

a 15ft cord.

• Do not operate the Anti-Gravity Treadmill in wet or damp environments.

• Do not operate the heart rate monitor transmitter in conjunction with an electrical heart pacemaker or

similar device. The transmitter may cause electrical disturbances which can interfere with pacemaker

function.

• Always unplug the Anti-Gravity Treadmill before cleaning or servicing.

• Do not soak any part of the Anti-Gravity Treadmill with liquid during cleaning; use a sprayer or damp

cloth. Keep all liquids away from electric components. Always unplug the Anti-Gravity Treadmill

before cleaning and maintenance.

• Service should be performed by an authorized AlterG technician. Service by non-authorized AlterG

technicians will void the warranty. Contact AlterG before you or an electrician attempt any

maintenance.

• Do not place any liquids on any part of the Anti-Gravity Treadmill (except in the water bottle baskets),

including the Anti-Gravity Treadmill running surface.

• Always keep the running surface clean and dry.

• Do not unplug or alter any of the internal wiring on the Anti-Gravity Treadmill after installation.

WARNING: Potentially hazardous situation to be avoided that could result in serious

injury or death.

• Users must consult with their physicians and obtain a medical exam before beginning any exercise

program. This is particularly true if users have any of the following: history of heart disease, high

blood pressure, diabetes, chronic respiratory disease, elevated cholesterol, if they smoke cigarettes,

are currently inactive, are obese, or have any other chronic disease or physical impairment.

• Users must stop exercising immediately and consult a physician if they feel faint, dizzy, experience

chest pains, nausea or any other abnormal symptoms while using the Anti-Gravity Treadmill.

CAUTION: Potentially hazardous situation to be avoided that may results in minor or

moderate injury.

• Always use the emergency safety lanyard supplied with the Anti-Gravity Treadmill. It should be

clipped to the user’s article of clothing while exercising. This is an important feature in case the user

falls during a workout session.

D000449-00 Rev. D 9-July-2021

• The oval support frame must be pushed all the way into the height adjusters located at the front and

the rear of the Anti-Gravity Treadmill and the safety latches must be closed and secured before

beginning operation of the Anti-Gravity Treadmill. Failure to do so may allow the oval support frame to

dislodge during operation, resulting in possible injury to the user.

• Read, understand and test the emergency stop procedure before use.

• Never leave children unsupervised around the Anti-Gravity Treadmill.

• Safety and effectiveness in pregnant women have not been established. Pregnant women or women

who may be pregnant should consult their physician before using the Anti-Gravity Treadmill.

• The Anti-Gravity Treadmill must be used under the supervision of a properly trained operator. At no

time should a user of the Anti-Gravity Treadmill exercise without appropriate supervision; even if

having been previously trained in the proper operation of the device.

• Set up and operate the Anti-Gravity Treadmill on a solid, level surface.

• Do not wear loose or dangling clothing while using the Anti-Gravity Treadmill. Do not store anything

(like shorts) inside the Anti-Gravity Treadmill enclosure.

• Prior to beginning a workout session, check to make sure there is no debris inside the Anti-Gravity

Treadmill.

• There are screened air vents at the front corners of the enclosure; check to make sure there are no

towels or other items near the screens which could get sucked in or block air movement.

• Keep hands away from the enclosure and frame structure during inflation to avoid pinching.

• Keep hands away from all moving parts.

• Do not use the Pro 500 Anti-Gravity Treadmill if the user’s weight is less than 85lbs (39kg) or greater

than 400lbs (182kg).

• Care should be taken when the user enters and exits the Anti-Gravity Treadmill. Users should never

enter the Anti-Gravity Treadmill while the treadmill surface is moving. Ensure that the emergency stop

safety magnet is attached to the treadmill so that the treadmill belt is locked and will not move when

the user steps on the surface. Make sure the user holds onto the oval support frame or handrails

whenever practical to support their body.

• Make sure that the user is fully zipped into the enclosure before beginning the workout session and

that the oval support frame is adjusted at the correct height and locked in place.

• Make sure the user wears proper athletic shoes, such as those with rubber or high-traction soles. Do

not allow shoes with heels or leather soles. Make sure no stones or sharp objects are embedded in

the soles of the shoes.

• As with any treadmill workout, make sure the user includes a cool-down phase at the end of the

user’s workout session. Make sure they return to full body weight and exercise moderately before

stopping. Avoid abruptly ending or pausing the workout session while the user is at reduced body

weight or at high speed.

• The safety and integrity of the Anti-Gravity Treadmill can only be maintained when the Anti-Gravity

Treadmill is regularly examined for damage and wear and is properly repaired. It is the sole

responsibility of the user/owner or facility operator to ensure that regular maintenance is performed.

Worn or damaged components must be replaced immediately, and the Anti-Gravity Treadmill

removed from service until the repair is made. Only manufacturer supplied or approved components

should be used to maintain and repair the Anti-Gravity Treadmill.

D000449-00 Rev. D 9-July-2021

Introduction

Consulting a Physician

Anyone considering an exercise program or an increase in activity should consult a physician. It is highly

recommended that users follow the guidance of their physician before and during an exercise program or

any other increase in physical activity if they:

• Have heart disease, high blood pressure, diabetes, chronic respiratory disease, or elevated

cholesterol

• Smoke cigarettes

• Are currently inactive, are obese, or have any other chronic disease or physical impairment, or if there

is a history of such disease in their family

The Importance of Warming Up and Cooling Down

It is important that users gradually warm up, cool down, and incorporate a series of stretches prior to and

at the end of each work out. Stretching encourages the necessary flexibility to help prevent sore muscles

and injury during daily activities.

Do not abruptly end the workout session on the Pro 500 Anti-Gravity Treadmill. The user’s full body

weight should be restored slowly and should include a few minutes of walking at full body weight and low

intensity before stopping the workout session.

D000449-00 Rev. D 9-July-2021

Setup and Installation

The Pro 500 Anti-Gravity Treadmill will be installed by an AlterG qualified technician after delivery. Please

make sure that you inspect the Anti-Gravity Treadmill upon delivery for any damage that may have occurred

during transportation. Take photographs and report any damage immediately to the shipping company and

AlterG. When you sign for the shipment of your Anti-Gravity Treadmill, you are taking responsibility for any

damage that may occur before installation.

Electrical Requirements

The recommended electrical power connection for the Pro 500 Anti-Gravity Treadmill is a dedicated 30

ampere, 220VAC @ 50/60 Hz circuit with ground. The plug supplied with the Anti-Gravity Treadmill is

designated by the NEMA configuration system as L6 30P

. The corresponding receptacle for the plug is a

NEMA L6 30P

International systems are shipped with a US plug on the power cord. An appropriate plug for the country

and facility in question should be wired as follows:

Blue Conductor: Neutral

Brown Conductor: Line

Green/Yellow Conductor: Ground

Grounding Requirements

The Pro 500 Anti-Gravity Treadmill must be grounded electrically. If there is an electrical malfunction,

grounding provides a path of least resistance for electric current to reduce the risk of electric shock. The

Anti-Gravity Treadmill power cord includes a grounded plug. This plug must be plugged into an appropriate

receptacle (NEMA L6 30P) that is properly installed and grounded in accordance with the current National

Electrical Code as well as all local codes and ordinances. If you are at all unsure of these requirements,

contact AlterG or a qualified electrician.

Location Requirements

The Pro 500 Anti-Gravity Treadmill measures 4ft (1.2m) x 8ft (2.4m) and weighs almost 1100lbs (499kg). It

needs to be placed on a structurally sound surface. If it is used above ground level, it is advisable to place

it near the corner of the room or where the floor will be strongest to ensure maximum support during high-

speed, high-impact use. The surface should be level to ensure minimal flexing of the Anti-Gravity Treadmill

frame. Do not place the Anti-Gravity Treadmill directly on thick carpeting because it may interfere with air-

valves located on the underside of the treadmill. The Anti-Gravity Treadmill needs to be within 12ft (3.7m)

(from the front of the treadmill) of the proper electrical outlet. Check with a qualified electrician or AlterG if

you plan on extending the cord in any way. Make sure you leave at least 24” (0.6m) on either side of the

treadmill to allow the enclosure to expand during inflation. Allow at least 40” (1m) behind the treadmill to

accommodate a user getting in and out safely.

We recommend an area at least 12ft (3.7m) long by 8ft (2.4m) wide to provide adequate space for operation

and user access. Also check ceiling height to ensure that users will not hit their heads on the ceiling while

running. The Anti-Gravity Treadmill surface is 15” (0.38m) off the floor when level and can be higher when

the subject is running on a grade. An 8ft (2.4m) ceiling may be too low for taller users.

Transporting Your Anti-Gravity Treadmill

Contact AlterG if you plan on moving your Anti-Gravity Treadmill. Damage sustained by improperly

moving the Anti-Gravity Treadmill will not be covered by your warranty.

D000449-00 Rev. D 9-July-2021

Operation

Powering On the Anti-Gravity Treadmill

1. The main power switch is located at the front of the

Anti-Gravity Treadmill. Switch it on to start the

system.

2. To boot up the software and turn on the touchscreen

display, press the power button located in back of

the console. As the software loads, avoid touching

the screen because it may interfere with the boot-up

process.

Note: Do not allow the user to stand on the Anti-

Gravity Treadmill belt during boot-up. If the user

inadvertently puts weight on the belt during boot-up,

an error message is displayed. Have the user stand

in a wide stance off the running surface to avoid this

problem.

3. When you see the Welcome screen, you are ready

to begin the workout session.

Note: If you have not read this manual, it is

recommended that you QUIT now or seek

appropriate instruction from a qualified operator. By

tapping START SESSION, you acknowledge that

you have read and understand this manual.

Securing the User in the Anti-Gravity Treadmill

The procedures in this section describe:

• Putting on the shorts

• Stepping into the Anti-Gravity Treadmill

• Zipping into the enclosure

• Installs the oval support frame

• Attaching the safety lanyard

D000449-00 Rev. D 9-July-2021

Putting on the Shorts

Your Anti-Gravity Treadmill comes with customized neoprene compression

shorts that ensure an airtight seal between the user’s body and the lifting

enclosure of the treadmill. It is recommended that the user put the shorts on

before stepping into the treadmill.

Have the user select a size that is snug but not uncomfortable and make certain

the tag is at the user’s back and on the inside of the shorts. For a comfortable fit

and to prevent bunching, it is recommended that the user wear a pair of running

shorts or tights under the shorts.

Stepping into the Anti-Gravity Treadmill

CAUTION: Before the user steps into the Anti-Gravity Treadmill running surface, ensure

that the safety magnet is in place on the console. If the safety magnet is not in place, the

treadmill assumes there is a safety problem and disengages the running surface, allowing

it to freewheel. This may present a slip hazard should the user step on the movable

surface.

The user enters from the back and steps into the opening in

the enclosure.

It is fine to step on the enclosure, but make sure that no

rocks or sharp objects are embedded in the soles of the

user’s shoes that could mar or damage the enclosure.

Installing the Oval Support Frame

1. The user faces forward and grabs both sides of the oval

support frame.

2. The user lifts the frame up until it is at waist level and

horizontal.

D000449-00 Rev. D 9-July-2021

3. Use the numbers on the height adjusters as a reference

and to ensure alignment between front, back and sides

of the support frame. It is particularly important that the

frame be level side-to-side.

4. Set the support frame at a height that places the zipper

at the user’s iliac crest (the top, outer edge of the pelvic

bone felt just below waist level). For additional trunk

support, the frame can be set higher.

5. With the support frame at the correct height, push it into

the slots of the height adjusters in the front and rear of

the Anti-Gravity Treadmill. Make sure it is at the same

height on both right and left sides.

6. Push the frame forward until it is fully engaged in the

adjustment slots and contacts the ends of the slots. The

rear of the frame can be placed up to 2 slots higher or

lower than the front.

7. Verify that the rear pins of the support frame are all the

way forward in the slots of the height adjusters and that

the frame is level on the right and left sides. The frame

should be in this position for the remainder of the

workout session.

D000449-00 Rev. D 9-July-2021

8. Close the safety latches located on the 2 front height

adjusters. Press the latches down all the way and secure

them with the spring-loaded safety pins.

CAUTION: Never operate the Anti-Gravity

Treadmill without the safety latches closed and locked in

place. This is an essential safety item that prevents the

oval support frame from inadvertently disengaging from

the height adjusters during exercise.

Never attempt to move the frame while the enclosure is

inflating or when it is fully inflated. If the enclosure needs

to be repositioned while the user is exercising, stop the

session. You can then change the height of the frame.

Zipping into the Enclosure

When the oval support frame is in place, the user zips into

the Anti-Gravity Treadmill. The zipper should be started at

the front and center of the body and zipped counter-

clockwise all the way around until it returns to overlap in the

front. Make sure that the zipper is completely closed.

When the user is in the Anti-Gravity Treadmill, the seal is

completed by zipping the shorts and the enclosure together.

The zipper provides a means of quickly attaching and

detaching the user from the enclosure, simplifies hygiene,

and provides a custom fit for users of all sizes.

Attaching the Safety Lanyard

Always use the magnetic safety lanyard supplied with the Anti-Gravity Treadmill. If you lose the safety

magnet, order a replacement from AlterG. As a precaution, the treadmill will not operate without the

safety magnet directly over the Emergency Stop label.

Operator or User Action Screen

1. Clip one end of the lanyard to the user’s shirt at waist level.

D000449-00 Rev. D 9-July-2021

Operator or User Action Screen

2. Place the lanyard safety magnet directly over the circular stud on

the console labeled “Emergency Stop”; otherwise, the Anti-

Gravity Treadmill will not operate.

CAUTION: Never attempt to defeat this critical safety

feature by clipping the lanyard to the enclosure, structure of the

Anti-Gravity Treadmill, or anywhere else other than to the user’s

shirt.

Should the user fall while exercising, the magnet is pulled off the

console and power to the treadmill is cut; air pressure is

released; the treadmill running surface disengages from its drive

and can move freely.

3. You are ready to start the software and operate the Anti-Gravity

Treadmill. Continue to “Starting and Completing a Workout

Session”.

D000449-00 Rev. D 9-July-2021

Starting and Completing a Workout Session

The procedures in this section describe:

• Starting a workout session

• Using the touchscreen features and controls

• Adjusting Anti-Gravity Treadmill speed and direction

• Adjusting pain levels

• Displaying gait analytics

• Starting live video monitoring

• Using AlterG Assistant

Starting a Workout Session

Operator or User Action Screen

1. Tap START SESSION on the Welcome screen.

2. Follow the instructions in the Before You Begin

screen, and then tap START CALIBRATION.

The calibration routine provides critical information

the Anti-Gravity Treadmill needs for accurate

control of body weight during exercise.

Note: For an accurate calibration, it is critical that

the user’s full body weight be applied to the belt

surface. Holding onto any other part of the

treadmill, for example, resting an arm on the top of

the enclosure while the treadmill calibrates, will

result in an erroneous calibration and inaccurate

body weight adjustment during exercise. It is

recommended that the user hold their arms out to

their sides or crossed on their chest, away from any

structures, during the calibration procedure.

When calibration is complete, the percentage of the

user’s body weight that can be unweighted is

displayed.

3. Tap START SESSION. The workout session

begins.

Adjusting Anti-Gravity Treadmill Speed and Direction

Treadmill speed is expressed as a numerical value in miles per hour (mph) or kilometers per hour (km/h).

Increase or decrease the speed using the arrow controls. Speed is adjusted in 0.1 mph (or 0.1 km/h)

increments. The exact function of the speed controls depends on the direction of movement of the

treadmill surface.

Walk or run forward adjustment:

1. Tap the up-arrow speed control until the treadmill surface begins to move and you are forced to walk

in a forward direction. The speed reading is displayed as a positive number.

2. Tap the arrow speed controls to increase or decrease the speed.

3. If you decrease speed all the way to 0, the treadmill surface stops.

Walk backwards adjustment:

1. Tap the down arrow speed control until the treadmill surface begins to move and you are forced to

walk in a backwards direction. The speed reading is displayed as a negative number

Note: If you want to reverse the treadmill direction while you are walking forward, first set the speed

to 0 mph (or 0 km/h, or 0 m/sec) and wait for the treadmill to come to a complete stop. Tap the down

arrow speed control until the treadmill surface begins to move in a reverse direction, forcing you to

walk backwards.

2. Continue to tap the down arrow speed control to increase the speed.

3. To slow the backwards walking speed, tap the up-arrow speed control until it reaches 0 mph and

treadmill stops.

General Recommendation for Speed vs. Intensity

Speed, mph Speed, km/h Exercise Intensity

1 to 3 1.6 to 4.8 Walk

3 to 8 4.8 to 12.9 Jog

8 to 10 12.9 to 16.1 Run

10 to 13 16.1 to 21 Fast run

>13 >21 Advanced runner

-1 to -3 -1.6 to -4.8 Walk

>-4 >-6.4 Careful, becomes difficult quickly

To determine the maximum speed for your particular treadmill model, see “Appendix A: Anti-Gravity

Treadmill Specifications”.

Adjusting Body Weight

To minimize any discomfort while exercising, adjust the user’s body weight. It may not be necessary to

reduce weight by a large percentage to feel a considerable change. Start with a small percentage; a

reduction of only a few percentage points can significantly change your perceived exertion.

As the user’s conditioning gets better and they become accustomed to running, they will find that you can

incrementally increase their body weight and remain comfortable.

CAUTION: Change body weight percentage slowly at lower values (<50%). When

operating at low percentage body weights, do not allow the user to jump or perform other

unusual maneuvers. At such light weights, the user can become elevated off the treadmill

surface to the point of becoming unstable.

D000449-00 Rev. D 9-July-2021

Starting Live Video Monitoring

Operator User Action Screen

A built-in camera at the front of the treadmill belt (photo

shown on the right) enables live video monitoring of the

user’s gait.

1. Tap VIDEO on the session screen. A live video

showing the user’s gait is displayed in the middle of

the display area.

This feature is helpful because the camera view

may show an abnormal gait that the user cannot

otherwise feel.

2. Tap SESSION to return to the session screen.

Displaying Gait Analytics

Understanding gait parameters:

• The load cells have an 85lb (39kg) threshold. The load cells on the Anti-Gravity Treadmill need at

least an 85lb (39kg) load to supply gait data. This threshold is not a fixed demarcation; it may be

closer to 80lbs (36kg) or 90lbs (41kg) on different systems with different individuals. This becomes

important when using gait analysis with lower weight patients. For example, at a reduction of 20%

body weight, a person with an AlterG weight (see AlterG weight below) of 115lbs (52kg) is at the 85lb

(39kg) threshold.

• AlterG weight is less than normal weight. The bag supports a portion of a person’s body weight,

even when the dashboard indicates 100% body weight. This is important when considering the 85lb

(39kg) load cell threshold. For example, a person who normally weighs 150lbs (68kg) may weigh

approximately 145lbs (66kg) when zipped into the Anti-Gravity Treadmill.

• Walking mode. A 3-step rolling average is used to calculate an average of the gait data.

D000449-00 Rev. D 9-July-2021

• Rolling average. The gait data is analyzed using a rolling average; therefore, the gait data is on a

delay of approximately a half second.

• Recording gait data. A gait recording needs to be uninterrupted in addition to being started and

finished using the same “mode”. As a result, if a step is dropped (not recorded) at any point during the

recording, the gait clip will be stopped at the point where it was interrupted.

• Increasing treadmill incline. The gait data may become inaccurate while increasing the treadmill

incline because the treadmill begins to lift off the load cells. As a result, the load cells may not sense

any weight, which means they cannot communicate any gait data. This can occur at incline degrees

as low as 1 degree, depending on the weight and footfall of the person using the treadmill.

• Tap Stop (red button). The Anti-Gravity

Treadmill slows to a stop first, and then

deflates the pressure.

• If the user experiences discomfort while

exercising, pull on the emergency stop lanyard

and displace the magnet. This puts the

treadmill in freewheel mode and pressure. If

the treadmill is stopped in this manner, the user

should continue to step in place to avoid

becoming light-headed.

Upon stopping, the Session Complete screen

appears. The user’s average running pace and

average body weight for the entire workout session

are displayed. These averages will be low if the

user performs a slow warmup. For a better

indication of the user’s workout pace, have the user

perform a warmup and then start a new workout

session at their workout pace.

• Gently lower the enclosure and frame to the surface of the treadmill.

• Exit the treadmill. Have the user turn around and carefully step out of the back of the treadmill.

D000449-00 Rev. D 9-July-2021

Operating Optional Accessories

Heart Rate Monitor

The Anti-Gravity Treadmill display is designed to receive a user’s heart rate in conjunction with the use of

a Polar® (Chest Strap) Heart Rate Monitor. For the screen to correctly display a user’s heart rate, the

receiver within the display must obtain a stable heart rate signal from the Polar transmitter. The Polar

Heart Rate System consists of 3 main elements:

• Chest band/strap

• Sensor/transmitter

The sensor/transmitter is worn just below the chest and at the top of the abdomen, directly on bare

skin (not over clothing.) The transmitter should be centered below the pectoral muscles. When the

strap is secured, pull it away from the chest by stretching the band, and moisten the conductive

electrode strips with plain water. The transmitter operates automatically while the user is wearing it. It

does not operate while it is disconnected from the user’s body. However, moisture may activate the

transmitter and salt buildup from sweat can be a problem. Rinse the belt with water and wipe it dry

after use. The chest band is washable. After detaching the transmitter, wash the band in warm water

using mild soap, and rinse thoroughly in clean water. Never scrub the transmitter surfaces.

• Receiver

The user must be within 2½ feet of the receiver for the signal to be received. Note that the transmitter

may fluctuate erratically if the user is too close to other Polar equipment. A distance of at least 3 feet

must be maintained between other Polar units. Erratic heart rate reception may occur if the Polar

Monitor is too close to strong sources of electromagnetic radiation, such as television sets, personal

computers, electric motors, and other types of fitness equipment. Only one transmitter should be

used inside the range of any one receiver because the receiver may pick up several signals

simultaneously, causing an inaccurate readout.

Labels, Locations, Interpretation

You must read and understand the labels on the Pro 500 Anti-Gravity Treadmill. The labels provide

information on the operation of the Anti-Gravity Treadmill. Follow all instructions on the labels for a safe

and enjoyable exercise experience.

Should any label become damaged and unreadable, contact AlterG immediately to order a replacement.

The locations of the labels are indicated in the diagram below. A graphical representation and detailed

description of each label follow.

Label #1

This is the service contact label. It displays the phone number, email, and website to contact for

support and repair.

& 10

D000449-00 Rev. D 9-July-2021

Label #2

This label is located on areas of the Anti-Gravity Treadmill

frame that present a pinch hazard when the enclosure is

inflated. The metal frame of the Anti-Gravity Treadmill helps to

shape and contain the fabric enclosure. As the enclosure

inflates, the enclosure expands to touch the frame in the areas

where the labels are placed. Hands or any other part of the

body should not be placed in these areas between the

enclosure and frame.

Label #3

This label is located on the two safety latches used to secure the oval support frame into the vertical

height adjusters. For your safety, it is critical that you close and lock the latches after installing the oval

support bar and before exercising. The latches should always be closed when the fabric enclosure is

inflated. Never open these latches during exercise or during calibration when the enclosure is

pressurized.

Label #4/Label #10 (Overlay)

Label #4, Emergency Stop. The emergency stop label is located on the control pod below the

touchscreen. It indicates where the safety magnet should be placed for operation of the Anti-Gravity

Treadmill. If the safety magnet is not placed on the circular stud below the words “EMERGENCY

STOP”, the Anti-Gravity Treadmill will not operate. In use, if any sort of emergency should arise, a tug

on the lanyard attached to the magnet will displace the magnet and stop the treadmill. Always clip the

safety lanyard to the user’s clothing prior to starting the workout.

Label #10, PC On/Off Button. Note that the PC On/Off button is on the underside of the control pod.

Using this button powers the software on/off; it does not power the Anti-Gravity Treadmill.

#10

D000449-00 Rev. D 9-July-2021

Label #5

Users must be in good health to exercise on the Anti-Gravity Treadmill. Users must consult a physician

before beginning an exercise program on the treadmill. If a user experiences any pain, discomfort or

unusual symptoms while exercising on the treadmill, they must stop immediately and consult their

physician before resuming an exercise program. You and your users must be trained in the use of the

treadmill and its safety features prior to starting a workout session. Do not use the treadmill, unless

properly instructed. Always use the safety lanyard. Clip the safety lanyard to the user’s clothing prior to

exercise. Clip it in a manner that will cause the safety magnet to be pulled from its resting position on

the console should the user fall. The treadmill will stop in response to the removal of the safety magnet.

Label #6

This label is located on the lower right corner of the tubular frame surrounding the touchscreen and

console.

The oval support frame must be secured in the vertical height adjusters and the safety latches must be

closed before the user begins exercising. This label is affixed at the front of the oval support frame on

the top. Be certain to follow these instructions.

Label #7

It is very important that you read and understand this manual

for safe operation of the Anti-Gravity Treadmill. This label is

located on the lower left corner of the tubular frame

surrounding the touchscreen and console. The Anti-Gravity

Treadmill is not your ordinary treadmill. It is a sophisticated

training system with unique features that you must thoroughly

understand before using.

D000449-00 Rev. D 9-July-2021

Label #8

AlterG manufactures the system. This label is located on the base of the Anti-Gravity Treadmill and

identifies the serial and model number of the system as well as the power and voltage requirements.

Label #9

This label is located within the structure of the Anti-Gravity

Treadmill and indicates that a high voltage is present in that

location. If you see this label, do not get close to or

disassemble any of the components to which it is attached.

Because the high voltage can cause serious injury or death,

only a qualified AlterG service technician should attempt any

repairs.

Label #11

This label is located next to the product label on the front

panel near the base of the Anti-Gravity Treadmill. It indicates

that this product can expose you to chemicals which are

known to the State of California to cause cancer or birth

defects or other reproductive harm. For more information, visit

www.P65Warnings.ca.gov.

D000449-00 Rev. D 9-July-2021

Maintenance

To ensure the safe operation and longevity of your Pro 500 Anti-Gravity Treadmill, you must perform

periodic maintenance. You can perform many maintenance tasks yourself; however, it is recommended

that an AlterG technician inspect the system every 12 months.

CAUTION: Make sure the Anti-Gravity Treadmill is turned off and unplugged before

performing any of the maintenance detailed below.

Disinfection

Shorts Cleaning and Disinfection

• Before the user puts on or takes off the AlterG’s Shorts, make sure they always remove their shoes.

Keeping shoes on while putting on the shorts puts a great deal of stress on their seams and will

significantly reduce the life of the shorts.

• If any part of the shorts wears out, discontinue use.

Washing Instructions: Wash by hand or machine wash on gentle cycle. When using a washing machine

place shorts in a mesh bag. Use a mild detergent. Air dry. Do not place the shorts in the dryer.

AlterG’s Shorts should be cleaned and disinfected in accordance with standing clinical policy regarding

patient apparel and the degree of exposure risk. Consult the CDC website for the latest guidelines on

decontamination of patient equipment and apparel.

Standard cleaning can be carried out with submersion in anti-microbial compounds and mechanical

agitation. Follow guidelines for the particular anti-microbial cleaners that are in use when you determine

decontamination exposure time and method. AlterG Shorts material construction is of neoprene and

urethane; you can consult the manufacturer of your preferred cleaning agents regarding suitability and

directions for use. The shorts will tolerate exposure to a 10% bleach solution.

Follow CDC recommended procedures for decontamination when shorts become exposed to human

waste or blood or when high-risk patients or high-risk microbial contamination is involved. Disposal of the

shorts following exposure to waste, blood or highly contagious microorganisms or when patients at high

risk for infection are involved is recommended.

Direct exposure of the shorts to solid waste (feces) blood or broken skin is considered an unusual

condition and it may be impossible to adequately disinfect shorts under these circumstances. Shorts

which are exposed to higher contamination risk situations should be removed from use beyond the

immediate user and sterilized between uses if they are deemed safe for reuse in a particular individual. If

broken skin, incontinence or high-risk microbial contamination is possible the situation should be

evaluated on a case by case basis.

It is recommended that patients at high risk for urinary or fecal incontinence wear liners, diapers, and

other effective means of damming, retention and absorption. Avoid transferring waste or infectious

organic matter to the interior of the treadmill because it is very difficult to eliminate organic contamination

after it is introduced into the interior of the treadmill.

Urinary catheters and other conduit and enclosure-based waste storage devices should be used with

caution and awareness that the treadmill’s internal environment reaches a pressure higher than

atmospheric. This pressure difference can pressurize catheter systems, causing then to swell, leak or

burst.

Enclosure and Frame Cleaning and Disinfection

Wipe the surfaces of the Anti-Gravity Treadmill fabric shell and tubular framework with 10% bleach

solution or other detergents/disinfectants that are compatible with urethane coatings and epoxy-based

paint films and meet the CDC’s guidelines for disinfection. Do not soak surfaces to the point that the

bleach solution begins to run. Regular cleaning and wiping of the surfaces after each use is

D000449-00 Rev. D 9-July-2021

recommended. Following exposure to infectious agents, clean the surfaces of the treadmill in accordance

with CDC guidelines or consult AlterG, Inc.

General Cleaning and Inspection

Periodic cleaning and inspection will help lengthen the life of your Anti-Gravity Treadmill and keep it

looking good. The biggest contributor to the failure of the treadmill will be dirt and debris accumulation

inside the treadmill. To prevent this, ensure users always wear clean shoes while they exercise. Because

the treadmill is a sealed system, the presence of dirt and debris greatly reduces the longevity of the

product.

Keeping the system clean will also make it easier to see any problems that might not otherwise be found

until it is too late. Below is a general guideline on cleaning and maintenance intervals. If the Anti-Gravity

Treadmill is in a dirty environment or under heavy use, cleaning and inspection intervals should occur

more frequently. Do not use abrasive brushes or cleaners; they will mar and scratch the paint and plastic

surfaces. Also, do not soak any surface with a liquid because the sensitive electronics can be damaged

and introduce an electrical hazard.

Daily

1. Inspect and remove any loose debris from the interior of the enclosure.

2. Check for abnormal operation. Ensure that there are no unusual performance characteristics such as:

• Unusual sounds, such as hissing of air leaks, from the treadmill, air blower, or enclosure.

• Unusual sights or odors that appear out of the ordinary.

• Any operational characteristics that have changed, such as reduced treadmill speed or erratic or

low enclosure pressure. Note that low enclosure pressure can be caused by a miscalibration.

Ensure that you have properly followed the calibration steps before you determine that there is a

pressurization problem.

Weekly

1. Check the overall condition of the treadmill.

2. Inspect the height adjusters used to position the oval support frame for wear or damage.

3. Inspect the safety latches for proper function and unusual wear.

4. Inspect the enclosure for tears or leaks.

5. Wipe down exterior surfaces with a damp cloth. This will help prevent the windows from yellowing.

6. Wipe the enclosure and monitor when needed using a microfiber cloth to avoid scratches. Note: Wipe

the monitor when the treadmill is off. If you press on the touchscreen when the treadmill is on, you

may accidentally activate a function.

7. Check for loose wires and cables.

8. Vacuum the interior of the enclosure through the access hole in the top of the enclosure. You can

position the oval support frame in the highest position and crawl inside the enclosure for better

access.

9. Vacuum around the base of the treadmill.

10. Check shorts for rips or holes.

Monthly

1. Remove the enclosure from the frame and thoroughly vacuum the interior of the treadmill. See the

instructions that follow.

2. Vacuum any dust accumulated on the screens located inside the blower intake tubes on either side of

the front of the treadmill.

D000449-00 Rev. D 9-July-2021

Seasonally

In autumn and winter the drier climate in many regions of the country will cause static buildup when the

treadmill is used. Spray the running surface with a staticide spray to prevent static shock to treadmill

users and to prevent interference with the treadmill’s electronic systems.

Enclosure Windows

The windows on your Anti-Gravity Treadmill are made of Strataglass™. Special care must be taken to

ensure they remain clean and clear. IMAR™ Strataglass cleaner is recommended for cleaning the clear

windows.

Note: If your Anti-Gravity Treadmill is exposed to the sun, it is necessary to order a special window

cleaner that contains UV protection. For a list of retailers and distributors in your area, contact AlterG or

visit Amazom.com and order the IMAR™ Strataglass protective cleaner. If you have any problems with

your Strataglass, contact AlterG immediately.

Height Adjusters and Latch Mechanism

• The height adjusters function as an essential safety mechanism in the event that a user falls. Always

check the height adjuster prior to each use. Make sure they are not loose or cracked and that the

oval support frame pins fit in each slot. Check the notches for wear.

• Inspect the safety latches that secure the oval support frame in the notches. Make sure they function

smoothly, close completely, and are always pinned closed during use.

Touchscreen

With continued use, the touchscreen will be covered in fingerprints. Use a microfiber cloth to avoid

scratching the screen surface. Before cleaning the touchscreen, turn the treadmill off. Otherwise, when

you clean the touchscreen, you apply pressure that the computer might recognize as a touch.

You can use any standard glass cleaner, but DO NOT use products containing ammonia. When cleaning

the touchscreen, use a microfiber cloth dampened with soap and water to avoid scratching the screen

surface.

Always spray the cleaner on the cloth first and then clean the touchscreen. Glass cleaner sprayed directly

on the monitor could leak inside a non-sealed unit and cause damage.

The iKlear

cleaning kit is recommended for cleaning the touchscreen.

Enclosure Maintenance

• Check the enclosure for any leaks and note any abnormal hissing sounds. A small leak through the

shorts and zipper is normal. If this or other leaks affect the maximum pressure capabilities of the Anti-

Gravity Treadmill, contact AlterG for troubleshooting and support.

• Lubricate the zipper on the enclosure as needed using a zipper lubricant. Keep sharp objects away

from the enclosure at all times.

• To provide maintenance on the inside of the Anti-Gravity Treadmill, it may be necessary to remove

the enclosure from the base. It is recommended that this type of maintenance be performed at the

end of the day. When the enclosure is reattached, the foam that forms an airtight seal between the

enclosure and the base requires time to expand and reseal. The procedure for removing the

enclosure for cleaning is described below.

Enclosure Removal Procedure for Cleaning

To provide maintenance on the inside of the Pro 500 Anti-Gravity Treadmill, it may be necessary to

remove the enclosure from the treadmill base. Follow the steps in this section to remove, clean inside,

and replace the enclosure. Make sure you have the slider removal tool and a mallet or hammer. The

slider removal tool is plastic, which is designed not to tear the enclosure.

Note: If you lose the slider removal tool, call AlterG to obtain a replacement.

D000449-00 Rev. D 9-July-2021

Enclosure Removal and Cleaning

1. Power off and unplug the Anti-Gravity Treadmill.

2. Locate the metal strips under the metal tabs at the

base of the enclosure. The metal strips are retained by

black plastic sliders that slide under the metal tabs.

3. Use the slider removal tool to slide the black plastic

sliders side-ways out from under the metal tabs, as

shown in this illustration.

Take care not to cut the enclosure. To prevent the

slider removal tool from slipping off the tabs, gently tap

the end of the plastic tool with a mallet to ease out the

black plastic sliders.

4. After you slide out all the plastic tabs on the frame, tilt

the metal slat towards the inside of the treadmill. In the

locked down position, the metal slat should be at a 45-

degree angle pointing towards the outside of the

treadmill. You may have to push down on the slat as

you rotate it inwards.

5. Lift the slats and pull them out. Collect the black

plastic tabs. There are 28 tabs: 10 on each side, 4 on

the front, and 4 on the back.

D000449-00 Rev. D 9-July-2021

6. Lift the base of the enclosure up and inward away

from the retaining tabs.

Note that you may not need to remove both the front

and back to clean the entire treadmill. Removing one

end and both sides should be sufficient. Typically, it is

best to leave the front of the enclosure attached to the

frame.

As shown in the illustration, the enclosure has been

released on both sides and the back. The front of the

enclosure remains attached. You can suspend the

enclosure for better access by placing the oval support

frame in the vertical height adjusters. Be sure to close

the safety latches.

7. Thoroughly vacuum all surfaces you can reach. Get as

far under the treadmill as possible.

Clean the back of the treadmill where dirt and debris

collect.

Enclosure Reattachment

1. A cylindrical plastic rod is sewn in the bottom of the

enclosure and fits in the small groove between the

outer edge of the wood and the inside of the metal

base.

Attach the back of the enclosure in the groove first,

and then attach the sides.

D000449-00 Rev. D 9-July-2021

2. Place the bottom edge of the metal slats on the

enclosure side of the plastic rods located in the hem of

the enclosure.

The rod should be trapped between the slat and the

outer frame.

Set the plastic sliders on the slat with the tapered end

of each slider facing the metal tab. The slat will be

angled toward the enclosure.

Using your hands, push down on the metal slat

(pushing on the plastic sliders will be more

comfortable) to clear the metal tabs, then rotate the

top edge of the slat outwards, capturing the slat under

the metal tabs.

In the illustration, the plastic sliders have been

attached and the slat is ready to be pushed down and

rotated into place.

When you place a slat, ensure that it is centered

properly with regard to the metal tabs, as shown in the

illustration. This is the rear slat, and it has an equal

overhang on each end tab.

This illustration shows the slat after it has been

pushed down and rotated outwards to capture the top

of the slat under the metal tabs.

D000449-00 Rev. D 9-July-2021

3. Slide the black plastic sliders under each metal tab on

each side of the enclosure that you are reattaching.

Push the sliders far enough such that the metal tab

rests on the flat surface of the slider. You might need

to tap the sliders into place using the plastic tool and a

mallet. Be careful not to slip and cut the enclosure.

Appendix C: Troubleshooting

In most cases, repairs to your Anti-Gravity Treadmill must be completed by an AlterG qualified technician.

Contact your AlterG representative, or request repairs at [email protected].

Before requesting help from a repair technician, you can troubleshoot the problems and potentially

resolve them.

Repairs

Note the following so that we can help you as quickly as possible.

• What is the serial number of the Anti-Gravity Treadmill? The manufacturer’s label is located on the

treadmill base.

• What happened prior to the problem?

• Did the problem occur unexpectedly?

• Did the problem worsen over time?

• If you hear an unusual noise, from where does the noise originate?

• Was someone using the treadmill at the time the problem occurred?

• Note any other symptoms that might be relevant.

• Does the screen display error messages?

Touchscreen Display

If the display is not visible, try touching the screen. If nothing happens, look at the LED light on the lower

right corner of the console. If it is not green, press the “On” button. If nothing happens, verify that the

treadmill is plugged in. If the treadmill is plugged in, check the circuit breaker. If the circuit breaker is on

and the display is still blank, there may be a loose connection. Contact AlterG.

Air Pressure

If improper pressure is felt during a workout session, check shorts and unit enclosure for leaks. If

pressure issues persist, contact AlterG.

Treadmill

1. Free wheel: if the treadmill belt is free to move, check and make sure the safety magnet is on the

console in the correct location. Next, check that the treadmill is plugged in.

2. The treadmill belt will not move until you start the user interface. If the treadmill belt is moving in

another instance, contact AlterG immediately. If the treadmill belt will not move during operation, test

other functions, such as incline. If this works, check the screen for any error messages. Record any

System Error messages and contact AlterG.

Leaks

If the fabric enclosure is torn, or if the shorts are torn, discontinue use and contact AlterG.

System Errors

The Anti-Gravity Treadmill software has built in error checking to ensure that all systems are operating

within specifications. If an error is detected, “Unexpected Error” is displayed, followed by a description of

the detected error. If you see this message, write down the error message and a description of the

circumstances under which it occurred.

The error may be the result of an unexpected anomaly that may occur in complex computer-controlled

devices. If this is the case, cycle the power from the display console. This may clear the error and correct

the problem. If the error persists, contact AlterG. Note the circumstances under which the error occurs

and the diagnostic code.

Adjust Treadmill Creep

You may want to use a step stool for access to the touchscreen while you adjust the treadmill creep.

Stand next to the treadmill and install the oval support frame in the vertical height adjusters and close the

safety latches.

Operator or User Action Screen

1. On the Welcome screen, double-tap the top left

corner. A number keypad appears.

2. Enter the facility settings code, 5900, and tap OK.

The facility screen appears.

3. Tap TM CALIBRATION. The Treadmill Calibration

screen appears.

Operator or User Action Screen

4. Tap the Adjust Creep up arrow and down arrow to

adjust the belt such that it no longer creeps when

the treadmill is in standby.

• If the belt is creeping forward, tap the up arrow

to reduce the creep.

• If creeping backwards, tap the down arrow to

reduce the creep.

• There are several settings that will stop the

creep entirely. You want to find the “middle”

setting between the 2 points at which the

treadmill begins to move.

Adjustment process example (see the illustration

on the right):

The belt is creeping backwards in standby.

a) Tap the down arrow.

b) Continue tapping the down arrow until the belt

just stops moving. This is the starting point for

adjustment.

c) Continue tapping the down arrow successively,

counting the number of taps, until the treadmill

just begins to move forward.

In the example, you tapped the down arrow 5

times and on the fifth tap the belt began to

move forward. The range over which the

treadmill does not move is defined by 5 taps.

You want to leave the creep adjustment in the

middle of this range.

d) To reach the middle position, tap the up arrow

3 times.

e) Pull the safety magnet to save creep settings.

Follow the same procedure if the treadmill is

creeping forward. Tap the up arrow to arrest the

movement and establish the range over which the

treadmill stops moving. Tap the down arrow to

reach the middle of the range.

5. When finished, tap Return to exit the Treadmill

Calibration screen.
