WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
wheelchairs to meet many needs of the end user. However, final selection of the
type of wheelchair to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection. Invacare highly
recommends working with a certified rehab technology supplier and/or a member
of NRRTS or RESNA.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRRO OR
TRBKTS)
TRRO includes four factory-installed transport brackets and a wheelchair anchored
pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1
Section 19 Frontal Impact Test requirements for wheelchairs with a 168 lb crash
dummy, which corresponds to a person with a weight of 114 to 209 lbs.
TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has
not been crash-tested in accordance with WC 19. Use these transport brackets only
to secure an unoccupied wheelchair during transport.
As of this date, the Department of Transportation has not approved any tie-down
systems for transportation of a user while in a wheelchair, in a moving vehicle of any
type. It is Invacare’s position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the restraints
made available by the auto industry. Invacare cannot and does not recommend any
wheelchair transportation systems.
Refer to Transport Ready Package (TRRO) on page 64 for more information about
transporting the wheelchair.

TDX™ SP
SPECIAL NOTES
TRRO AND TRBKTS WARNINGS
Only use the transport brackets included with TRRO and TRBKTS for the purposes
described in this manual.
Battery support brackets MUST be installed at all times. Otherwise, the wheelchair
will not be WC/19 compliant. Refer to Removing/Installing the Batteries From/Into
the Wheelchair on page 57.
WARNING
Invacare products are specifically designed and manufactured for use in conjunction
with Invacare accessories. Accessories designed by other manufacturers have not
been tested by Invacare and are not recommended for use with Invacare products.
The seat positioning strap is a positioning belt ONLY. It is not designed for use as a
safety device withstanding high stress loads such as auto or aircraft safety belts. If
signs of wear appear, belt MUST be replaced IMMEDIATELY.
The drive behavior initially experienced by the user may be different from other
wheelchairs previously used. This power wheelchair has Invacare’s SureStep®
technology, a feature that provides the wheelchair with optimum traction and
stability when driving forward over transitions and thresholds of up to 3-inches. The
following warnings apply specifically to the SureStep feature:
• DO NOT use on inclines greater than 9°.
• DO NOT use on inclines with wet, slippery, icy or oily surfaces. This may include
certain painted or otherwise treated wood surfaces.
• DO NOT traverse down ramps at high speed. Doing so will reduce traction and
increase stopping distance.
• The end user’s weight can materially affect traction on sloped surfaces. Great
care should be taken when traversing such slopes.
To determine and establish your particular safety limits, practice use of this product
on various sloping surfaces in the presence of a qualified healthcare provider before
attempting active use of this wheelchair. Other general warnings listed within this
document also apply.
Wheelchairs should be examined during maintenance for signs of corrosion (water
exposure, incontinence, etc.). Electrical components damaged by corrosion should
be replaced IMMEDIATELY.
Wheelchairs that are used by incontinent users and/or are frequently exposed to
water may require replacement of electrical components more frequently.

SECTION 1—GENERAL GUIDELINES
SECTION 1—GENERAL GUIDELINES
WARNING
SECTION 1 - GENERAL GUIDELINES contains important information for the safe
operation and use of this product. DO NOT use this product or any available
optional equipment without first completely reading and understanding these
instructions and any additional instructional material such as Owner’s Manuals,
Service Manuals or Instruction Sheets supplied with this product or optional
equipment. If you are unable to understand the Warnings, Cautions or Instructions,
contact a healthcare professional, dealer or technical personnel before attempting
to use this equipment - otherwise, injury or damage may occur.
Repair or Service Information
Set‐up of the Electronics Control Unit is to be performed only by a qualified technician. The final adjustments of the controller may affect other activities of the wheelchair. Damage to the equipment could occur if improperly set‐up or adjusted. Except for programming, DO NOT service or adjust the wheelchair while occupied, unless otherwise noted.
A pinch point exists between head tube cap and walking beam. A pinch point exists between walking beam/head tube cap and telescoping tube when TDX is at the lowest seat to floor height.
Before adjusting, repairing or servicing the wheelchair, ALWAYS turn the wheelchair power Off, otherwise, injury or damage may occur.
Invacare products are specifically designed and manufactured for use in conjunction with Invacare accessories. Accessories designed by other manufacturers have not been tested by Invacare and are not recommended for use with Invacare products.
Transport ready packages are not retrofittable to existing models and are not field serviceable. Battery retention brackets MUST be installed at all times. Otherwise, the wheelchair will not be WC/19 compliant. Refer to Removing/Installing the Batteries From/Into the Wheelchair on page 57.
Wheelchairs should be examined during maintenance for signs of corrosion (water exposure, incontinence, etc.). Electrical components damaged by corrosion should be replaced IMMEDIATELY.

TDX™ SP
SECTION 1—GENERAL GUIDELINES
Operation Information
Performance adjustments should only be made by professionals of the healthcare field or persons fully conversant with this process and the driverʹs capabilities. Incorrect settings could cause injury to the driver, bystanders, damage to the wheelchair and to surrounding property.
After the wheelchair has been set‐up/adjusted, check to make sure that the wheelchair performs to the specifications entered during the set‐up procedure. If the wheelchair does NOT perform to specifications, turn the wheelchair Off immediately and reenter set‐up specifications. Repeat this procedure until the wheelchair performs to specifications.
DO NOT leave the power button On when entering or exiting your wheelchair.
DO NOT attempt to drive over curbs or obstacles greater than 3 inches. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the wheelchair. ALWAYS stop before climbing an obstacle. Approach slowly until casters contact the obstacle. Apply power and the action of the SureStep feature will lift the casters over the obstacle. Weight is transferred to the drive wheels providing traction and motor strength to power the wheelchair over the obstacle.
DO NOT operate on roads, streets or highways.
DO NOT climb, go up or down ramps or traverse slopes greater than 9°.
DO NOT attempt to move up or down an incline with water, ice or oil film.
DO NOT stand on the frame of the wheelchair.
DO determine and establish your particular safety limits by practicing bending, reaching and transferring activities in the presence of a qualified healthcare professional before attempting active use of the wheelchair.
DO NOT attempt to reach objects if you have to move forward in your seat. DO NOT attempt to reach objects if you have to pick them up from the floor by reaching between your knees.
DO NOT lean over the top of the back upholstery to reach objects behind you, as this may cause the wheelchair to tip over.
ALWAYS shift your weight in the direction you are turning. DO NOT shift your weight in the opposite direction of the turn. Shifting your weight in the opposite direction of the turn may cause the inside drive wheel to lose traction and the wheelchair to tip over.
DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair and/or seating system (if any) may tip over.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.
DO NOT use the footplates as a platform. When getting in or out of the wheelchair, make sure that the footplates are in the upward position or swing footrests towards the outside of the wheelchair.
NEVER leave an unoccupied wheelchair unattended on an incline.
TDX™ SP

Part No 1143190
SECTION 1—GENERAL GUIDELINES
DO NOT attempt to stop a moving wheelchair with the wheel locks. Wheel locks are not brakes.
DO NOT attempt to lift the wheelchair by any removable (detachable) parts. Lifting by means of any removable (detachable) parts of the wheelchair may result in injury to the user or damage to the wheelchair.
DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.
ALWAYS wear your seat positioning strap. The seat positioning strap is a positioning belt ONLY. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST be replaced immediately.
ALWAYS turn the wheelchair power off and engage the motor locks/clutches to prevent the wheels from moving before attempting to transfer in or out of the wheelchair. Also make sure every precaution is taken to reduce the gap distance. Align both casters parallel with the object you are transferring onto.
DO NOT use with a broken or missing joystick knob.
DO NOT use if joystick does not spring back to the neutral position or becomes sticky or sluggish.
DO NOT use if joystick boot is torn or damaged.
ALWAYS check foam grips for looseness before using the wheelchair. If loose, contact a qualified technician for instructions.
ALWAYS engage both wheel locks and reduce the gap distance before transferring to and from the wheelchair. Turn all casters parallel to the object you are transferring onto.
Avoid storing or using the wheelchair near open flame or combustible products. Serious injury or damage to property may result.
DO NOT engage or disengage the motor locks until the power is in the off position.
Wheelchairs with TRRO or TRBKTS Only
Only use the transport brackets included with TRRO and TRBKTS for the purposes described in this manual.
Tire Pressure
DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). DO NOT overinflate the tires. Failure to follow these recommendations may cause the tire to explode and cause bodily harm. The recommended tire pressure is listed on the side wall of the tire.

SECTION 1—GENERAL GUIDELINES
Electrical
Grounding Instructions
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or for Invacare products. Some devices are equipped with three‐prong (grounding) plugs for protection against possible shock hazards. Where a two‐prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to contact a qualified electrician and have the two‐prong receptacle replaced with a properly grounded three‐prong wall receptacle in accordance with the National Electrical Code. If you must use an extension cord, use only a three‐wire extension cord having the same or higher electrical rating as the device being connected. In addition, Invacare has placed RED/ORANGE warning tags on some equipment. DO NOT remove these tags.
Batteries
The warranty and performance specifications contained in this manual are based on the use of deep cycle gel cell batteries. Invacare strongly recommends their use as the power source for this unit.
Carefully read battery/battery charger information prior to installing, servicing or operating your wheelchair.
Charging Batteries
DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the device being connected. Use of improper extension cord could result in risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock hazard to the user.
NEVER attempt to recharge the batteries by attaching cables directly to the battery terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.
DO NOT operate wheelchair with extension cord attached to the AC cable.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed to any type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.
DO NOT sit in the wheelchair while charging the batteries.
READ and CAREFULLY follow the manufacturer’s instructions for each charger (supplied or purchased). If charging instructions are not supplied, consult a qualified technician for proper procedures.
Ensure the pins of the extension cord plug are the same number, size, and shape as those on the charger.
TDX™ SP
18
Part No 1143190
SECTION 1—GENERAL GUIDELINES
DO NOT under any circumstances cut or remove the round grounding plug from the charger AC cable plug or the extension cord plug.
Rain Test
Invacare has tested its power wheelchairs in accordance with ISO 7176 “Rain Test”. This provides the end user or his/her attendant sufficient time to remove his/her power wheelchair from a rain storm and retain wheelchair operation.
DO NOT leave power wheelchair in a rain storm of any kind.
DO NOT use power wheelchair in a shower. DO NOT leave power wheelchair in a damp area for any length of time.

SECTION 2—EMI INFORMATION
SECTION 2—EMI INFORMATION
WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION
REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC
INTERFERENCE ON YOUR POWERED WHEELCHAIR.
Electromagnetic Interference (EMI) From Radio Wave Sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to
as powered wheelchairs) may be susceptible to electromagnetic interference (EMI),
which is interfering electromagnetic energy (EM) emitted from sources such as
radio stations, TV stations, amateur radio (HAM) transmitters, two way radios, and
cellular phones. The interference (from radio wave sources) can cause the powered
wheelchair to release its brakes, move by itself, or move in unintended directions. It
can also permanently damage the powered wheelchair's control system. The
intensity of the interfering EM energy can be measured in volts per metre (V/m).
Each powered wheelchair can resist EMI up to a certain intensity. This is called its
"immunity level." The higher the immunity level, the greater the protection. At this
time, current technology is capable of achieving at least a 20 V/m immunity level,
which would provide useful protection from the more common sources of radiated
EMI.
There are a number of sources of relatively intense electromagnetic fields in the
everyday environment. Some of these sources are obvious and easy to avoid.
Others are not apparent and exposure is unavoidable. However, we believe that by
following the warnings listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
1) Hand-held Portable transceivers (transmitters-receivers with the antenna
mounted directly on the transmitting unit. Examples include: citizens band (CB)
radios, "walkie talkie", security, fire and police transceivers, cellular telephones,
and other personal communication devices).
NOTE: Some cellular telephones and similar devices transmit signals while they are ON,
even when not being used.
2) Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulances and taxis. These usually have the antenna mounted on the outside of
the vehicle; and
3) Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM)
radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, cassette players, and small appliances, such as electric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to
your powered wheelchair.

Part No 1143190
SECTION 2—EMI INFORMATION
WARNING
Powered Wheelchair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the
transmitting antenna (source), the EM fields from hand-held radio wave sources
(transceivers) are of special concern. It is possible to unintentionally bring high
levels of EM energy very close to the powered wheelchair's control system while
using these devices. This can affect powered wheelchair movement and braking.
Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered wheelchair.
Electromagnetic interference (EMI) from sources such as radio and TV stations,
amateur radio (HAM) transmitters, two-way radios, and cellular phones can affect
powered wheelchairs and motorized scooters. Also, the electronics used in our
powered wheelchair can generate a low level of electromagnetic interference,
which however will remain within the tolerances permitted by law.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD REDUCE THE
CHANCE OF UNINTENDED BRAKE RELEASE OR POWERED WHEELCHAIR
MOVEMENT WHICH COULD RESULT IN SERIOUS INJURY.
1) Do not operate hand-held transceivers (transmitters receivers), such as citizens
band (CB) radios, or turn ON personal communication devices, such as cellular
phones, while the powered wheelchair is turned ON;
2) Be aware of nearby transmitters, such as radio or TV stations, and try to avoid
coming close to them;
3) If unintended movement or brake release occurs, turn the powered wheelchair
OFF as soon as it is safe;
4) Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more susceptible to EMI (NOTE: There is no easy way
to evaluate their effect on the overall immunity of the powered wheelchair); and
5) Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a source of EMI nearby.
Important Information
1) 20 volts per metre (V/m) is a generally achievable and useful immunity level
against EMI (as of May 1994) (the higher the level, the greater the protection);
2) This device has been tested to a radiated immunity level of 20 volts per meter.
3) The immunity level of the product is unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the EMI immunity levels.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 3—SAFETY/HANDLING OF
WHEELCHAIRS
“Safety and Handling” of the wheelchair requires the close attention of the wheelchair user as well as the assistant. This manual points out the most common procedures and techniques involved in the safe operation and maintenance of the wheelchair. It is important to practice and master these safe techniques until you are comfortable in maneuvering around the frequently encountered architectural barriers.
Use this information only as a “basic” guide. The techniques that are discussed on the following pages have been used successfully by many.
Individual wheelchair users often develop skills to deal with daily living activities that may differ from those described in this manual. Invacare recognizes and encourages each individual to try what works best for him/her in overcoming architectural obstacles that they may encounter, however all warnings and cautions given in this manual MUST be followed. Techniques in this manual are a starting point for the new wheelchair user and assistant with “safety” as the most important consideration for all.
Stability and Balance
WARNING
ALWAYS wear your seat positioning strap. The seat positioning strap is a
positioning belt ONLY. It is not designed for use as a safety device withstanding high
stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST
be replaced immediately.
DO NOT climb, go UP or DOWN ramps or traverse slopes greater than 9°.
Invacare strongly recommends proceeding down ramps or slopes slowly to avoid
hard braking or sudden stops.
DO NOT leave elevating legrests in the fully extended position when proceeding
down ramps or slopes.
Be aware that carrying heavy objects on your lap while occupying the wheelchair
may adversely affect the stability of the wheelchair, resulting in serious bodily injury
to the user, damage to the wheelchair and surrounding property.
This wheelchair has been designed to accommodate one individual. If more than
one individual occupies the wheelchair this may adversely affect the stability of the
wheelchair, resulting in serious bodily injury to the user and passenger and damage
to the wheelchair and surrounding property.

Part No 1143190
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
WARNING
DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees.
Many activities require the wheelchair user to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to the normal balance,
center of gravity, and weight distribution of the wheelchair. To determine and
establish your particular safety limits, practice bending, reaching and transferring
activities in several combinations in the presence of a qualified healthcare
professional before attempting active use of the wheelchair.
Proper positioning is essential for your safety. When reaching, leaning, bending or
bending forward, it is important to use the casters as a tool to maintain stability and
balance.
To assure stability and proper operation of your wheelchair, you must at all times maintain proper balance. Your wheelchair has been designed to remain upright and stable during normal daily activities as long as you DO NOT move beyond the center of gravity. DO NOT lean forward out of the wheelchair any further than the length of the armrests. Make sure the casters are pointing in the forward position whenever you lean forward. This can be achieved by advancing the wheelchair and then reversing it in a straight line.
Coping with Everyday Obstacles
NOTE: For this procedure, refer to FIGURE 3.1
Coping with the irritation of everyday obstacles can be somewhat alleviated by learning how to manage your wheelchair. Keep in mind your center of gravity to maintain stability and balance.
While the walking beam allows you to traverse up to a 3‐inch bump or threshold, stopping after the wheels cross the bump poses a problem. The wheelchair cannot reverse over the bump at this point. Continue forward and then turn around.
While the TDX is designed for use primarily in and around the home, the provider should determine whether this wheelchair is suitable for the actual environment in which the wheelchair will be used.
NOTE: DO NOT go down a ramp at full speed. Bump/Threshold
Some seat/back positions will cause the wheelchair to feel unstable.
CAUTION
Be aware of the condition of the ramp.
Traction will be diminished/nonexistent
on a slippery surface. Proceed with
caution.

Drive Select Toggle Switch
The drive select toggle switch is located on the left side, below the LCD. The drive select position is momentary, meaning that it will return to the neutral position after a selection is made.
This switch allows the operator to select the type of operation or performance which best suits a particular control need or situation. The DRIVE 1 program uses performance values which are independent of those used for the DRIVE 2 or 3 or 4 program. As an example, an operator may have a control need for spasticity in the morning and a very different need in the afternoon. DRIVE 1 can be programmed for higher speeds and quicker response while DRIVE 2 can be programmed for slower speeds and less responsiveness or vise versa. The other two drive programs could be indoor and outdoor versions of DRIVE 1 and DRIVE 2.

WARNING
The use of rubber gloves is recommended when working with batteries.
Invacare strongly recommends that battery installation and battery replacement
always be done by a qualified technician.
After ANY adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may result.
22NF batteries weigh 37 pounds each. Use proper lifting techniques (lift with your
legs) to avoid injury.
ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient
method and assures that the battery acid will not spill. It also helps to prolong the
life of the battery.
DO NOT tip the batteries. Keep the batteries in an upright position.
NEVER allow any of your tools and/or battery cable(s) to contact BOTH battery
post(s) at the same time. An electrical short may occur and serious personal injury
or damage may occur.
When tightening the clamps, always use a box wrench. Pliers will “round off” the
nuts. NEVER wiggle the battery terminal(s)/post(s) when tightening. The battery
may become damaged.
The POSITIVE (+) RED battery cable MUST connect to the POSITIVE (+) battery
terminal(s)/post(s), otherwise serious damage will occur to the electrical system.
Install protective caps on POSITIVE (+) and NEGATIVE (-) battery terminals.
DO NOT remove fuse or mounting hardware from POSITIVE (+) RED battery
cable mounting screw.
Unless otherwise indicated, make sure power to the wheelchair is OFF before
performing these procedures.
After ANY adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may occur.
NOTE: If there is battery acid in the bottom of the battery tray or on the sides of the battery(ies), apply baking soda to these areas to neutralize the battery acid. Before reinstalling the existing or new battery(ies), clean the baking soda from the battery tray or battery(ies) being sure to avoid contact with skin and eyes. Determine source of contamination. NEVER install/reinstall a battery with a cracked or otherwise damaged case.

Charging Batteries
WARNING
NEVER attempt to recharge the batteries by attaching cables directly to the
battery terminals or clamps. ALWAYS use the recharging plug located on the back
of the joystick.
DO NOT attempt to recharge the batteries and operate the power wheelchair at
the same time.
During use and charging, unsealed batteries will vent hydrogen gas which is
explosive in the right concentration with air.
CAUTION
Always charge new batteries before initial use or battery life will be reduced.
NOTE: For this procedure, refer to FIGURE 10.7 on page 63.
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.
NOTE: As a general rule, batteries should be recharged daily to assure the longest possible life and minimize the required charging time. Plan to recharge the batteries when it is anticipated the wheelchair will not be used for a long period of time.
The range per battery charge using recommended batteries should be approximately 5 to 9 hours of typical operation. Extensive use on inclines may substantially reduce per charge mileage.
Description and Use of Battery Chargers
The charger automatically reduces the charge from an initially high rate to a zero reading at a fully charged condition. If left unattended, the charger should automatically shut‐off when full charge is obtained.
There are some basic concepts which will help you understand this automatic process. They are:
The amount of electrical current drawn within a given time to charge a battery is called the “charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is high, as indicated by the GREEN light on the charger. Initially, the GREEN light will stay illuminated for a short period of time followed by a longer period of off time. As a charge builds up, the charge rate is reduced, and the GREEN light will stay illuminated for a longer period of time followed by a shorter off time. WARNING
NEVER leave the charger unattended when the breaker has tripped. A fault condition exists. Unplug and discontinue using immediately. Contact an Invacare dealer.
NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the individual instructions for each charger (supplied or purchased).

1. Attach the battery charger connector to the charger port on the joystick.
2. Plug the charger’s AC power cord, or extension, into the grounded 120 VAC wall outlet.
3. Wait until charging is complete.
NOTE: Allow eight hours for normal charging. Larger batteries (greater than 55 ampere‐hours) or severely discharged batteries may require up to sixteen hours to be properly charged and equalized.
NOTE: It is advantageous to recharge frequently rather than only when necessary. In fact, a battery’s life is extended if the charge level is maintained well above a low condition.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they may need to be replaced. Contact an Invacare dealer for service.

within the preferred zone of 45 to 75
degrees to the horizontal OR within the
optional zone of 30 to 45 degrees to the

horizontal.
Optional Zone
Steeper side-view pelvic belt angles are
especially important if the pelvic belt is
intended to be used for postural support
in addition to occupant restraint in a
30°
45°
frontal crash. Steeper angles will reduce
70°
the tendency for a vertical gap to
develop between the user and the belt
due to compliance of seat cushions and
belt movement, thereby reducing the
tendency for the user to slip under the
belt and for the belt to ride up on the
soft abdomen during normal use.
Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic
belt onto the abdomen during frontal impact loading.
NOTE: For this procedure, refer to FIGURE 11.4.
1. The pelvic belt should be worn low across the front of the pelvis.
2. Position the upper‐torso belt(s) over the shoulders.
3. The belt(s) should not be held away from the body by wheelchair components or parts, including but not limited to wheelchair armrests or wheels. Refer to FIGURE 11.4 for proper and improper positioning of the belts.
4. Ensure the belt(s) are not twisted.
5. Adjust belts as firmly as possible, being mindful of user comfort.
