NOTICE
THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
Check all parts for shipping damage and test before using. In case of damage, DO NOT use. Contact Invacare/Carrier for
further instruction.
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.


WARNING
DO NOT operate on roads, streets or highways.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRRO OR TRBKTS)
Only use the transport brackets included with TRRO or TRBKTS for the purposes described in this manual.
TRRO (Transport Ready Option) - TRRO includes four factory-installed transport brackets and a wheelchair anchored
pelvic strap. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1 Section 19 Frontal Impact Test
requirements for wheelchairs with a 130 lb crash test dummy, which corresponds to a person with a weight of 125 to 165
lbs for junior seat sizes or a 168 lb crash dummy, which corresponds to a person with a weight of 165 to 300 lbs for adult
seat sizes.
TRBKTS (Wheelchair Transport Brackets) - 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 the transport ready section of the wheelchair base user manual for more information about transporting the
wheelchair.
STAIRWAYS AND ESCALATORS
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.

Powered Seating

WARNING
This seating system has been custom designed and will be assembled to the wheelchair base before delivery to the user.
The information contained in this manual is for maintaining and adjusting the seating system. There are very few
adjustments that can safely be made by the user. If there is a procedure or adjustment that needs to be performed on the
seating system that is not in this manual, DO NOT perform that procedure. Have the seating system serviced by a qualified
technician.
Use caution when driving in a tilted position.
DO NOT operate the seating system while on an incline.
DO NOT operate the seating system while the wheelchair is moving.
NEVER operate the wheelchair while in any tilted position over 20° relative to the vertical position. If the drive lock-out
does not stop the wheelchair from operating in a tilted position over 20° relative to vertical, DO NOT operate the
wheelchair. DO NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a qualified technician.
Use only the controls listed in Using the Powered Seating Switch on page 32 to activate the tilt functions. DO NOT USE
any other actuator controls. Such devices may result in excess heating and cause damage to the actuator and associated
wiring and could cause a fire, death, physical injury or property damage. If such devices are used, Invacare shall not be liable
and the limited warranty is void.
Specific actuator controls are noted for each function or combination throughout this manual.
DO NOT operate tilt seat around children.
ALWAYS keep hands and feet out from underneath tilt seat - otherwise serious injury may result.
DO NOT tip the seating system/wheelchair without assistance.
DO NOT store items under seat.
Cables must be routed and secured properly to ensure that cables DO NOT become entangled and damaged during
normal operation of seating system.

Repair or Service Information

WARNING
Except for programming, DO NOT service or adjust the wheelchair while occupied, unless otherwise noted.
Before adjusting, repairing or servicing the wheelchair, ALWAYS turn the wheelchair power Off, otherwise, injury or
damage may occur.
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.
DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing.
Transport ready packages are not retrofittable to existing models and are not field serviceable.
TDX® OR TDX SP, SR, SI, SC and SPREE WHEELCHAIR BASES ONLY
A pinch point exists between walking beam/head tube cap and telescoping tube when at the lowest seat to floor height.
POWERED SEATING SYSTEMS ONLY
Pinch point may occur when returning the tilted seat to the full upright position. Make sure the hands and body of the
occupant, attendants and bystanders are clear of all pinch points before returning the tilted seat to the full upright position.

Safety/Handling

WARNING
Refer to wheelchair base user manual for additional safety and operation information.
The seat positioning strap is a positioning strap ONLY. It is not designed for use as a safety device withstanding high stress
loads such as auto or aircraft safety straps. If signs of wear appear, strap MUST be replaced IMMEDIATELY.
DO NOT leave the power button On when entering or exiting your wheelchair.
DO NOT go UP or DOWN ramps or traverse slopes greater than 9°.
NEVER leave an unoccupied wheelchair unattended on an incline.
DO NOT attempt to move up or down an incline with water, ice or oil film.
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.
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.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.
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.

3.3
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 meter (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).

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.

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 1143192
3 SAFETY
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.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD REDUCE THE CHANCE OF UNINTENDED BRAKE RELEASE OR POWERED
WHEELCHAIR MOVEMENT WHICH COULD RESULT IN SERIOUS INJURY.

WARNING
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 meter (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 scooter as manufactured by Invacare may adversely affect the EMI
immunity levels.

A Note About Drive Lock-Out

WARNING
NEVER operate the wheelchair while the back is in any tilted/back angle position over 20° relative to the vertical position. If
the drive lock-out does not stop the wheelchair from operating in a tilt/back angle position over 20° relative to the vertical
position, DO NOT operate the wheelchair. DO NOT attempt to adjust the drive lock-out. Have the wheelchair serviced
by a qualified technician.
The wheelchair user MUST have a clear line of sight to drive safely. On initial chair delivery and after adjusting the back
angle, drive lock-out switch or tilt system, tilt the seat back to the farthest driving position immediately before drive lockout engages and ensure there is a clear line of sight present in which to drive the wheelchair. If a clear line of sight is not
present, have the back angle repositioned or readjust the lockout angle such that safe driving with a clear line of sight is
achieved. Otherwise injury or damage may occur.
One of the following will occur when the drive lock-out feature has been activated:
•
CMPJ+ Joysticks Only -  TILT WARNING or  SPM Controller Inhibited displays on the joystick or display unit.
•
SPJ+ Joysticks Only - Left to right chase alternating with a steady display.
Drive lock-out is a feature designed to prevent the wheelchair from being driven after the seating system has been tilted beyond 20°* relative to the
vertical position. The back can be positioned at a 10° relative offset to the seat base, thereby resulting in a back angle potential of 30° before which
the drive lock-out is activated. This may affect the wheelchair user’s line of sight while driving. Make sure the wheelchair user can see properly to
ensure safe driving.

*20° back angle can be any combination of tilt, back angle and/or surface angle.
Refer to Typical Product Parameters on page 26 for tilt angle ranges.
