GENERAL GUIDELINES
REPAIR OR SERVICE INFORMATION
Setup of the Electronic Control Unit is to be performed ONLY by indi-
viduals certified by Invacare. The final tuning adjustments of the control-
ler may affect other activities of the wheelchair. Damage to the equip-
ment could occur under these circumstances. If non-certified individuals
perform any work on these units, the Limited Warranty is void.
OPERATING INFORMATION
GENERAL WARNINGS
Professionals of the healthcare field or other persons should only make
performance adjustments fully conversant with this process and the
wheelchair operators capabilities. Incorrect settings could cause injury to
the driver, bystanders, damage to the chair 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 setup
procedure. If the wheelchair does NOT perform to specifications, turn
the wheelchair OFF immediately and re-enter setup specifications. Re-
peat 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
for TDX 5 and TDX 4 or greater than 2-inches for TDX 3. Doing so may
cause your wheelchair to turn over and cause bodily harm or damage to
the chair. Always stop before climbing an obstacle. Approach slowly until
casters contact the obstacle. Apply power and the action of the Sure-
Stepfeature will lift the casters over the obstacle. Weight is trans-
ferred to the drive wheels providing traction and motor strength to
power the wheelchair over the obstacle.
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 encoun-
tered, it is the personal responsibility and obligation of the customer to
contact a qualified electrician and have the two-prong receptacle re-
placed with a properly grounded three-prong wall receptacle in accor-
dance 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.

GENERAL GUIDELINESSECTION 1
WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFOR-
MATION REGARDING THE POSSI LE EFFECTS OF ELECTRO-
MAGNETIC 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 electro-
magnetic 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 inter-
ference (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 sys-
tem. 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 pro-
vide 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, 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 (C ) 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 eing used.
2) Medium-range mobile transceivers, such as those used in police cars,
fire trucks, ambulances and taxis. These usually have the antennas
mounted on the outside of the vehicle.
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 pro lems to your powered wheelchair.
GENERAL GUIDELINES

Part No. 1114822 11 Tilt/Recline Seating Systems®
GENERAL GUIDELINES SECTION 1
WARNING (CONTINUED)
Powered Wheelchair Electromagnetic Interference (EMI):
ecause 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 unin-
tentionally 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 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.
WARNING (CONTINUED)
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 (C ) radios or turn ON personal communication
devices, such as cellular phones, while the powered wheelchair is
turned ON
2) e 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) e 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) The immunity level of this product is not known.
Modification of any kind to the electronics of this wheelchair as manufa-
tured by Invacare may adversely affect the RFI immunity levels.

SAFETY/HANDLING OF SEATING SYSTEMS/
WHEELCHAIRS
Safety and Handling of the wheelchair requires the close attention of the seating
system/wheelchair user as well as the assistant. This manual, as well as the owners
manual provided with the wheelchair, points out the most common procedures and
techniques involved in the safe operation and maintenance of the seating system/wheel-
chair. It is important to practice and master these safe techniques until you are comfort-
able 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 seating system/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 architec-
tural 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 new seating system/wheelchair users and assistants with safety as the most impor-
tant consideration for all.
STABILITY AND BALANCE
WARNING
Always wear your seat positioning strap.
To assure stability and proper operation of your seating system/wheelchair, you must at
all times maintain proper balance. Your seating system/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 seating system/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
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning
how to manage your wheelchair. Keep in mind your center of gravity to maintain stabil-
ity and balance.
A NOTE TO WHEELCHAIR ASSISTANTS
When assistance to the seating system/wheelchair user is required, remember to use
good body mechanics. Keep your back straight and bend your knees.
Also, be aware of any detachable parts. These must NEVER be used to move the wheel-
chair or lifting supports, as they may be inadvertently released, resulting in possible
injury to the user and/or assistant(s).
When learning a new assistance technique, have an experienced assistant help you
before attempting it alone.

PERCENTAGE OF WEIGHT DISTRIBUTION
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 owner to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to 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 health 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 front casters as a tool to maintain stability
and balance.
GENERAL GUIDELINES SECTION 1
SAFETY AND HANDLING
REACHING, BENDING -BACKWARDS
WARNING
DO NOT lean over the top of the
back upholstery. This will change
your center of gravity and may
cause you to tip over.
Position wheelchair as close as possible to
the desired object. Point front casters
forward to create the longest possible
wheelbase. Reach back only as far as your
arm will extend without changing your
sitting position.
REACHING, LEANING, BENDING AND BENDING -
FORWARD
WARNING
DO NOT attempt to reach objects if
you have to pick them up from the
floor by reaching down between your
knees.
Position the front casters so that they are
extended as far forward as possible and
engage wheel locks.

GENERAL GUIDELINESSECTION 1
SAFETY AND HANDLING
WARNING
The weight of the wheelchair without the user and without batteries is
between 255 and 316 lbs. Use proper lifting techniques (lift with your
legs) to avoid injury.
1. Remove the occupant from the wheelchair.
2. Remove battery/batteries from wheelchair. Refer to the TDX
Owners Manual, part number 111 809.
3. Bend your knees and keep your back straight.
. Using non-removable (non-detachable) parts of the wheelchair,
lift the wheelchair off of the ground and transfer the wheelchair
up or down the stairs.
5. The wheelchair should not be lowered until the last stair has
been negotiated and the wheelchair has been carried away from the stairway.
ESCALATORS? SORRY!
DO NOT use an escalator to move a wheelchair between floors. Serious
bodily injury may occur.
STAIRWAYS - POWER CHAIRS
WARNING
DO NOT attempt to move an occupied power wheelchair between floors
using a stairway. Use an elevator to move an occupied power wheelchair
between floors. If moving a power wheelchair between floors by means of
a stairway, the occupant MUST be removed and transported indepen-
dently of the power wheelchair.
Extreme caution is advised when it is necessary to move an UNOCCU-
PIED power wheelchair up or down the stairs. Invacare recommends
using two (2) assistants and making thorough preparations. Make sure to
use ONLY secure, non-detachable parts for hand-hold supports.
DO NOT attempt to lift the wheelchair by any removable (detachable)
parts. Lifting by means of any removable (detachable) parts of a wheel-
chair may result in injury to the user or damage to the wheelchair.
Follow this procedure for moving the wheelchair between floors when an
elevator is NOT available:

GAP
DISTANCE
TRANSFERRING TO AND FROM OTHER SEATS
WARNING
ALWAYS turn the wheelchair power OFF and engage the motor locks/
clutches to prevent the wheels from moving EFORE 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.
CAUTION
When transferring, position yourself as far back as possible in the seat. This
will prevent broken screws, damaged upholstery and the possibility of the
wheelchair tipping forward.
NOTE: Adequate mo ility and upper ody
strength is required to perform this activity
independently. Use of an assistant is strongly
recommended.
1. Position the wheelchair as close as
possible along side the seat to which
you are transferring, with the cast-
ers aligned parallel with the object.
2. Engage motor locks. Refer to the
TDX Owners Manual, part number
111 809. Shift body weight into seat
with transfer.
3. During independent transfer, little or no seat platform will be beneath you. Use a
transfer board if at all possible.
