Transport - Wheelchair Tie-Down Restraints and Seat Restraints (TRRO or TRBKTS)
WARNING
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 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 165 to 300 lbs.
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.
Battery support brackets MUST be installed at all times. Otherwise, the wheelchair will not be WC19 compliant. Refer to
Transport Ready Option (TRRO)

Stairways and Escalators
WARNING
Follow this procedure for moving the wheelchair between floors when an elevator is NOT available:
1. Remove the occupant from the wheelchair.
2. Remove the batteries from wheelchair. Refer to Batteries on page 76.
3. Bend your knees and keep your back straight.
4. 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.
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 independently of the power wheelchair.
Extreme caution is advised when it is necessary to move an unoccupied power wheelchair up or down the stairs. Invacare
recommends using two assistants and making thorough preparations. Make sure to use ONLY secure, non-detachable
parts for hand-hold supports.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.
DO NOT attempt to lift the wheelchair by any removable (detachable) parts. Lifting by means of any removable (detachable) parts of a wheelchair may result in injury to the user or damage to the wheelchair.
The weight of the wheelchair without the user and without batteries is between 220 and 300 lbs. Use proper lifting techniques (lift with your legs) to avoid injury.
When using a stairway to move the wheelchair and any accessories, move all wheelchair components away from the stairway prior to reassembly.

2 SAFETY
2.2 Safety/Handling
“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.
Users and assistants must be aware that the handling and maneuverability characteristics of front wheel drive wheelchairs are inherently different from
center and rear wheel drive wheelchairs. Handling and maneuverability differences will be most noticeable when traveling down declines (Example:
ramps and slopes) or over obstacles and rough terrain as this may shift the users center of mass forward resulting in decreased stability. ALWAYS
reduce speed and wear the seat positioning strap when driving under these conditions.
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.
Invacare strongly recommends that initial use of front wheel drive wheelchairs be supervised by an assistant.
WARNING
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.

2 SAFETY
WARNING
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tilting wheelchair or traversing curbs or other impediments.
Also, be aware of detachable parts such as arms or legrests. These must NEVER be used to move the wheelchair or as 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.
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.
DO NOT attempt to stop a moving wheelchair with the wheel locks. Wheel locks are not brakes.
DO NOT engage or disengage the motor locks until the power is in the off position.

Stability and Balance
WARNING
ALWAYS wear your seat positioning strap. 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.
The drive behavior initially experienced by the user may be different from other wheelchairs previously used. The following warnings apply specifically when using this front wheel drive wheelchair.
• 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.
• ALWAYS traverse down ramps at a reduced, constant speed to maintain stability and to avoid hard braking or sudden
stops.
• The end user’s weight can materially affect traction on sloped surfaces. Great care should be taken when traversing such
slopes.
ALWAYS reduce speed when traveling up or down an incline or over obstacles and rough terrain. Traveling under these conditions may shift the users weight forward resulting in reduced stability.
Exercise caution and avoid sudden stops when traveling up or down an incline or over obstacles and rough terrain. If
stopping becomes necessary under these driving conditions, release the joystick and allow the wheelchair to come to a full
stop. Then proceed at a slower speed.
DO NOT traverse down ramps at high speed. Doing so will reduce traction and increase stopping distance.

Weight Training
WARNING
Weight Limitation
Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus. Invacare wheelchairs have
NOT been designed or tested as a seat for any kind of weight training. If occupant uses said wheelchair as a weight training
apparatus, INVACARE SHALL NOT BE LIABLE FOR BODILY INJURY AND THE WARRANTY IS VOID.
WARNING
2.3 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.
Refer to Technical Data on page 33 to determine the weight limit (total combined weight of user and any attachments) of your wheelchair model. DO NOT exceed the limit - otherwise, injury or damage may result.
Part No 1163181
27 Invacare® FDX®
2 SAFETY
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).
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.
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.
Some cellular telephones and similar devices transmit signals while they are ON, even when not being used.
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.
Invacare® FDX®
28 Part No 1163181
2 SAFETY
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 wheelchair as manufactured by Invacare may adversely affect the EMI immunity levels.

5 WHEELCHAIR OPERATION
Using the Joystick to Drive the Wheelchair
The joystick is located on the joystick housing and provides smooth control of speed and direction. It is equipped with 360 degrees of mobility for
ease of operation. The joystick is spring-loaded, and automatically returns to the upright (neutral) position when released. Pushing the joystick in a
given direction causes the wheelchair to move in that direction.
The joystick has proportional drive control, meaning that the further it is pushed from the upright (neutral) position, the faster the wheelchair moves. The maximum speed, however, is limited by the setting of the speed-control knob.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has automatic speed and direction compensation to minimize corrections.
When first learning to drive, select a slow speed and try to drive the wheelchair as slowly as possible by pushing the joystick slightly forward. This
exercise will help you learn to utilize the full potential of the proportional control and allow you to start and stop smoothly.
To drive the wheelchair, perform the following:
1. Adjust speed control knob to the appropriate setting.
2. Turn the power On. Refer to Turning the Power On/Off
3. Maneuver the joystick in the following manner:

5.6 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 front of the joystick.
DO NOT sit in the wheelchair while charging the batteries.
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.
5 WHEELCHAIR OPERATION
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.
Part No 1163181
For this procedure, refer to FIGURE12 on page 55.
New batteries MUST be fully charged prior to initial use of the wheelchair.
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.
53 Invacare® FDX®
5 WHEELCHAIR OPERATION
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 or enter a trickle charge mode to maintain the batteries depending on charger model.
There are some basic concepts which will help you understand this automatic process. They are:
Once the charger has been connected to the wheelchair and wall outlet and, if necessary, the charger has been turned on, the battery charger indicator
lights will flash and light to show the battery charger status and condition of batteries to be charged. Refer to owner’s manual shipped with battery
charger.
WARNING
NEVER leave the charger unattended when the breaker has tripped. A fault condition exists. Unplug and discontinue using immediately. Contact an Invacare dealer.
Invacare® FDX®
If performing the charging procedures, READ and CAREFULLY follow the individual instructions for each charger (supplied or purchased).
If charging instructions are not supplied, consult a qualified service technician for proper procedures.

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.
5 WHEELCHAIR OPERATION
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.
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.
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.

WARNING
The angle of the pelvic belt should be 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.
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 frontal crash. Steeper angles will
reduce 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.
