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 wheel-
chairs) 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. This powered wheelchair model as shipped has an unknown immunity level.
6
PROCEDURE 1GENERAL GUIDELINES
WARNING
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 appar ent 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 thr ee 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.
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.
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) The controllers for this application have unknown immunity levels.
Modification of any kind to the electronics of this wheelchair as manufactured by Invacare may adversely affect the RFI immunity levels.

“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.
I
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
I
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
AL WAYS wear your seat positioning strap.
Stairways
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
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 (2) assistants and making thorough preparations. Make sure to use ONL Y 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 wheelchair 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:
WARNING
The weight of the wheelchair without the user and
batteries is still between 140 and 168 lbs. Use proper
lifting techniques (lift with your legs) to avoid injury.
1. Remove the occupant from the wheelchair.
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.
2. Remove the battery boxes from the wheelchair. ReINSTALLING/REMOVING BATTERY BOXES
fer to
in PROCEDURE 11 of this manual.
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.
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 stability and balance.
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
A Note to Wheelchair Assistants
between floors. Serious bodily injury may occur.
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 for hand-hold 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.

GENERAL GUIDELINES PROCEDURE 1
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 BEFORE attempting to transfer in or out of the wheelchair. Also, make sure
every precaution is taken to reduce the gap distance aligning both rear 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: This activity may be performed independently
provided you have adequate mobility and upper body
strength.
1. Position the wheelchair as close as possible along
side the seat to which you are transferring, with the
rear casters pointing away from it.
2. Engage motor locks/clutches. Refer to one (1) of the
following.

8 of this manual.
ENGAGING/DISENGAGING
Percentage of Weight Distribution
W ARNING
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 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 rear casters as a tool to maintain stability and balance.
Functional Reach From a Wheelchair
The approximate reach-limit values shown in the accompanying graphs were derived on the basis of a sample of
91 male and 36 female wheelchair users. Note the difference between the maximum and the comfortable reach
limits, a subjective but important consideration in design.

ies. If the caps of battery cells are removed,
NEVER look directly into them when charging battery.
The use of rubber gloves and safety glasses is recommended when testing the battery cells.
When reading a hydrometer, DO NOT allow any
liquid to come in contact with your eyes or skin. It
is a form of acid and can cause serious burns,
and in some cases, blindness. If you do get battery acid on you, flush the exposed areas with
cool water IMMEDIATELY. If the acid comes into
contact with eyes or causes serious burns, get
medical help IMMEDIATELY.
The battery acid can damage your wheelchair,
clothing, and household items. Therefore, take
readings cautiously and only in designated areas.
ONLY use distilled water when topping of f the
battery cells.
Most batteries are not sold with instructions. However, warnings are frequently noted on the cell
caps. Read them carefully.
1. Remove the battery boxes from the wheelchair. ReINSTALLING/REMOVING BATTERY BOXES
fer to
in PROCEDURE 11 of this manual.
2. Remove the battery caps from the battery.
3. Squeeze the air from the hydrometer.
4. Place the hydrometer into a battery cell.
NOTE: DO NOT fill hydrometer more than 3/4 full.
5. Draw up sufficient acid to cover float balls.
Follow recommendations in this manual when selecting a battery or charger.
Fully charge a new battery before using.
Use a lifting strap to remove, move or install a battery.
ONLY use distilled water to refill.
Keep the liquid level in the cells at the “split ring” level.
Maintain the liquid in all cells at the “split ring” level.
Push battery clamps onto terminals. Spread clamps wider if necessary.
Use ONL Y a GEL charger for a GEL or sealed battery and a regular charger for
regular batteries.
6. Tap lightly to remove air bubbles.
7. Number of floating balls indicates charge.
NUMBER OF FLOA TING BALLS
0 Discharged
1 25% Charged
2 50% Charged
3 75% Charged
4 100% Charged
* 5 Overcharged
* Check charging system.
8. Flush the liquid back into the same cell after reading
the float. Repeat this step until all cells have been
properly read. A shorted or dead cell can be detected
when it is the only cell that doesn’t charge.
9. Flush hydrometer in cold running water by allowing
the water to rise into the hydrometer as far as possible. Do this several times to guard against burn
damage.
10. Replace the battery caps.
11. Install the battery boxes onto the wheelchair. Refer
