ELECTROMAGNETIC INTERFERENCE (EMI)
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) ma be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energ (EM) emitted
from sources such as radio stations, TV stations, amateur radio (HAM)
transmitters, two wa radios, and cellular phones. The interference (from
radio wave sources) can cause the powered wheelchair to release its brakes,
move b itself, or move in unintended directions. It can also permanentl
damage the powered wheelchair's control s stem. The intensit of the
interfering EM energ can be measured in volts per meter (V/m). Each
powered wheelchair can resist EMI up to a certain intensit . This is called its
"immunit level." The higher the immunit level, the greater the protection.
At this time, current technolog is capable of achieving at least a 20 V/m
immunit level, which would provide useful protection from the more
common sources of radiated EMI. This powered wheelchair model as shipped,
MKIV - RII electronics, has an immunit level of unknown.
There are a number of sources of relativel intense electromagnetic fields in
the ever da environment. Some of these sources are obvious and eas to
avoid. Others are not apparent and exposure is unavoidable. However, we
believe that b following the warnings listed, our risk to EMI will be minimized.
SECTION 1 GENERAL GUIDELINES
GENERAL GUIDELINES

Part No. 1118362 Rev A Power Tilt Only For M71 and M91.
ELECTROMAGNETIC INTERFERENCE (EMI)
The sources of radiated EMI can be broadl classified into three t pes:
1) Hand-held Portable transceivers (transmitters-receivers with the
antenna mounted directl on the transmitting unit. Examples include:
citizens band (CB) radios, "walkie talkie," securit , fire, And police
transceivers, cellular telephones, and other personal communication
devices. **NOTE: Some cellular telephones and similar devices transmit
signals while the 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 usuall 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, D 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.
GENERAL GUIDELINES SECTION 1
GENERAL GUIDELINES

Power Tilt Only For M71 And M91. 2 Part No.1118362 Rev A
POWERED WHEELCHAIR ELECTROMAGNETIC INTERFERENCE (EMI)
Because EM energ rapidl 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
unintentionall bring high levels of EM energ ver close to the powered
wheelchair's control s stem 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
s stem of the powered wheelchair.
Electromagnetic interference (EMI) from sources such as radio and TV
stations, amateur radio (HAM) transmitters, two-wa 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
injur .
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 nearb transmitters, such as radio or TV stations, and tr
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 modif ing the
powered wheelchair, ma make it more susceptible to EMI (Note:
There is no eas wa to evaluate their effect on the overall immunit
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 nearb .
IMPORTANT INFORMATION
1) 20 volts per meter (V/m) is a generall achievable and useful immunit
level against EMI (as of Ma 1994) (the higher the level, the greater the
protection);
2) The immunit level of this product is unknown.

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 s ills to deal with daily living activities that may differ
from those described in this manual. Invacare recognizes and encourages each individual to try
what wor s 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 our seat positioning strap.
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.
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.
While the wal ing beam allows to traverse up to a 2-inch (M71) or a 3-inch (M91) bump or
threshold, stopping after the wheels cross the bump poses a problem. The chair cannot reverse
over the bump at this point. Continue forward and then turn around.
While the M91 and M71 are designed for use
primarily in and around the home, the provider
should determine whether this chair is suitable
for the actual environment the chair will be
used.
Do not go down ramp at full speed. Some seat/back
positions will cause wheelchair to feel unstable.
CAUTION
Be aware of condition of ramp.
Traction will be diminished/
nonexistent on a slipper surface.
Proceed with caution.
GENERAL GUIDELINES SECTION 1

Power Tilt Only For M71 And M91. 4 Part No.1118362 Rev A
A NOTE TO WHEELCHAIR ASSISTANTS
When assistance to the wheelchair user is required, remember to use good body mechanics.
Keep your bac straight and bend your nees whenever tilting wheelchair or traversing
curbs, or other impediments.
Also, be aware of detachable parts such as arms or the footboard. 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.
LIFTING/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 ONLY secure, nondetachable parts for hand-hold supports.
It is strongly recommended to lift the wheelchair only by the rear frame and
the front forks - otherwise injury or damage 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 base with batteries and without the user is 3 8 lbs.
Use proper lifting techniques (lift with your legs) to avoid injury.
Follow this procedure for moving the wheelchair between floors when an elevator is NOT
available or lifting the wheelchair is necessary:
NOTE: When using a stairwa to move the wheelchair, seat and an accessories, move all wheelchair
components awa from the stairwa prior to reassembl .
1. Remove the occupant from the wheelchair.
2. Remove the front riggings and any accessories.
3. Bend your nees and eep your bac straight.
4. Using the rear frame and the front edge of the front for s as hand hold supports, transfer
the wheelchair base to desired location.
5. Using non-removable (nondetachable)
parts, transfer the seat and any accesso-
ries to desired location.
6. Reassemble the wheelchair.

TRANSFERRING TO AND FROM OTHER SEATS
WARNING
ALWAYS turn the wheelchair power OFF and engage the Motor Release
Levers 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 by aligning both the front AND 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 activit ma be performed independentl provided ou have adequate mobilit and upper
bod 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. After the wheelchair is positioned
properly for transfer, verify that the
Motor Release Levers are engaged.
Refer to ENGAGING/DISENGAG-
ING MOTOR RELEASE LEVERS in
the owner's manual shipped with
wheelchair.
3. Flipbac or remove arm on side of
wheelchair you are transferring
from.
4. Shift body weight into seat with transfer.
During independent transfer, little or no seat platform will be beneath you. Use a transfer
board if at all possible.
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 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, reach-
ing and transferring activities in several combinations in the presence of a
qualified healthcare professional BEFORE attempting active use of the wheel-
chair.
Proper positioning is essential for your safety. When reaching, leaning, bend-
ing or bending forward, it is important to use the casters as a tool to maintain
stability and balance.
