of the wheelchair. It is important to practice and master
thesesafetechniquesuntilyouarecomfortableinmaneu-
vering around the frequently encountered architectural
barriers.
Usethisinformationonlyasa“basic”guide.Thetechniques
thatarediscussedonthefollowingpageshavebeenused
successfully by many.
Individual wheelchair users often develop skills to deal
with daily living activities that may differ from those de-
scribed in this manual. Invacare recognizes and encour-
ageseach individualto try what works bestfor him/herin
overcomingarchitecturalobstaclesthattheymayencoun-
ter,however, ALL WARNINGSandCAUTIONS givenin

are a starting point for the new wheelchair user and as-
sistant with “safety” as the most important consideration
for all.
Stability and Balance
WARNING
ALWAYS wear your seat positioning strap.
To assure stability and proper operation of your wheel-
chair,youmustatalltimesmaintainproperbalance.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 main-
tain stability and balance.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, re-
member to use good body mechanics. Keep your back
straight and bend your knees whenever tilting wheel-
chair or traversing curbs, or other impediments.
Also, be aware of detachable parts such as arms or leg-
rests. These must NEVER be used for hand-hold or lift-
ing supports, as they may be inadvertently released, re-
sulting in possible injury to the user and/or assistant(s).
When learning a new assistance technique, have an
experiencedassistanthelpyoubeforeattemptingitalone.
Stairways

WARNING
CAUTION: IT ISVERY 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 electromag-
netic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) trans-
mitters, 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 morecommon sources of radiated EMI. This powered
wheelchair model as shipped has an unknown immunity level.
There are a number of sources of relatively intense electromagnetic fields in the everyday environ-
ment. Some of these sources are obvious and easy to avoid. Others are not apparent and exposureis
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. **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-rangetransmittersand transceivers,suchascommercialbroadcast transmitters(radioand
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.

13
WARNING
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 brak-
ing. 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) Donotoperatehand-heldtransceivers(transmittersreceivers),suchas citizens band(CB)radios,
orturnON personalcommunicationdevices,such ascellularphones,whilethepoweredwheel-
chair 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 MCC MKIV controller for this application has an unknown immunity level.
Modification of any kind to the electronics of this wheelchair as manufactured by Invacare may
adversely affect the RFI immunity levels.
