SECTION 2—EMI INFORMATION
SECTION 2—EMI INFORMATION
 WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION
REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC
INTERFERENCE ON YOUR POWERED WHEELCHAIR.
Electr magnetic Interference (EMI) Fr m Radi Wave S urces
P wered wheelchairs and m t rized sc ters (in this text, b th will be referred t
as p wered wheelchairs) may be susceptible t electr magnetic interference (EMI),
which is interfering electr magnetic energy (EM) emitted fr m s urces such as
radi stati ns, TV stati ns, amateur radi (HAM) transmitters, tw way radi s, and
cellular ph nes. The interference (fr m radi wave s urces) can cause the p wered
wheelchair t release its brakes, m ve by itself, r m ve in unintended directi ns. It
can als permanently damage the p wered wheelchair's c ntr l system. The
intensity f the interfering EM energy can be measured in v lts per meter (V/m).
Each p wered wheelchair can resist EMI up t a certain intensity. This is called its
"immunity level." The higher the immunity level, the greater the pr tecti n. At this
time, current techn l gy is capable f achieving at least a 20 V/m immunity level,
which w uld pr vide useful pr tecti n fr m the m re c mm n s urces f radiated
EMI.
There are a number f s urces f relatively intense electr magnetic fields in the
everyday envir nment. S me f these s urces are bvi us and easy t av id.
Others are n t apparent and exp sure is unav idable. H wever, we believe that by
f ll wing the warnings listed bel w, y ur risk t EMI will be minimized.
The s urces f radiated EMI can be br adly classified int three types:
1) Hand-held P rtable transceivers (transmitters-receivers with the antenna
m unted directly n the transmitting unit. Examples include: citizens band (CB)
radi s, "walkie talkie", security, fire and p lice transceivers, cellular teleph nes,
and ther pers nal c mmunicati n devices).
NOTE: Some cellular telephones and similar devices transmit signals while they are ON,
even when not being used.
2) Medium-range m bile transceivers, such as th se used in p lice cars, fire trucks,
ambulances and taxis. These usually have the antenna m unted n the utside f
the vehicle; and
3) L ng-range transmitters and transceivers, such as c mmercial br adcast
transmitters (radi and TV br adcast antenna t wers) and amateur (HAM)
radi s.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers,
M/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.

SECTION 2—EMI INFORMATION
Part No. 1123839 17
 WARNING
P wered Wheelchair Electr magnetic Interference (EMI)
Because EM energy rapidly bec mes m re intense as ne m ves cl ser t the
transmitting antenna (s urce), the EM fields fr m hand-held radi wave s urces
(transceivers) are f special c ncern. It is p ssible t unintenti nally bring high
levels f EM energy very cl se t the p wered wheelchair's c ntr l system while
using these devices. This can affect p wered wheelchair m vement and braking.
Theref re, the warnings listed bel w are rec mmended t prevent p ssible
interference with the c ntr l system f the p wered wheelchair.
Electr magnetic interference (EMI) fr m s urces such as radi and TV stati ns,
amateur radi (HAM) transmitters, tw -way radi s, and cellular ph nes can affect
p wered wheelchairs and m t rized sc ters.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD REDUCE THE
CHANCE OF UNINTENDED BRAKE RELEASE OR POWERED WHEELCHAIR
MOVEMENT WHICH COULD RESULT IN SERIOUS INJURY.
1) D n t perate hand-held transceivers (transmitters receivers), such as citizens
band (CB) radi s, r turn ON pers nal c mmunicati n devices, such as cellular
ph nes, while the p wered wheelchair is turned ON;
2) Be aware f nearby transmitters, such as radi r TV stati ns, and try t av id
c ming cl se t them;
3) If unintended m vement r brake release ccurs, turn the p wered wheelchair
Off as s n as it is safe;

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 3—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 skills to deal with daily living activities that
may differ from those described in this manual. ProBasics 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 alance
 WARNING
ALWAYS wear y ur seat p siti ning strap.The seat p siti ning strap is a
p siti ning belt nly. It is n t designed f r use as a safety device withstanding high
stress l ads such as aut r aircraft safety belts. If signs f wear appear, belt MUST
be replaced immediately.
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 walking beam allows you to traverse up to a 2-inch 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 wheelchair is 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 in.

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.
lso, 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.
Tipping
 WARNING
DO NOT tip the wheelchair with ut assistance.
When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a
non-removable (non-detachable) part. Inform the wheelchair occupant before tipping the
wheelchair and remind him/her to lean back. Be sure the occupant’s feet and hands are
clear of all wheels.
Tipping - Curbs
fter mastering the techniques of tipping the wheelchair, use this procedure to tackle
curbs, short stairs, etc.
This procedure requires two assistants. The second assistant should be positioned at the
front of the wheelchair lifting upward on a non-removable (non-detachable) part of the
wheelchair frame when lifting the wheelchair and stabilizing the wheelchair when the
wheelchair is being lowered to the ground.
The first assistant should turn the anti-tippers so the wheels are pointing up, apply a
continuous downward motion until the balance point is achieved and the front casters
clear the curb. t this point, the assistants will feel a difference in the weight distribution.
