SECTION 2—EMI INFORMATION
Part No. 1139640 15 Pronto® M61™with SureStep®
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 elec-
tric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to
your powered wheelchair.

SECTION 2—EMI INFORMATION
Pronto® M61™with SureStep® 16 Part No. 1139640
 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. Als , the electr nics used in ur
p wered wheelchair can generate a l w level f electr magnetic interference,
which h wever will remain within the t lerances permitted by law.
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;
4) Be aware that adding access ries r c mp nents, r m difying the p wered
wheelchair, may make it m re susceptible t EMI (NOTE: There is n easy way
t evaluate their effect n the verall immunity f the p wered wheelchair); and
5) Rep rt all incidents f unintended m vement r brake release t the p wered
wheelchair manufacturer, and n te whether there is a s urce f EMI nearby.
Imp rtant Inf rmati n
1) 20 v lts per meter (V/m) is a generally achievable and useful immunity level
against EMI (as f May 1994) (the higher the level, the greater the pr tecti n);
2) The immunity level f the pr duct is unkn wn.
M dificati n f any kind t the electr nics f this wheelchair as manufactured by
Invacare may adversely affect the RFI immunity levels.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
Part No. 1139640 17 Pronto® M61™with SureStep®
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. 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
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
NOTE: For this information, refer to FIGURE 3.1.
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 to traverse up to a 5 cm 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.

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 N V R 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.
