SECTION 2—EMI INFORMATION
Pronto® M71™ 6 Part No 1118377
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 1118377 7 Pronto® M71™
 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;
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) This device has been tested t a radiated immunity level f 20 v lts per meter;
3) 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 EMI immunity levels.
