ELECTROMAGNETIC INTERFERENCE
AND WARNINGS

CAUTION: It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your power chair.
Powered wheelchairs and otoried scooters ay e suscetile to electroagnetic
intererence EMI which is interering electroagnetic energy EM eitted ro sources
such a radio stations V stations aateur radio M transitters two-way radios and
cellular hones he intererence ro radio wave sources can cause the otoried
scooter to release its rakes ove y itsel or ove in unintended directions It can also
eranently daage the otoried scooter control syste he intensity o the interering
EM energy can e easured in volts er eter V Each otoried scooter can resist
EMI u to a certain intensity his is called its iunity level he higher the iunity
level the greater the rotection will e t this tie current technology is caale o
achieving at least a 2 V iunity level which would rovide useul rotection ro
the ore coon sources o radiated EMI he iunity level o this otoried scooter
odel is 2 V
here are a nuer o sources o relatively intense electroagnetic ields in the everyday
environent Soe o these sources are ovious and easy to avoid thers are not
aarent and eosure is unavoidale owever we elieve that y ollowing the warnings
listed elow your risk to EMI will e iniied
Some cellular telephones and similar devices transmit signals while
they are ON, even when not being used.
The sources of radiated EMI can be broadly classified into three types：
1and-held ortale transceivers transitters-receivers with the antenna ounted
directly on the transitting unit Eales include citiens and CB radios walkie
talkie security ire and olice transceivers cellular telehones and other ersonal
counication devices
2Mediu-range oile transceivers such as those used in olice cars ire trucks
aulances and tais hese usually have the antenna ounted on the outside o
the vehicle

SEREN
3ong-range transitters and transceivers such as coercial roadcast transitters
radio and V roadcast antenna towers and aateur M radios
Because EM energy raidly ecoes ore intense as one oves closer to the transitting
antenna source the EM ields ro hand-held radio wave sources transceivers are o
secial concern It is ossile to unintentionally ring high levels o EM energy very close
to the ower chair control syste while using these devices his can aect ower chair
oveent and raking hereore the warnings listed elow are recoended to revent
ossile intererence with the control syste o the ower chair
Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, and 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 motorized scooter.
Power Chair Electromagnetic Interference：
Electroagnetic intererence EMI ro sources such as radio and V stations aateur
radio M transitters two-way radios and cellular hones can aect the ower chair
Following the warnings listed elow should reduce the chance o unintended rake release
or ower chair oveent which could result in serious inury
1Do not oerate hand-held transceivers transitters-receivers such as citiens and
CB radios or turn N ersonal counication devices such as cellular hones
while the ower chair is turned N

as it is sae
Be aware that adding accessories or coonents or odiying the ower chair ay
ake it ore suscetile to EMI and
Reort all incidents o unintended oveent or rake release to the distriutor listed
on the inside ront cover o this anual Note whether there is a source o EMI neary
