Emi - Drive Medical SPGT-3C-BL SPGT-3C-R, SPGT-3C-G Owner's Manual

Attention: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM
radios, TV sets, CD players, cassette and small appliances such as electric shavers and hair dryers
are not likely to cause EMI problems to your powered power chair .
POWERED POWER CHAIR 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 control system
of power chair while using these devices. This can affect powered power chair movement and
braking. Therefore, the warnings listed below are recommended to prevent possible interference with
the control system of the power chair.
WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular phones can affect the power chair. Following the warnings
listed below should reduce the chance of unintended brake release or power chair movement which
could result in serious injury.
1. Do not operate hand-held transceivers-receivers, such as citizens band (CB) radios, or turn ON
personal communication devices such as cellular phones, while the power 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 power chair OFF as soon as it is safe;
4. Be aware that adding accessories or components, or modifying the power chair, may make it more
susceptible to EMI (Note: There is no easy way to evaluate their effect on the overall immunity of
the power chair).
5. Report all incidents of unintended movement or brake release to the power chair 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 ( the
higher the level, the greater the protection);
2. This product has an immunity level of 20 V/m without any accessories and connected to it.
