The sources of radiated EMI can be broadly classified into
three types.
1. Hand-held portable transceivers (transmitters-receivers) with the
antennas mounted directly to the transmitting unit. Examples include:
Citizen band (CB) radios, "walkie-talkie", security, fire, and police
transceivers, cellular telephones and other personal communication
devices. Note: some of the above transmit signals even when they
are not being used for communication.
2. Medium range mobile transceivers, such as those used in police cars,
fire trucks, ambulances and taxis. These usually have the antenna
mounted to the outside of the vehicle; and
3. Long-range transmitters that have the antenna mounted upon
a fixed tower.
Radio Wave sources may affect power wheelchair control.
Radio wave sources, such as radio stations, TV stations, amateur radio
(HAM) transmitters, two-way radios and cellular phones, can affect power
wheelchairs and motorized scooters (in this text, both will be called power
wheelchairs). Following the warnings listed below should reduce the chance
of unintended brake release or power wheelchair movement that could
result in serious injury.

Other types of hand-held devices, such as lap-top
computers, AM/FM receivers, TV sets, CD and cassette
players, and small appliances such as electric shavers
and hair dryers, as far as we know, are not likely to cause
problems to your power wheelchair.
