3.2 The three sources of radiated EMI
3.2.1 Hand-held portable transceivers (transmitter-receivers) with the antenna
mounted directly on the transmitting unit, such as citizens band (CB) radios,
walkie-talkies, security and fire or police transceivers, cellular telephones and
other personal communication devices;
SUGGESTION
●
Some cellular telephones or similar devices transmit signals while they are
ON, even though they are not in use.
3.2.2 Medium-range mobile transceivers used in police cars, fire trucks, ambulances
and taxis usually having the antenna mounted on the outside of the vehicle;
and
3.2.3 Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM)
radios.
SUGGESTION
●
Other types of hand-held devices (cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, cassette players, and small appliances
such as electric shavers and hair dryers, et cetera) so far as we know, are not
likely to cause EMI problems.
3.3 Powered Vehicle 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 too close to the powered vehicle's control system while using
these devices. This can affect your powered vehicle's movement and braking.
Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered vehicle.
