Note:
some cellular telephones and similar transmit signal while they
are ON, even when not being used;
2.
Medium-range mobile transceivers, such as those used in police cars,
fire trucks, ambulances and taxis. These usually have the antenna
mounted on the outside of the vehicle; and
3.
Long-range transmitters and transceivers, such as commercial
broadcast transmitter (radio and TV broadcast antenna towers) and
amateur (HAM) radios.
Note:
Other types of hand-held devices, such as cordless phones,
laptop computers, AM/FM radios, TV sets, CD player, 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
powered vehicle.

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 very
closer to the powered vehicle’s control system while using these
devices. This can affect powered vehicle movement and braking.
Therefore, the warnings listed below are recommended to prevent
possible interference with the control system of the powered vehicle.
■
WARNINGS
Electromagnetic interference (EMI) from sources such as radio and
TV stations, amateur radio (HAM) transmitters, two-way radios, and
cellular phones can affect powered vehicles and motorized
wheelchair. Following the warnings listed below should reduce the
chance of unintended brake release or powered vehicle 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 powered vehicle 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 powered
vehicle
OFF as soon as it is safe;
