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.
3) Long-range transmitters and transceivers such as commercial
broadcast transmitters (radio and TV broadcast antenna towers)
and amateur (HAM) radios.
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.
Powered Scooter 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 scooter’s control system while using these devices.
This can effect powered scooter movement and braking. Therefore,
the warnings listed below are recommended to prevent possible
interference with the control system of the motorized scooter.
