2. Medium-range mobile transceivers, such as those used in police cars, fire
trucks, ambulances and taxis usually have the antenna mounted on the
outside of the scooter.
3. Long-range transmitters and transceivers, such as commercial broadcast
transmitters (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, are not likely to cause EMI
problems to your powered scooter.

POWERED SCOOTER ELECTROMAGNETIC INTERFERENCE (EMI)

EM energy rapidly becomes more intense as one moves closer to a 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 affect your scooters movement and braking. Therefore, the
warnings listed below are recommended to prevent possible interference with the
control system of a powered scooter.
Warning!
Electromagnetic interference (EMI) from sources such as radio and
TV stations, amateur radio (HAM) transmitters, two-way radios, and
cellular phones can affect motorized scooters. Following the warnings
listed below should reduce the chance of unintended brake release or
powered scooter movement which could result in serious injuries.
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 scooter is turned ON.
2. Be aware of nearby transmitters, such as radio or TV stations,
and try to avoid getting close to them.
3. If unintended movement or brake release occurs, turn the
powered scooter OFF as soon as it is safe.
4. Be aware that adding accessories or components, or modifying
the powered scooter, may make it more susceptible to EMI.
5. Report all incidents of unintended movement or brake release to
the scooter manufacturer, and note whether there were sources
of EMI nearby.
