2.
Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulance 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 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, cassette players, 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.
Motorized Scooter Electromagnetic Interference:
Because EM energy rapidly becomes more intense as one move 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 motorized scooter control system while using these devices. This can affect motorized
scooter movement and braking. Therefore, the warnings listed below are recommended to
prevent possible interference with the control system of the motorized scooter.
Warnings:
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 motorized scooter movement which could result in serious injury.
1.
Do not operate hand-held transceivers (transmitters-receivers), such as citizens band
(CB) radios, or turn ON personal communication devices, such as cellular phones, while
the motorized scooter 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 motorized scooter OFF as
soon as it is safe;
4.
Be aware that adding accessories or components, or modifying the motorized scooter,
may make it more susceptible to EMI;
There is no easy way to evaluate their effect on the overall immunity of the motorized
scooter.
5.
Report all incidents of unintended movement or brake release to the distributor listed on the
inside front cover of this manual. Note whether there is a source of EMI nearby.
