unavoidable.
However, we believe that by following the warning listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
1. Hand-held portable transceivers (transmitter-receivers with the antenna mounted directly on the
transmitting unit). Examples include: citizens band (CB) radios, “walkie talkies”, security, fire, and
police transceivers, mobile telephones and other personal communication devices.
Attention:
Some mobile telephones and similar devices transmit signals 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
3. Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and TV
broadcast antenna towers) and amateur (HAM) radios.
Attention:
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 scooter.

2.4.2 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 control system of the
scooter while using these devices. This can affect powered scooter movement and braking. Therefore,
the warnings listed below are recommended to prevent possible interference with the control system of
the powered scooter.
2.4.3 WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and mobile phones can affect powered scooters. Following the warnings
listed below should reduce the chance of unintended brake release or powered scooter 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 mobile phones, while the powered scooter is turned ON;
2. Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to them;
