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;
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 ( Note: There is no easy way to evaluate their effect on the overall immunity
of the powered scooter ).
5. Report all incidents of unintended movement or brake release to the powered scooter manufacturer,
and note whether there is a source of EMI nearby.

2.4.4 IMPORTANT INFORMATION

1. 20 Volts per Metre (V/m) is a generally achievable and useful immunity level against EMI (the
higher the level, the greater the protection);
2. This product has an immunity level of 20 V/m without any accessories connected to it.
