2. SAFETY NOTICE
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, so far as we know, are not likely to cause EMI problems to your powered vehicle.
■ POWERED VEHICLE 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 ( transreceivers) are of special concern. It
is possible to unintentionally bring high levels of EM energy very closer to the powered vehicle’s
control system while using these devices. This can affect powered vehicle movement and braking.
Therefore, the warnings listed below are recommended to prevent possible interference with the
control system of the powered vehicle.
■ WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio
(HAM) transmitters, two-way radios, and cellular phones can affect powered vehicles and motorized
scooter. Following the warnings listed below should reduce the chance of unintended brake release or
powered vehicle 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 cellular phones, while the powered vehicle 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 vehicle OFF as soon as it is safe;
4. Be aware that adding accessories or components, or modifying the powered vehicle, may make it
more susceptible to EMI ( Note: There is no easy way to evaluated their effect on the overall
immunity of the powered vehicle);
5. Report all incidents of unintended movement or brake release to the powered vehicle manufacturer,
and note whether there is a source of EMI nearby;
■ IMPORTANT INFORMATION
1. 20 Volts per meter ( 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.
