Long-range transmitters and transceivers, such as commercial broadcast transmitter
(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 players, and cassette players and small appliances, such
as electric shavers and hair dryers, are not likely to cause EMI problems to your
powered vehicle.

ELECTRIC POWERED VEHICLE ELECTROMAGNETIC INTERFERENCE
(EMI)
Because EM energy rapidly becomes more intense as you 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 closer to the powered vehicle’s control system while using
these devices. This can affect powered vehicle movement and braking. 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
electric powered vehicles and motorized scooters. Following the warnings listed
below should reduce the chance of unintended brake release or electric powered
vehicle movement that could lead to 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 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 electric powered vehicle
OFF as soon as it is safe.
4.
Be aware that adding accessories or components, or modifying the electric powered
vehicle, may make it more susceptible to EMI (Note: There is no easy way to
evaluate their effect on the overall immunity of the powered vehicle).
5.
Report all incidents of unintended movement or brake release to the electric
powered vehicle to the manufacturer, and note whether there is a source of EMI
nearby.

IMPORTANT INFORMATION
1.
20 Volts per meter (V/m) is generally an acceptable immunity level against EMI
(The higher the level, the greater the protection). This product has an immunity level
of 20 V/m without any accessories connected to it.
