■ POWERED VEHICLE ELECTROMAGNETIC INTERFERENCE (EMI)
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 closer to the powered vehicle's vehicle
movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of
the powered vehicle control system while using these devices. This can
affect powered
■ 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 wheelchair. Following
the warnings listed below should reduce the 39 40 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); and 25
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,
