SAFETY NOTICE
3. 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 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 scooter.
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 ( transceivers ) are of
special concern. It is possible to unintentionally bring high levels of EM energy very close
to the control system of powerchair 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 scooter.
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 scooter
and motorized scooter. 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 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 and connected
to it.
