NOTE:
Other types of hand-held devices (cordless phones, laptop computers, AM/FM radios, TV
sets, CD players, cassette players, and small appliances such as electric shavers and hair
dryers, et cetera) so far as we know, are not likely to cause EMI problems.
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 too close to
the powered vehicle's control system while using these devices. This can affect your powered
vehicle's 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 wheelchairs. Following the warnings listed below should reduce the chance of
unintended brake release or powered vehicle movement that 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 stay away from
them.
3. If unintended movement or brake release occurs, turn the powered vehicle OFF as soon as
it is safe.
CAUTION:
Some stores may have automatic (sensor) doors and alarm systems set at certain frequencies
that might affect your power wheelchair.
4. Be aware that adding accessories/components or modifying the powered vehicle may make
it more susceptible to EMI. 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 your powered vehicle
dealer or KARMA, and note whether there was 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 is, the greater the protection will be.)
2. This product has an immunity level of 20 V/m without any accessories connected to it.
