Long-range transmitters and transceivers, such as commercial broadcast
transmitter (radio and TV broadcast antenna tower) and amateur (HAM) radios.
NOTE! Other types of hand-held devices, such as cordless phones, laptop com-
puters, AM/FM radios, TV sets, CD players, and casette players, and small appli-
ances, such as electric shavers and hair dryers, so far we know, are not likely to
cause EMI problems to your powered wheelchair.
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 powered wheelchair's control system while
using these devices. This can affect powered wheelchair movement and bra-
king. Therefore, the warnings listed below are recommended to prevent possi-
ble interference with the control system of the powered wheelchair.
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 wheelchairs and motorized scooters. Following the warnings lis-
ted below should reduced the chance of unintended brake release or powered
wheelchair movement which could result in serious injury.
1.
Do not operate hand-held transceivers (transmitters/receivers), such as citizens
band (CB) radios, or turn ON personal communications devices, such as cellu-
lar phones, while the powered wheelchair 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 wheelchair
OFF as soon as it is safe.
4.
Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more susceptible to EMI.
(Note: There is no easy way to evaluate their effect on the overall immunity of
the powered wheelchair).
5.
Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a radio wave source nearby.
