Owner´s manual Chairman Playman Important information
3.
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
computers, AM/FM radios, TV sets, CD players, and casette players, and small
appliances, 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
braking. Therefore, the warnings listed below are recommended to prevent
possible 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
listed below should reduce the chance of unintended brake release or
powered wheelchair movement which could result in serious injury.
1.
Do not operate hand-held transceivers (transmittersreceivers), such as citizens
band (CB) radios, or turn ON personal communications devices, such as
cellular 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.
