3. EMI
3. Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM) radios.
Attention
Other types of hand-held devices, such as cordless phones, laptop
computers, AM/FM radios, TV sets, CD players, and small appliances such
as electric shavers and hair dryers are not, so far as we know, likely to
cause EMI problems to your power chair.
Power Chair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the
transmittingantenna(source),theEMfieldsfromhand-heldradiowavesources
(transceivers) are of special concern. It is possible to unintentionally bring high levels
of EM energy very close to the control system of the power chair while using these
devices.Thiscanaffectpowerchairmovementandbraking.Therefore,thewarnings
listed below are recommended to prevent possible interference with the control system
of the power chair.
Warnings
1. Do not operate hand-held transceivers-receivers, such as citizens band (CB) radios,
or turn ON personal communication devices such as mobile phones, while the
power chair 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 power chair OFF as
soon as it is safe;
4. Be aware that adding accessories or components, or modifying the power chair,
may make it more susceptible to EMI (Note: There is no easy way to evaluate
theireffectontheoverallimmunityofthepowerchair).
5. Report all incidents of unintended movement or brake release to the power
chair 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.
