POWERCHAIR 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 sources
(transceivers) are of special concern. It is possible to unintentionally bring high
levels of EM energy very close to the Powerchair’s control system while using
these devices. This can affect Powerchair movement and braking. Therefore,
the warnings listed below are recommended to prevent possible interference
with the control system of the Powerchair.
WARNINGS
1. Do not operate hand-held transceivers (transmitters-receivers), such as citizens
band (CB) radios, or turn ON personal communication devices, such as cellular
phones, while the Powerchair 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 Powerchair OFF
as soon as it is safe.
4. Be aware that adding accessories or components, or modifying the Powerchair,
may make it more susceptible to EMI.
NOTE! There is no easy way to evaluate the overall immunity of the
Powerchair.
5. Report all incidents of unintended movement or braking to the Powerchair
provider, and note whether there are sources of EMI nearby.
