Powered Chair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense the closer one moves 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
the Powerchair’s movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of the
Powerchair.
WARNINGS
The following warnings listed below should reduce the chance of unintended brake
release or Powerchair movement, which could result in serious injury.
1. Do not operate hand-held transceivers (transmitter-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 powered
chair.
Report all incidents of unintended movement or brake to your Powerchair provider, and
note whether there are sources of EMI nearby.
NOTE: The Shark controller EMI rating is FDA Regulated and conforms to federal
regulations.
