III. EMI/RFI
What can I do to reduce the risk that my power chair could be affected by EMI/RFI?
Here are some precautions you can take:
n Do not turn on or use hand-held personal communications devices such as citizens band (CB) radios and
cellular phones while the power chair is on.
n Be aware of nearby transmitters such as radio or TV stations and hand-held or mobile two-way radios, and try
not to come close to them.
n Be aware that adding accessories and/or components or modifying the power chair may make it more susceptible
to interference from radio wave sources.
n There is no easy way to evaluate their effect upon the overall immunity of the power chair.
What can I do to find out if my power chair is likely to be affected by EMI/RFI?
If youve had your power chair for a long time and havent experienced any unintended motion, it is not likely that
you will have problems in the future. But it is always possible that problems could arise if you are close to a source
of radio waves. Therefore, it is very important to be alert to this possibility. The Jazzy 1113 meets or exceeds an
immunity level of at least 20 V/m.
Is there any way to know for sure whether radio waves are responsible for the unintended motion
of my power chair?
Unfortunately, interference from radio wave sources may be difficult to recognize, since the signals from these
sources are invisible and may be intermittent. However, the FDA recommends that you report all incidents of
unintended motion or brake release to the power chair manufacturer and if possible, note whether there was a
radio wave source nearby at the time of the incident.
What should I do if my power chair moves unexpectedly?
If unintended motion or brake release occurs, turn the power chair off as soon as it is safe to do so.
Has anyone been hurt from erratic, unintended motion of power chairs?
The FDA has reports of injuries that resulted from the apparent uncontrolled motion of power chairs. However, it
is unclear how many of these incidents were actually caused by radio wave interference.
If my power chair moves unexpectedly, where should I report this?
Call Pride Mobility Products Corporation at (570) 655-5574 to report the incident.
