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:
νDo not turn on or use
νBe aware of nearby transmitters such as radio or TV stations and
νBe aware that adding accessories and/or components or modifying the power chair may make it more susceptible to interference from radio wave sources.
νThere 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 you’ve had your power chair for a long time and haven’t 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 FDAhas 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?
