offers greater protection. In other words, a power chair with a high immunity level is less likely to be affected
by a strong radio source than one with a low immunity level.
What is the FDA doing about the problem?
The FDA has written power chair manufacturers and requested that they test their new products to be sure that
they provide a reasonable degree of immunity against EMI/RFI. The letter states that power chairs should
have an immunity of at least 20 V/m. This provides a reasonable degree of protection against the common
sources of EMI/RFI.
The FDA has also requested that these manufacturers clearly label their products with the immunity level, or
state that the immunity level is not known. The labeling and informational material supplied with the power
chair must explain what the immunity level means, and the labeling or informational material must warn
users about the possibility of EMI/RFI and how to avoid it. In addition, the FDA has recommended that
manufacturers establish an educational program to inform power chair users and their caregivers about the
problems associated with EMI/RFI, and the actions they can take to minimize the risk. The FDA requested
that power chair manufacturers have these actions implemented by December 2, 1994.
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 1105 meets
or exceeds an immunity level of at least 20 V/m.
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. For example, if you are in a power chair with an immunity level of 20
V/m, you should remain at least three feet from a hand-held two-way radio and ten feet from a mobile
two-way radio.
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. There is no easy way to evaluate their effect on the
overall immunity of the power chair.
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.
If my power chair moves unexpectedly, where should I report this?
Call Pride at 1-800-824-8205 to report the incident.
