Are all electric mobility vehicles susceptible to EMI/RFI?
Each make and model of electric mobility vehicle differs in its ability to resist EMI/RFI. Every mobility
vehicle has a particular level of resistance to EMI/RFI. This resistance is measured in volts per meter (V/
m). A higher resistance level offers greater protection against EMI/RFI. In other words, an electric mobility
vehicle with a high resistance level is less likely to be affected by a strong radio source than is an electric
mobility vehicle with a low resistance level.
What is the FDA doing about the problem?
The FDA has written to electric mobility vehicle manufacturers and requested that those manufacturers test
their new mobility vehicle models to be certain that they provide a reasonable degree of resistance against
EMI/RFI. The FDA has stated that all newly manufactured electric mobility vehicle models should have a
resistance level of at least 20 V/m. This level of resistance provides a reasonable degree of protection
against the common sources of EMI/RFI.
The FDA has also requested or recommended that:
n Electric mobility vehicle manufacturers clearly label new products with their resistance level or state
that the resistance level is not known.
n The labeling or informational material supplied with new electric mobility vehicles must explain what
the resistance level means and warn users about the possibility of EMI/RFI and how to avoid it.
n Electric mobility vehicle manufacturers undertake an educational program to inform electric mobility
vehicle users and their caregivers about the problems associated with EMI/RFI and about the actions
they can take to minimize the risk of EMI/RFI.
n While there is no exact way to tell if your mobility vehicle is totally safe, an immunity level of 20 V/m
is generally achievable and useful. This product has been tested and passed at an immunity level of 20 V/m.
What can I do to find out if my mobility vehicle is likely to be affected by EMI/RFI?
If you have had your mobility vehicle for some time and have not experienced any unintended motion, it is
not likely that you will have a problem in the future. However, it is always possible that EMI/RFI problems
could arise if you are close to a source of radio waves. Therefore, it is very important for you to be alert to
this possibility. The mobility vehicle meets or exceeds a resistance level of at least 20 V/m.
What can I do to reduce the risk of my mobility vehicle being 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 your mobility vehicle is turned on.
n Be aware of nearby radio wave transmitters, such as radio or TV stations and hand-held or mobile two-
way radios. Try not to operate your mobility vehicle too close to those transmitters. For example, if you
are on an electric mobility vehicle with a resistance level of at least 20 V/m, you should remain at least
three feet from a hand-held two-way radio and at least ten feet from a mobile two-way radio.
n Be aware that adding accessories and/or components, or modifying your mobility vehicle in any way,
may change its EMI/RFI resistance level and may make it more susceptible to interference from radio
wave sources.
What should I do if my mobility vehicle moves unexpectedly?
If unintended motion or unintended brake release occurs, turn off your mobility vehicle (by removing the
key) as soon as it is safe to do so.
If my mobility vehicle moves unintentionally, where should I report the incident?
Call Pride Customer Care at 1-800-424-8205 to report the incident.
