Laboratory tests performed by the Food and DrugAdministration (FDA) have shown that radio waves can cause unintended motion of powered wheelchairs. Radio waves are a form of electromagnetic energy (EM). When this energy adversely affects the operation of an electronic device, it is called Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI).

WARNING! Radio waves may interfere with the control of powered wheelchairs.

EMI/RFI—FREQUENTLY ASKED QUESTIONS (FAQS)

The following FAQs summarize what you should know about EMI/RFI. Use this information to minimize the risk that EMI/RFI will affect your power chair.

Where do radio waves come from?

Radio waves are emitted from the antennas of cellular phones, mobile two-way radios (such as walkie-talkies), radio stations, TV stations, amateur radio (HAM) transmitters, wireless computer links, microwave sources, and paging transmitters. Radio waves are a form of EM. Because electromagnetic energy is more intense closer to the transmitting antenna (source of emission), the EM fields from two-way radios are of special concern to power chair users.

If my power chair is affected by EMI/RFI, what kind of motion should I expect? This is hard to predict. It would depend on a number of factors:

νStrength of the radio waves

νConstruction of the power chair

νPosition of the power chair (whether it is on level ground or on an incline)

νWhether or not the power chair is in motion

An affected wheelchair’s movement can be erratic. It may move by itself or come to a sudden stop. Furthermore, it is possible for EMI/RFI to unexpectedly release the brakes on a power chair. Some intense sources of EMI/RFI can even damage the control system of your Jazzy.

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.

Has anyone been hurt from erratic, unintended motion of powered wheelchairs?

The FDA has reports of injuries that resulted from the apparent uncontrolled motion of powered wheelchairs. However, it is unclear how many of these incidents were actually caused by radio wave interference.
