EMI/RFI WARNINGS
Laboratory tests performed by the Food and Drug Administration (FDA) have shown that radio waves can
cause unintended motion of electric mobility vehicles. Radio waves are a form of electromagnetic energy
(EM). When electromagnetic energy adversely affects the operation of an electrical device, that adverse
effect is called Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI).
EMI/RFI FREQUENTLY ASKED QUESTIONS (FAQS)
The following FAQs summarize what you should kn ow about EMI/RFI. Use this information to minimize the
risk that EMI/RFI will adversely affect your Scooter.
Where do radio waves come from?
Radio waves are emitted from the antennas of cellular phones, mobile two-way radios (such as walkie-
talkies and CBs), radio stations, TV stations, amateur radio (HAM) transmitters, wireless computer links,
microwave sources, and paging transmitters. Radio waves are a form of electromagnetic energy (EM). EM
is more intense closer to transmitting antennas, which are sources of emission. The greater the transmission
strength, the greater the concern to electric mobility vehicle users.
If EMI/RFI affects my Scooter, what kind of motion should I expect?
This is difficult to predict. The answer would depend on a number of factors:
n The strength of the radio waves.
n The construction of your particular Scooter.
n The location of your Scooter (whether it is on the level ground or on an incline).
n Whether or not your Scooter is in motion.
The motion of any electric Scooter affected by EMI/RFI can be erratic. The Scooter may come to a sudden
stop or move in an uncontrolled manner. Also, it is possible for EMI/RFI to release the brakes of an electric
Scooter. Some intense EMI/RFI can even damage the control system components of an electric Scooter.
Is there any way to know for certain whether or not radio waves are the cause of any unintended Scooter
motion?
Unfortunately, EMI/RFI may be difficult to recognize, because the signals from radio sources are invisible
and may be intermittent. However, the FDA recommends that you report all incidents of unintended motion
or unintended brake release of your electric Scooter to its manufacturer and, if possible, determine whether
or not there was a radio wave source nearby at the time of the incident.
One precaution you can take against unintended motion of your Scooter is to make certain that you or
someone else is not the cause of the unintended motion.
n Turn off your Scooter by removing the key from the key switch when you are mounting or dismounting
your Scooter.
n Never leave the key in the key switch of an unattended Scooter.
n By following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the
throttle control levers and causing the Scooter to move unintentionally.
Has anyone been injured by the erratic, unintended motion of an electric Scooter?
The FDA has reports of injuries that resulted from uncontrolled motion of electric Scooters, but it is not
clear just how many of those injuries were actually caused by EMI/RFI.
