EMI/RFI WARNINGS
Laboratory tests performed by the Food and Drug Administration (FDA) have shown that radio waves can cause
unintended motion of electric scooters. Radio waves are a form of electromagnetic energy (EM). When electromag-
netic 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 know about EMI/RFI. Use this information to minimize the risk that
EMI/RFI will adversely affect your Legend.
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). Because EM is more intense
closer to transmitting antennas (sources of emission), the EM fields from two-way radios are of special concern to
electric scooter users.
If EMI/RFI affects my Legend, 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 Legend.
n The location of your Legend (whether it is on the level ground or on an incline).
n Whether or not your Legend 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 motion of
my Legend?
Unfortunately, EMI/RFI may be difficult to recognize, since 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 the scooter’s 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 inadvertent motion of your Legend is to make certain that you or someone else
is not the cause of the unintended motion.
n Turn off your Legend by removing the key from the key switch when you are getting on or off of your Legend.
n Never leave the key in the key switch of an unattended Legend.
n By following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the throttle
control levers and causing the Legend 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.
