EMI/RFI WARNINGS
Laboratory tests performed by the Food and DrugAdministration (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 affectstheoperationofanelectricaldevice,thatadverseeffectiscalled Electro- magnetic Interference (EMI) or Radio Frequency Interference (RFI).
EMI/RFI FREQUENTLY ASKED QUESTIONS (FAQS)
ThefollowingFAQssummarizewhatyoushouldknowaboutEMI/RFI.Usethisinformationtominimizetherisk thatEMI/RFIwilladverselyaffectyourmobilityvehicle.
Where do radio waves come from?
Radio waves are emitted from the antennas of cellular phones, mobile
If EMI/RFI affects my mobility vehicle, what kind of motion should I expect?
This is difficult to predict. The answer would depend on a number of factors:
νThe strength of the radio waves.
νTheconstructionofyourparticularmobilityvehicle.
νThe location of your mobility vehicle (whether it is on level ground or on an incline).
νWhetherornotyourmobilityvehicleisinmotion.
The motion of any electric mobility vehicle affected by EMI/RFI can be erratic. The mobility vehicle 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 mobility vehicle. Some intense EMI/RFI can even damage the control system components of an electric mobilityvehicle.
Is there any way to know for certain whether or not radio waves are the cause of any unintended mobility vehicle motion?
Unfortunately,EMI/RFImaybedifficulttorecognize,becausethesignalsfromradiosourcesareinvisibleandmay be intermittent. However, the FDArecommends that you report all incidents of unintended motion or unintended brake release of your mobility vehicle 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 mobility vehicle is to make certain that you or someone else is not the cause of the unintended motion.

νNever leave the key in the key switch of an unattended mobility vehicle.
νBy following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the throttle controlleversandcausingthemobilityvehicletomoveunintentionally.
Has anyone been injured by the erratic, unintended motion of an electric mobility vehicle?
The FDA has reports of injuries that resulted from uncontrolled motion of electric mobility vehicles, but it is not clear just how many of those injuries were actually caused by EMI/RFI.
