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 electro- magnetic energy adversely affects the operation of an electrical device, that adverse effect is called Electromag- netic 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 Victory.
Where do radio waves come from?
Radio waves are emitted from the antennas of cellular phones, mobile
If EMI/RFI affects my Victory, 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.
νThe construction of your particular Victory.
νThe location of your Victory (whether it is on level ground or on an incline).
νWhether or not your Victory 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 Victory?
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 Victory is to make certain that you or someone else is not the cause of the unintended motion.
νTurn off your Victory by removing the key from the key switch when you are getting on or off of your Victory.
νNever leave the key in the key switch of an unattended Victory.
By following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the throttle control levers and causing the Victory to move unintentionally.
Are all scooters susceptible to EMI/RFI?
Each make and model of electric scooter differs in its ability to resist EMI/RFI. That is, each scooter 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 scooter with a high resistance level is less likely to be affected by a strong radio source than is an electric scooter with a low resistance level.
