EMI/RFI WARNINGS
Laboratory tests performed by the Food and DrugAdministration (FDA) have shown that radio waves can cause unintended motion of electric PMVs. 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 Wrangler.
Where do radio waves come from?
Radio waves are emitted from the antennas of cellular phones, mobile
If EMI/RFI affects my Wrangler, 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 Wrangler.
νThe location of your Wrangler (whether it is on level ground or on an incline).
νWhether or not your Wrangler is in motion.
The motion of any electric PMV affected by EMI/RFI can be erratic. The PMV 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 PMV. Some intense EMI/RFI can even damage the control system components of an electric PMV.
Is there any way to know for certain whether or not radio waves are the cause of any unintended motion of my Wrangler?
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 PMV to the PMV’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 Wrangler is to make certain that you or someone else is not the cause of the unintended motion.
νTurn off your Wrangler by removing the key from the key switch when you are getting on or off of your Wrangler.
νNever leave the key in the key switch of an unattended Wrangler.
By following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the throttle control levers and causing the Wrangler to move unintentionally.
Has anyone been injured by the erratic, unintended motion of an electric PMV?
The FDA has reports of injuries that resulted from uncontrolled motion of electric PMVs, but it is not clear just how many of those injuries were actually caused by EMI/RFI.
