Are all PMVs susceptible to EMI/R I?
Each make and model of electric PMV differs in its ability to resist EMI/RFI. That is, each PMV has a articular
level of resistance to EMI/RFI. This resistance is measured in volts er meter (V/m). A higher resistance level offers
greater rotection against EMI/RFI. In other words, an electric PMV with a high resistance level is less likely to be
affected by a strong radio source than is an electric PMV with a low resistance level.
What is the DA doing about the problem?
The FDA has written to electric PMVs manufacturers and requested that those manufacturers test their new
models of PMVs to be certain that they rovide a reasonable degree of resistance against EMI/RFI. The FDA has
stated that all newly manufactured models of electric PMVs should have a resistance level of at least 20 V/m. This
resistance level rovides a reasonable degree of rotection against the common sources of EMI/RFI.
The DA has also requested or recommended that:
nElectric PMV manufacturers clearly label new roducts with that roducts resistance level or state that the
resistance level is not known.
nThe labeling or informational material su lied with new electric PMVs must ex lain what the resistance level
means and warn users about the ossibility of EMI/RFI and how to avoid it.
nElectric PMV manufacturers undertake an educational rogram to inform electrical PMV users and their
caregivers about the roblems associated with EMI/RFI and about the actions they can take to minimize the
risk of EMI/RFI.
nWhile there is no exact way to tell if your PMV is totally safe, an immunity level of 20 V/m (May 1994) is
generally achievable and useful. Adding accessories and com onents or modifying the unit may change the
susce tibility to EMI/RFI.
What can I do to find out if my Wrangler is likely to be affected by EMI/R I?
If you have had your Wrangler for some time and have not ex erienced any unintended motion, it is not likely that
you will have a roblem in the future. However, it is always ossible that EMI roblems could arise if you are close
to a source of radio waves. Therefore, it is very im ortant for you to be alert to this ossibility. The Wrangler PMV
meets or exceeds a resistance level of at least 20 V/m.
What can I do to reduce the risk of my Wrangler being affected by EMI/R I?
Some recautions are:
nDo not turn on or use hand-held ersonal communications devices, such as citizens band (CB) radios and
cellular hones, while your Wrangler is turned on.
nBe aware of nearby radio wave transmitters, such as radio or TV stations and hand-held or mobile two-way
radios. Try not to o erate your Wrangler too close to those transmitters. For exam le, if you are on an electric
PMV with a resistance level of at least 20 V/m, you should remain at least three feet from a hand-held two-way
radio and at least ten feet from a mobile two-way radio.
nBe aware that adding accessories and/or com onents, or modifying your Wrangler in any way, may change its
EMI/RFI resistance level and may make it more susce tible to interference from radio wave sources.
What should I do if my Wrangler moves unexpectedly?
If unintended motion or unintended brake release occurs, turn off your Wrangler (by removing the key) as soon as
it is safe to do so.
If my Wrangler moves unintentionally, where should I report the incident?
