III. EMI/RFI
What is the FDA doing about the problem?
The FDA has written to the manufacturers of electric scooters and requested that those manufacturers test
their new models of scooters to be certain that they provide a reasonable degree of resistance against EMI/
RFI. The FDA has stated that all newly manufactured models of electric scooters should have a resistance
level of at least 20 V/m. This level of resistance provides a reasonable degree of protection against the
common sources of EMI/RFI.
The FDA has also requested or recommended that:
n Electric scooter manufacturers clearly label new products with that products resistance level or state
that the resistance level is not known.
n The labeling or informational material supplied with new electric scooters must explain what the re-
sistance level means and warn users about the possibility of EMI/RFI and how to avoid it.
n Manufacturers of electric scooters undertake an educational program to inform the users of electric
scooters and the caregivers of those users about the problems associated with EMI/RFI and about the
actions the users and caregivers can take to minimize the risk of EMI/RFI.
n While there is no exact way to tell if your scooter is totally safe, an immunity level of 20 V/m (May
1994) is achievable. This product has been tested and passed at an immunity level of 20 V/m. Adding
accessories and components or modifying the unit may change the susceptibility to EMI/RFI.
What can I do to find out if my Shuttle is likely to be affected by EMI/RFI?
If you have had your Shuttle for some time and have not experienced any unintended motion, it is not likely
that you will have a problem in the future. However, it is always possible that EMI problems could arise if
you are close to a source of radio waves. Therefore, it is very important for you to be alert to this possibility.
The Shuttle meets or exceeds a resistance level of at least 20 V/m.
What can I do to reduce the risk of my Shuttle being affected by EMI/RFI?
Here are some precautions you can take:
n Do not turn on or use hand-held personal communications devices, such as citizens band (CB) radios
and cellular phones, while your Shuttle is turned on.
n Be aware of nearby radio wave transmitters, such as radio or TV stations and hand-held or mobile two-
way radios. Try not to operate your Shuttle too close to those transmitters. For example, if you are on
an electric scooter 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.
n Be aware that adding accessories and/or components, or modifying your Shuttle in any way may change
its EMI/RFI resistance level and may make it more susceptible to interference from radio wave sources.
What should I do if my Shuttle moves unexpectedly?
If unintended motion or unintended brake release occurs, turn off your Shuttle (by removing the key) as
soon as it is safe to do so.
If my Shuttle moves unintentionally, where should I report the incident?
Call our headquarters at (570) 655-5574 to report the incident.
