• Are all powerchairs susceptible to EMI?
Each make and model differs in its ability to resist electromagnetic interference. Each has a
particular level of "immunity" to interference measured in volts per meter (V/m). The higher the
immunity levels the greater the protection. In other words, a powerchair with a high immunity level
is less likely to be affected by an intense radio source than one with a low immunity level.
If you want to find out how well your powerchair is protected against EMI, you can contact the
manufacturer and inquire about its immunity level.
• What can I do to reduce the risk that my powered powerchair could be affected by EMI?
Here are some precautions you can take:
1. Do not turn ON or used hand-held personal communication devices, such a cellular phones or
citizens band (CB) while the powered LIBERTY™ 624 MINI is ON.
2. Be aware of nearby transmitters, such as TV stations or radio and hand-held or mobile two-way
radios, and try to avoid coming close to them. For example, a powered LIBERTY™ 624 MINI
with an immunity level of 20V/m should stay at least three feet from a hand-held, two-way radio
and ten feet from a mobile two-way radio.
3. Be aware that adding accessories or components, or modifying the powered LIBERTY™ 624
MINI may make it more susceptible to interference from radio wave sources. (Note: There is
no easy way to evaluate their effect on the overall immunity of the powered LIBERTY™ 624
MINI.)
• What should I do if my powered LIBERTY™ 624 MINI moves unexpectedly?
If untended motion or brake release occurs, turn the LIBERTY™ 624 MINI OFF as soon as it is
safe.
• If my powered LIBERTY™ 624 MINI moves unexpectedly, where should I report this?
You should report the incident to:
The manufacturer and/or distributor, and FDA's MedWatch problem reporting program. Call 1-800-
FDA-1088 and ask for Form 3500.
