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.

Commonly Asked Questions

•

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.)
