WARNING: RADIO WAVE SOURCES MAY AFFECT POWERED CHAIR CONTROL
Radio wave source, such as radio stations, TV stations, amateur radio (HAM) transmit-
ters, two-way radios, and cellular phones, can affect powered wheelchairs.
Following the warning listed below should reduce the chance of unintended brake re-
lease or powered wheelchair movement, which could result in serious injury.
1. Do not turn ON hand-held personal communication devices, such as citizens band
(CB) radios and cellular phones, while the powered wheelchair is turned ON;

close to them;
3. If unintended movement or brake release occurs, turn the powered wheelchair OFF
as soon as it is safe;
4. Be aware that adding accessories or components, or modifying the powered
wheelchair, may take it more susceptible to interference from radio wave sources
(Note: There is no easy way to evaluate their effect on the overall immunity to powered
wheelchair); and
5. Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a radio wave source nearby.
IMPORTANT EMI INFORMATION
