EMI WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular telephones can affect powered wheelchairs. Following the
warnings listed below should reduce the chance of unintended brake release or powered wheelchair
movement which could result in serious injury.
WARNING: Do not operate hand-held transceivers (transmitters-receivers), such as citi-
zens band (CB) radios, or turn on personal communication devices, such as
cellular telephones, while the powered wheelchair is turned on.
WARNING: Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them.
WARNING: If unintended movement or brake release occurs, turn the powered wheel-
chair off as soon as it is safe.
WARNING: Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more susceptible to EMI (Note: There is no easy
way to evaluate their effect on the overall immunity of the powered wheel-
chair).
WARNING: Report all incidence of unintended movement or brake release to Graham-
Field Health Products, and note whether there is a source of EMI nearby.
IMPORTANT INFORMATION
1) 20 volts per meter (V/m) is a generally achievable and useful immunity level against EMI (as of May
1994) (the higher the level, the greater the protection);
2) is powered wheelchair model has an immunity level of 20 V/m.
Be aware that using different components, adding accessories, or modifying the powered wheelchair may
change the immunity level.
