Electromagnetic Interference Warning ............................................. continued
Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna
(source) , the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is pos-
sible to unintentionally bring high levels of EM energy very close to the control system while using these
devices.
WARNING!: The warnings listed below are recommended to prevent possible interference
with the control system of the power positioning system.
Do not turn on personal communications devices, such as cellular phones, or operate hand-
held transceivers (transmitters, receivers), such as citizens band (CB) radios, while the pow-
ered wheelchair is turned on.
Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close
to them
If unintended movement occurs, turn the wheelchair off as soon as it is safe to do so.
Be aware that adding accessories or components, or modifying the power positioning sys-
tem may make it more susceptible to EMI. Note: There is no easy way to evaluate their effect
on the overall immunity of the powered wheelchair.
Report all incidents of unintended movement of the power positioning system to the manu-
facturer, and note whether there is a source of EMI nearby.
CAUTION! Modification of any kind to the electronics of the power positioning system as
manufactured by Motion Concepts may adversely affect the radio frequency interference
immunity (RFI) levels.
