V. Electromagnetic Interference Warning
The power wheelchair may be affected by electromagnetic interference (EMI),
which may cause damage or interruption to the operation of the chair. It is
important for you to understand the instructions which can help you take
protective measures against the risk of interference.
The sources of electromagnetic waves come from broadcasting stations, TV
stations, radio transmitters, two-way radios (such as walkie-talkies), cellular
phones and computers. Interference from these electromagnetic waves may
cause malfunction or permanent damage to the chair’s braking and control
system.
CAUTION!
1. The power wheelchair has passed the 30 V/m EMI test and has a certain
degree of immunity to most common electromagnetic energy sources.
However, it is important for you to follow the safety guidelines as follows:
a. Do not turn on or operate portable transceivers, receivers, radios or
any wireless communication devices.
b. Stay away from all radio wave emission sources.
2. If interference does occur and causes unintended movement to
the chair in an uncontrolled manner, cut off the power immediately.
3. No modi fication of any form to the power wheelchair is allowed,
including adding or removing any parts.
