Ⅵ.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 modification of any form to the power wheelchair is allowed, including adding or
removing any parts.
