EMI
37
There are a number of sources of relatively intense
electromagnetic fields in the everyday environment.
Some of these sources are obvious and easy to avoid.
Others are not apparent and exposure is unavoidable.
However, we believe that by following the warning listed
below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly
classified into three types:
1. Hand-held portable transceivers (transmitter-
receivers with the antenna mounted directly on the
transmitting unit). Examples include: citizens band
(CB) or hand held radios,(security, fire, and police
transceivers), cellular telephones and other personal
communication devices.
NOTE: some cellular telephones transmit a
signal while they are ON, even though they are
not being used.
2. Medium-range mobile transceivers, such as those
used in police cars, fire trucks, ambulances and taxis
usually have the antenna mounted on the outside of
the vehicle.
3. Long-range transmitters and transceivers, such as
commercial broadcast transmitters (radio and TV
broadcast antenna towers) and amateur (HAM) radios.
NOTE: Other types of hand-held devices, such as
cordless phones, laptop computers, AM/FM
radios, TV sets, CD player, and cassette players,
and small appliances, such as electric shavers
and hair dryers, are not likely to cause EMI
problems to your powered wheelchair.
