NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reection from structures,
objects and people.
a Field strengths from xed RF transmitters, such as base stations for
radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic
environment due to xed RF transmitters, an electromagnetic site
survey should be considered. If the measured eld strength in the
location in which device is used exceeds the applicable RF complian-
ce level above, device should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating device.
b Over the frequency range 0.15 MHz to 80 MHz, eld strengths should
be less than 3 V/m.
Recommended separation distances between
portable and mobile RF communications equipment and device
The device is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user
of device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equi-
pment (transmitters) and device, as recommended below, according to the
maximum output power of the communications equipment.
