Note 1: From 80 MHz to 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
a: Field strengths from fixed 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 fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the device is used exceeds
the applicable RF compliance level above, the device should be observed to
verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the device.
b: Over the frequency range from 1 50kHz to 80MHz, field strengths should be
less than 3V/m.

radiated RF disturbance are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the device as recommended below, according
to the maximum output power of the communication equipment.
