Portable and mobile RF
communications equipment
should be used no closer to
any part of the device, including
cables, than the recommended
separation distance calculated

the frequency of the transmitter.

Field strengths from fixed RF
transmitters, as determined
by an electromagnetic site
survey,
a
should be less than
the compliance level in each
frequency range.
b
Interference may occur In the
vicinity of equipment marked
with the following symbol:
NOTE I At 80 MHz end 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 are used exceeds
the applicable RF compliance level above, the model 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 150 kHz to 80 MHz, field strengths should be less
than 3V/m.
