Portable and mobile RF communications equipment
should be used no closer to any part of the system,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.

Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
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 1: At 80MHz and 800MHz, 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 fixe
d transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
can not 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 system is used exceeds the applicable RF compliance
level above, the system should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or relocating the system.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
