Monitor, including cables, than the
recommended separation distance

applicable to the frequency of
the transmitter. Recommended
separation distance.
80 MHz to 800 MHz
800 MHz to 2.5 GHz
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

, 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 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 reflection from
structures, objects and people.
