Electromagnetic

calculated from the
equation appropriate for
the frequency of the
transmitter.
Recommended
separation distances:
d=0.35
d=1.2
80MHz to 800MHz:
d=1.2
800MHzto 2.5GHz:
d=2.3
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.
Field strengths from
fixed RF transmitters, as
determined by an
electromagnetic site
survey, should be less
than the compliance
level in each frequency
range. Interference may
occur in the vicinity of
equipment marked with
the following symbol:
