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,
be less than the compliance level in
each frequency range.
Interference may occur in the
vicinity of equipment marked with
the following symbol:
