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 meters (m).
Field strengths from xed 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.
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 reected from structures, objects and people.
