product, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

P
is the maximum output power rating of the
transmitter in watts (W) according to the transmit-

ration distance in meters (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.
