Finding Recommended Separation Distances
In the following table, 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).
Portable and mobile RF communications equipment should be used no closer to any part of the
device, including cables, than the recommended separation distance calculated from the equation
appropriate for the frequency of the transmitter.
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 this symbol:
