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 equat-
ion applicable to the frequency of the transmitter.
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
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 fi xed RF transmitters, as determined by an electromagnetic site survey,
a should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
