device, including cables, than the recommended separation distance calculated from the equat-
ion applicable to the frequency of the transmitter.

transmitter manufacturer and d is the recommended separation 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.
