Compliance Electromagnetic Environment Guidance
Level
Portable and mobile RF communications equipment
should be used no closer to any part of the Receiver,
including cables than the recommended separation
distance calculated from the equation applicable to
the frequency of the 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
