Recommended separation distances between portable and mobile RF
communications equipment and the Guardian Link
The Guardian Link is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the Guardian Link users can
help prevent electromagnetic interference by maintaining a minimum distance be-
tween portable and mobile RF communications equipment and the Guardian Link as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance d in meters (m) can be estimated using the equation applicable to the frequency of the transmit-
ter, where p is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
Note:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
