Recommended separation distances between portable and mobile RF
The Guardian 2 Link is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the Guardian 2 Link users
can help prevent electromagnetic interference by maintaining a minimum distance be-
tween portable and mobile RF communications equipment and the Guardian 2 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.
