Recommended separation distances between portable and mobile RF
The d evice is intended for use in an electromagnetic environment in which ra- diated
RF disturbances are controlled. The customer or the user can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
AirForce Mini
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
