Recommended separation distances between portable and mobile
RF communications equipment and the
Liberator
The Liberator is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the Liberator can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Liberator 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 distance (d) in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the trans-
mitter 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.
* This table is included as a standard requirement for equipment which has been tested to specific test levels and over specific frquency
ranges and been found compliant with regulations.
