Guidance and Manufacturer's Statement – Recommend Separation Distance
between portable and mobile RF communications equipment and the
Model AR-8305
Recommended separation distances between portable and mobile RF communications
equipment and the ModelAR-8305
The ModelAR-8305 Synergy Resection System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
Model AR-8305 can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Model AR-8305 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 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.
