Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and Receiver
The Receiver is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
Receiver can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the Receiver 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 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
manufacture.
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 refl ection from structures,
objects and people.
