RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
RF COMMUNICATION DEVICE AND THE SYSTEM
The system is intended for use in an electromagnetic environment in which
radiated RF disturbance are controlled. The customer or the user of system can
help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communication equipment (transmitters) and
system as recommended below, according to the maximum output power of the
communication equipment.

For transmitters at a maximum output power not listed above, the recommended separation
distanced in meters (m) can be determined 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.
If system image distortion occurs, it may be necessary to position system further from sources of
conducted RF noise or to install external power source filter to minimize RF noise to an
acceptable level.
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.
