Portable and mobile RF communications equipment
should be used no closer to any part of the AC-120MD,
including cables, than the recommended separation
distance calculated from the equation appliance 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 and
d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

be less than the compliance level in each frequency
range.

Interference may occur in the vicinity of equipment
marked with following symbol:
IEC 61000-4-3 80 MHz to 2.7 GHz
NOTE 1: At 80 MHz and 800 MHz, 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.
