Portable and mobile RF communications
equipment should be used no closer to any part
of the UP-27MD, including cables, than the
recommended separation distance calculated
from the equation appliance to the frequency of
the transmitter.

Where is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
