Portable and mobile RF communications
equipment should be used no closer to any part
of the model WMP-153, including cables, than
the recommended separation distance
calculated from 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 and
d
is the
recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
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.
