Portable and mobile RF communications equipment should
be used no closer to any part of the model
WPC-765/WPC-765E , including cables, than the
recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1,2
d = 1,2 80 MHz to 800 MHz
d = 2,3 800 MHz to 2,5 GHz
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.
