Electromagnetic environment - guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the 790 series
cordless illumination system, including cables, than the
recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
P
d = (1.17)
P
d = (1.17) 80 MHz to 800 MHz
P
d = (2.33) 800 MHz to 2.5 GHz
where P is the maximum output power rating of the
transmitter in watts according to the transmitter
manufacturer and d is the recommended separation
distance in meters.
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
be less than the compliance level in each frequency
