Portable and mobile RF communications equipment should be used
no closer to the Lady-Comp devices and are calculated including
the line utilized as the recommended minimum distance, per the
equation applicable to the transmission frequency. Recommended
separation distance:
d = [3.5/3]√P = 1.2√P
d = [3.5/10]√P = 0.35√P
for 80 MHz to 800 MHz
d = [7.0/10]√P = 0.7√P
for 800 MHz to 2.5 GHz
where P is the power rating of the transmitter in watts (W) according
to the transmitter manufacturer and d is the recommended separa-
tion distance in meters (m). The field strength of stationary radio
transmitters should be in accordance with a site survey, less than
the compliance level in each frequency range. Interference is pos-
sible in the vicinity of equipment marked with the following symbol.
