Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the “Daylight”,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P80MHzto800MHz
d=2.3√P800MHzto2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufactur-
er and d is the recommended separation
distance in metres (m).
