Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the device, includ-
ing 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 √P 80MHz~800MHz
d=2.3 √P 800MHz~2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manu-
facturer and d is the recommended
separation distance in metres (m).Field
strengths from xed RF transmitters,
as determined by an electromagnetic
site surveya, should be less than the
compliance level in each frequency
rangeb.
Interference may occur in the vicinity of
equipment marked with the following
