Portable and mobile RF communications
equipment should be used no closer to
any part of the device, including cables,
than the recommended distance
calculated from the equation applicable
to the frequency of the transmitter.

Where
P
is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer, and
d
is the recommended
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.
