Portable and mobile RF communications equipment should
be used no closer to any part of the device, including cables,
than the recommended separation 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 separation distance
in meters (m)b.
Field strengths from fixed RF transmitters, as determined by
an electromagnetic site surveyc, should be less than the
compliance level in each frequency range d
Interference may occur in the vicinity of equipment marked
with the following symbol: .
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
