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

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.
