Portable and mobile RF communications
equipment should be used no closer to
any part of the SD5/SD6 , 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.
