Interference may occur in the vicinity of
equipment marked with the follow-ing
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.
