survey, (a) should be less
than the compliance level
in each frequency range
(b)
Interference may occur in
the vicinity of equipment
marked with the following
symbol:
NOTE1 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.
