in watts (W) according to the
transmitter manufacturer and
d
is the recommended separation
distance in metres (m).

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.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
