should be used not closer to
any part of the device, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2.5 GHz
Where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and
d
is the recommended separation
distance in meters (m).

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.
