used no closer to any
part of the 2 Face /
Face Evolution (Model:
2 Face / Face
Evolution), including
cables, than the

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.
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).
Field strengths from
fixed RF transmitters,
