Portable and mobile RF
communications equipment should
be used no closer to any part of the
Micro 1, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation
distance
d = 1.2 x √P
d = 1.2 x √P 80MHz to 800MHz
d = 2.3 x √P 800MHz to 2.5GHz
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 metres (m).
Field strengths from a fixed RF
transmitters as determined by an
electromagnetic site 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:
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.
