Portable and mobile RF
communications equipment should
be used no closer to any part of the
Maxi Air
system including cables,
than the recommended separation
distance calculated from the
equation applicable to the frequency
of the transmitter.
Recommended separation distance
d=1,2 √ P
d=1,2 √ P 80 MHz to 800 MHz
d=2,3 √ P 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)
Field strengths from 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
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 absorp-
tion and reflection from structures, objects and people.
