communications equipment
should be used no closer to any
part of the models Fi-G, including
cables, than the recommended
separation distance calculated
from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d=1.2×P1/2
d=2×P1/2
d=1.2×P1/2 80 MHz to 800 MHz
d=2.3×P1/2 800 MHz to 2.7 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
the following symbol:
NOTE I At 80 MHz end 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.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength
in the location in which the model Fi-G is used exceeds the applicable RF
compliance level above, the model Fi-G should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the model Fi-G.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3V/m.
