150 KHz to 80 MHz
Not applicable
Portable and mobile RF communications equipment should be
used no closer to any part of the FLG-351,
FEG-113,FEG-123,FEG-115
including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
NOTE1:
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2:
These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from
structures, objects and people
.
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
FLG-351, FEG-113,FEG-123
,FEG-115
should be observed to verify normal operation. If
abnormal performance is observed, additional measures
my be necessary, such as re-orienting or relocating the
FLG-351, FEG-113,FEG-123,FEG-115.Over the frequency
range 150 kHz to 80 MHz, field strengths should be les
than 3 V/m.

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).
Interference may occur in the vicinity of
equipment marked with the following symbol:
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey , should be less than the compliance level in
each frequency range .
