Field strengths from

transmitters, as determined
by an electromagnetic site

a
, should be less than
the compliance level in each
frequency range. Interference
may occur in the vicinity of
equipment marked with the
following symbol
b
.
Note 1
At 80 MHz and 800 MHz the higher frequency range is essential.
Note 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and re
fl
ection from structures, objects and people.
a
Field strengths from
fi
xed 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
fi
xed RF
transmitters, an electromagnetic side survey should be considered. If the measured
fi
eld strength
outside the location in which the point 2 is used exceeds the compliance level, the point 2 should
be observed to verify normal operation. If abnormal performance is observed, additional measures
my be necessary, such as relocating or using another location of the point 2.
b
Over the frequency range from 150 kHz to 80 MHz the
fi
eld strength should be lower than 3 V/m.
