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 1 UT is the a.c. mains voltage prior to application of the test level.
NOTE
2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
NOTE 3: Over the frequency range 150kHz to 80 MHz, field strengths should be less than 3 V/m.
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
can
not be predicted theoretically with accuracy. To assess the electrom
agnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the
system
is used exceeds the applicable RF compliance level
above, the
system should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the system.
