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
CAUTION! Interference may occur in the vicinity of equipment marked with the following symbol:
4
Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: 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 RF 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 V3404 Plus is used exceeds the applicable RF transmitter compliance level above, the V3404 Plus should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the V3404 Plus.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
