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 At 80 MHz and 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 VisionAire is used exceeds the applicable RF compliance level above, the VisionAire should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the VisionAire.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
