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