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