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:
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 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 re-orienting or relocating the System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
