a
Field strengths from fixed transmitters, such as base stations for radio (mobile/wireless)
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-orientating or
relocating the System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
