a. Field strengths from fi xed 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 fi xed RF
transmitters, an electromagnetic site survey should be considered. If the
measure fi eld strength in the location in which the Receiver is used exceeds
the applicable RG compliance level above, the Receiver should be observed
to verify normal operation. If abnormal performance is observed, additional
measures may be necessary such as reorienting or relocating the Receiver.
b. Over the frequency range 150 KHz to 80 MHz, fi eld strengths should be less
than 3 V/m.
