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 product is used exceeds the applicable RF compliance level above, the product should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
