Note: UT is the AC mains voltage prior to application of the test level.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
a)
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.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
