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 AX-C4343W is used exceeds the applicable RF compliance level above, the
AX-C4343W should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the AX-C4343W.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
