These guidelines may not apply in all
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. lf the measured field strength in the location in which the Device is used exceeds the applicable RF compliance level above, the Device
should be observed to verify normal operation. If normal performance is observed, additional measures may be necessary, such as reorienting or relocating the Device. b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [Vii V/m].
