structures, objects, and people.
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 device is used exceeds the applicable RF compliance level above, the device should be observed
to verify normal operation. If abnormal 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, the field strengths should be less than 3 V/m.
