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, field strengths
should be less than [Vi] V/m.
