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