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 consid-
ered. If the measured field strength in the location in which the model POC-W242 is used
exceeds the applicable RF compliance level above, the model POC-W242 should be
observed to verify normal operation. If abnormal performance is observed, additional mea-
sures may be necessary, such as reorienting or relocating the model POC-W242.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
