Chapter 2 System Setup
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 POC-W211 is used exceeds
the applicable RF compliance level above, the POC-W211 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be nec-
essary, such as reorienting or relocating the unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
