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
SwitchPoint Infinity® 3 Control System is used exceeds the applicable RF compliance
level above, the SwitchPoint Infinity® 3 Control System should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the SwitchPoint Infinity® 3 Control System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/
m.
