Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
A. Field strengths from fixed RF 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 device is used exceeds the applicable RF
compliance level above, device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating device.
B. Over the frequency range 0.15 MHz to 80 MHz, field strengths should be less than 3 V/m.
