Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection by structures, objects
and people.
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 unit is used exceeds the applicable RF compliance level above, the unit
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
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.
