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, and electromagnetic site survey should be
considered. If the measured field strength in the location in which the System is used exceeds
the applicable RF compliance level above, the System should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocation the System.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Note : These guidelines may not apply in all situations. Electromagnetic propagation is affected
