1. The higher frequency range applies at 80 MHz and 800 MHz.
2. 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. An investigation of the
location is recommended to determine the electromagnetic
environment resulting from stationary HF transmitters. 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 unusual
performance characteristics are observed, it may be necessary to
take additional measures such as reorientation or repositioning of
the UNIT.
3. Over the frequency range 150kHz to 80MHz, field strengths should
be less than 3V/m.
