Where P is the maximum output power
rating of the transmitter in watts
(W) according to the transmitter
manufacturer and d is the
recommended separation distance in
meters (m).

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