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).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
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 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 relocating the System.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
