Compliance
Electromagnetic environment – guidance
Level
Power frequency magnetic fields should be at levels characteristic of a typical
location in a typical domestic, commercial or hospital environment .
Portable and mobile RF communications equipment should be used no closer
to any part of the System, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the
transmitter .

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
metres (m) .
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
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 (mobile/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 reorientating or relocating the
System .
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m .
a should be less than the compliance level in each frequency range . b
