Portable and mobile RF
communications equipment should be
used no closer to any part of the
ClosureRFG radiofrequency generator,
including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d=1.2 √P
d=1.2 √P 80 MHz to 800 MHz
d=2.3 √P 800 MHz to 2.5 GHz
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
metres (m).
Field strengths from fixed RF

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