Conducted RF

Radiated RF
IEC 61000-4-3
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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
predicated 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 which the A1250™ is used exceeds the applicable RF compliance level above, the A1250™
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the A1250™.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the A1250™, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
