Portable and mobile RF communications
equipment should be used no closer to any part
of the Aaron 940, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with the
following symbol.
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 Aaron 940 is used exceeds the applicable RF compliance level above, the Aaron 940
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Aaron 940™.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
