Guidance and manufacturer’s declaration – electromagnetic immunity
The Avant Audiometer is intended for use in electromagnetic environment specific below. The customer or the user of
the Avant Audiometer should assure that it is used in such an environment.
Immunity test
IEC 60601- test level

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

Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency ranges 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 Avant Audiometer is used
exceeds the applicable RF compliance level above, the Avant Audiometer should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Avant Audiometer.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
