Guidance and manufacture´s declaration – electromagnetic immunity
The Audiometer 9910
is intended for use in the electromagnetic environment specified below. The customer or the
user of the Audiometer 9910
should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any part
of the Audiometer 9910, including cables, than the

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 meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a 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 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 Audiometer 9910 is used exceeds the applicable RF compliance level
above, the Audiometer 9910 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Audiometer 9910.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m
