The hearing protectors, and especially the
pads, may deteriorate with use and so should
regularly be checked for tear and leaks.
If the hearing protectors are damaged or
worn, they will not provide the expected
protection, and they must therefore not
be used any longer. Replace or repair the
hearing protectors.
Check the hearing protectors thoroughly for
wear and tear before each use.
Placing hygienic covers onto the pads may
affect the acoustic function of the hearing
protection.
Check that the hearing protectors are
correctly positioned regularly during use
in order to ensure they are providing the
optimum protection.
The use of hearing protectors with or
without the entertainment function may
make it harder to hear warning signals in the
workplace.
Never use in traffic.
The hearing protectors must not be exposed
to direct sunlight for long periods, as this
may deform them.
The output of the electric audio circuit of the
earmuffs may exceed the daily sound level
limit.
The earmuffs provide an audio signal sound
pressure level limitation and the hearing
protectors limit the intertaintment audio
signal to 82 dB(A) effetive to the ear.
EN352-6 specifies that the input voltage
should result in 82 dBA (mean plus one
standard deviation, (SD)). The input level
required was calculated to be 92.3 (rounded
to 92) mV.
For the EN352-8 testing, the same eight
human subjects were tested. The 18102
28
earmuffs were set to maximum transmission
volume. The following table presents the
measurement results.
The mean+standard deviation level must not
exceed 82 dBA. Therefor, the 18102 earmuffs
passes this test.

Use
1. Extend the headband before use, Place
the ear cups over each ear, make sure the
microphone in the forward position to
obtain the best listening condition.
2. Adjust the headband by sliding the
headband up or down to the fit position.
3. The ear cushions should seal the ear
firmly against the head. For best results,
remove all hair under the cushion, noise
reduction will be adversely effected by
anything that impairs the seals of the
earmuff cushions against the head, such
as thick spectacle frames, hats, etc.
