How to use and take care of my hearing
protector
All hearing protectors, which are included
in this instruction sheet, are equipped with
thermoplastic headband or spring-arms, or
stainless steel neckband and foam-plastic
filled cushions.
Use
To attain highest comfort and protection
from your hearing protector you shall use,
take care of and adjust the protector in
accordance with the instructions below.
- Earmuffs and in particular cushions
may deteriorate with use and should be
examined at frequent intervals for cracking
and leakage, for example. (*2)For hygiene
kit replacement remove the self-adhesive
cushion. Remove the protective film from the
replacement cushion and place the cushion
around the hole and press. (Hygiene kit item
no. 99400/99401). Hygiene kit should be
exchanged at least two times per year.
- The fitting of hygiene covers to the
cushions may affect the acoustic
performance of the earmuffs.
- This product may be adversely affected
by certain chemical substances. Further
information should be sought from the
manufacturer.
(*1)Fitting and adjustment
Noise reduction will be adversely affected
by anything that impairs the seal of the
earmuff cushions against the head, such
as thick spectacle frames, balaclavas, etc.
Remove all hair under the cushion and fit
the ear cups over your ears so that they sit
comfortably and snugly. Ensure that your
ears are totally enclosed by the cups and
that you get an even pressure around your
ears.
(*1a)Headband
Adjust the protector to its largest size and
put it on. Now adjust the headband so that
the protector rests lightly on your head.
(*1b)Neckband
Adjust the protector to its largest size and
put it on. Now adjust the headband strap so
that the protector rests lightly on your head.
(*1c)Cap/Helmet mounted
Adjust the protector to its largest size and fit
the ear cups over your ears. Adjust the ear
cups so that the cap/helmet rests lightly on
your head.
Care
Clean with mild detergent (soap). You must
be sure that the detergent does not irritate
your skin. The hearing protector should be
kept in a dry and clean place, for example in
the original packing.
Warning
If the instructions are not observed
attenuation can dramatically decrease. The
earmuffs should be worn at all time in noisy
surroundings!
