sided listening.
Adjusting the volume directly on the audio system
Connect the headset to the correspondingsockets of your
audio system. Adjust the volume directly on the audio
system.
Hearing damage due to high volumes!
This headset is capable of producing high
sound pressure levels. Higher volumes or
longer durations can damage your hearing!
Set the volume to a medium level. Make sure
that you can hear critical sounds such as
warning alarms.
CAUTION!

Care and maintenance
Cleaning the headset
Use a soft, slightly damp cloth to clean the headset from
time to time. If the headset is very dirty, use a cloth
dampened with mild, soapy water.
Replacing the earpads
For reasons of hygiene, the black earpads should be
replaced from time to time. Grasp the edge of the foam
earpad behind the earcup as shown and peel it up and
away from the earcup. Slide the new earpad onto the
earcup. Repeat for the other earcup.
Danger of short-circuit due to the ingress of
water!
Water entering the housing of the headset
can cause a short-circuit and damage the
electronics.
Use only a slightly damp cloth to clean the
headset. Do not use any solvents or cleansing
agents.
CAUTION!

Manufacturer Declarations
Warranty regulations
The guarantee period for this Sennheiser product is 24 months from the
date of purchase. Excluded are accessory items, rechargeable or
disposable batteries that are delivered with the product; due to their
characteristics these products have a shorter service life that is
principally dependent on the individual frequency of use.
The guarantee period starts from the date of original purchase. For this
reason, we recommend that the sales receipt be retained as proof of
purchase. Without this proof (which is checked by the responsible
Sennheiser service partner) you will not be reimbursed for any repairs
that are carried out.
Depending on our choice, guarantee service comprises, free of charge,
the removal of material and manufacturing defects through repair or
replacement of either individual parts or the entire device.
Inappropriate usage (e.g. operating faults, mechanical damages,
incorrect operating voltage), wear and tear, force majeure and defects
which were known at the time of purchase are excluded from guarantee
claims. The guarantee is void if the product is manipulated by non-
authorised persons or repair stations.
In the case of a claim under the terms of this guarantee, sendthe device,
including accessories and sales receipt, to the responsible service
partner. To minimise the risk of transport damage, we recommend that
the original packaging is used. Your legal rights against the seller,
resulting from the contract of sale, are not affected by this guarantee.
The guarantee can be claimed in all countries outside the U.S. provided
that no national law limits our terms of guarantee.
