Operation
Turning the microphone boom
The microphone boom can be rotated. This allows the
headset to be worn with the microphone boom positioned
on either the left or right-hand side of the head.

5
Putting on the headset
When putting on the headset, the patented two-piece
headband adjusts automatically.
Positioning the microphone
Bend the flexible microphone boom so that the micro-
phone is placed at the corner of the mouth. Maintain a
distance of approx. 2 cm between microphone and mouth.

6
Flipping away one earcup
The headset features a “flip-away” earcup for single-
sided listening.
Adjusting the volume directly on the audio system
Connect the headset to the corresponding sockets 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!

7
Adjusting the microphone sensitivity
The microphone sensitivity has been factory pre-set to
80 mV/Pa. You can change the microphone sensitivity by
turning a small screwdriver in the direction of the arrow.

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. Do not use any
solvents or cleansing agents.
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.
CAUTION!

Accessories and spare parts
By changing the cable, you can simply retrofit your
headset (see “Product variants” on page 11).
