Operation
Putting on the headset
When putting on the headset, the patented two-piece
headband adjusts automatically.
Flipping away one ear cup
The headset features a “flip-away” ear cup for single-
sided listening.

5
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 2 cm between microphone and mouth.
Turning the microphone boom
The microphone boom can be rotated. This allows the
headset to be worn with the microphone boom posi-
tioned on either the left or right-hand side of the head.

6
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.
Adjusting the microphone sensitivity
The microphone sensitivity has been factory preset to
80 mV/Pa. You can change the microphone sensitivity by
turning a small screwdriver in the direction of the arrow.
CAUTION!
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!
왘Set the volume to a medium level. Make sure that
you can hear critical sounds such as warning alarms.
