Operation
Turning the microphone boom
The microphone boom can be rotated by 180°. This allows the
headset to be worn with the microphone boom positioned on
either the left or right-hand side of the head.
Switching the microphone transmission off
If, during turning, the microphone boom is in the middle position
(90°), the microphone transmission will be switched off in order
to prevent disturbing noise.

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 microphone is
placed at the corner of the mouth. Maintain a distance of
approx. 2 cm between microphone and mouth. Always use the
supplied wind and pop screen.

Do not position the microphone directly in front of your
mouth as it will pick up your breathing and plosive
noises from your mouth. In addition, moisture can
adversely affect the sound and performance of your
microphone.
When attaching the
sound inlet basket,
make sure that it locks
into place with an
audible click.
Make sure not to cover
the sound inlet.

Flipping away one earcup
The headset features a “flip-away” earcup for single-sided
listening.

7
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.
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!
Set the volume to a medium level. Make sure
that you can hear critical environmental sounds.
Switching ActiveGard™ on and off
ActiveGard™ safeguards your ears from volume peaks above
105 dB, which can be transmitted via the audio system or radio
equipment. ActiveGard™ is factory-preset to “on”. You can
switch ActiveGard™ off by gently sliding the switch to the upper
position using a pointed tool.
