warning alarms etc.) may sound different to you. Before operating the aircraft, please make sure
that you can hear and recognise these sounds. Set the volume to safe levels that do not interfere
with your ability to hear important sounds and warning alarms.

How to prepare the Headset for Use
3.2.1 Adjusting the Headband
For best comfort and noise attenuation, the headband has to be adjusted to fit your head
properly.
Wear the headset so that the headband runs over the top of your head and adjust the headband
so that
• your ears are completely enclosed by the ear cushions,
• you feel a gentle pressure around your ears,
• both ends of the headband have the same length to ensure a proper fit
3.2.2 Adjusting the Microphone
• Place the wind shield onto the microphone and make sure that the microphone is completely
enclosed.
• Bend the flexible gooseneck so that the microphone is placed as close as in front of the
middle of your mouth. In order to avoid overstretching and premature wear and tear never
bend the gooseneck more than 90°.

to position the microphone on the left or right
hand side of the mouth.

potentiometer by using the supplied small
screwdriver (refer to the illustration).
