Adjust the length of the microphone boom so that the microphone is placed at the corner of
the mouth. To do so, loosen the quick-fixing device and adjust the microphone boom in length.
Pull the middle part of the microphone boom towards the mouth so that the distance between

Tilt the microphone for final positioning.
