8.2 Ex-TRA Neckband Headset

8.2.1 Wearing method and microphone adjustment

Put on the headset, brush your hair away from your ear. Then adjust the
neckband so that it rests comfortably against your head. The neckband head-
set is equipped with an NC microphone. This suppresses unwanted ambient
noise and ensures speech is transmitted clearly. A precise adjustment of the
microphone is required in order to achieve optimum noise suppression. The
microphone capsule at the outer end of the goose neck arm should be located
approx. 1 cm from the corner of your mouth.
