1. To switch the microphone ON, move the microphone arm down far
enough to place the microphone in front of the corner of your mouth.
The microphone will switch ON as soon as the microphone arm
reaches a position lower than horizontal.
2. Talk into the microphone.
Refer to fig. 5:
The flexible microphone arm
allows you to adjust the micro-
phone sound by varying the work-
ing distance. As you move the
microphone away from your
mouth, the bass content (and
overall level) of the audio signal
will decrease.
3. To mute the microphone, move the microphone arm up into its
detented center position. The microphone will be muted as the
microphone arm reaches a position higher than horizontal.
The headphones on models HSC 271, HSD 271, and HSD 271 Single
will switch ON automatically as you put the headset on. When you take
the headset off, the headphones will switch OFF automatically. This
prevents the headphone signal from leaking into the microphone on
taking the headset off.
The on/off switch is actuated by the headband. If you hang the head-
set up by the headband, the headphones may switch ON.
The headphones on models HSC 171 and HSD 171 feature no auto-
matic on/off switch.
If you use the headset in the open or need to place the microphone
extremely close to your mouth, we recommend using the supplied foam
windscreen.
1. Slide the windscreen onto the microphone capsule.
2. Pull the windscreen over the outer edge of the microphone capsule.
