Putting the headset system into operation
Adjusting the audio signal/dial tone
Set the ABC switch to A (default setting), B or C so that you can hear a
clear dial tone in the headset.
Adjusting the microphone sensitivity
By default, the microphone volume control is set to between position 4 and position 5. This setting is suitable for most telephones and your voice gets reproduced at a good volume. To change the volume, adjust the microphone volume control accordingly.
The microphone volume control only adjusts the microphone sensitivity in Phone mode.
Make a call to someone who will help you find the correct sensitivity setting for your microphone (see page 25).
Turn the microphone volume control so that the other party can hear
at a comfortable level.
