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 
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.
