Headset - side tone / wake-up tone*
For headsets which have "side tone" implemented internally, it is recommended to
switch this function off here. Otherwise, you will hear your voice too loud or doubled
in the headset earphone.
When using headsets which go into an idle mode after a certain time, it is recom-
mended to switch on the wake-up tone. That way you avoid the caller’s first words
being lost.
Press the "Menu" function key.
Scroll to the Settings menu item.
Confirm your selection.
Scroll to the Applications menu item.
Confirm your selection.
Scroll to the Headset menu item.
Confirm your selection.
Scroll to the Side tone or Wake-up tone menu item. An indication on the right
hand side of the window shows whether the function is on or off.
Press this key to change the setting.
Exit menu. The new setting is saved.
