Adjusting Volume During a Call
During a call you have 8 levels to adjust the volume of the receiver/headset or the
loudspeaker. The setting is shown on the display.
To change the receiver or headset volume, press the
F arrow keys; to change the
loudspeaker volume, switch the loudspeaker on first and then press the
F arrow
keys.
Set volume via the
F arrow keys or the number keys. Pressing the F arrow keys
once raises or lowers the volume by one level.
Note
When the device is idle once again, it reverts to the default setting. You can
change this information in the “Phone settings” menu (see page 80).
Setting Volume for Incoming Calls
When you receive a call (and have not accepted it yet), you can temporarily change
the ringer volume. Use the
F arrow keys to do so. After you accept and end the
call, it reverts to the default setting (see page 80).
Switching off Ringer
If you wish to be sure you are not disturbed (e.g. during a meeting) you can switch
off the ringer. Incoming calls are then signalled noiselessly via the built-in
vibration signal generator (if activated) instead of the ringer. When the acoustical
ringer is activated, the symbol appears on the display.
Switching off Ringer
* When idle, press the star key – long key press
Switching on ringer
* When idle, press the star key – long key press
Alternatively you can switch the ringer on/off via the “Phone settings > Ringer
Settings > Device > Buzzer” menu (see page 79).
