Alternatively, you can use the navigation keys to increase or decrease the volume. If these keys
have been programmed with functions different from the factory setting (Info, Profile), use a long
key-press to access the volume control. You can then adjust the volume by briefly pressing the
key as required.
SWITCHING THE RINGER ON/OFF
Switch off: Press the key and hold for a moment. The symbol appears on the display.
Switch on: Press the key again and hold for a moment. The symbol disappears.
SWITCHING THE RINGER OFF AT CALL
If you want to switch off the ringer for a call that has just come in, press the C key or the
softkey. You can still accept the call as long as the caller has not hung up.
ILLUMINATION /DISPLAY DIMMING
The keypad (722dt and 732d) and display are lit. Illumination is activated each time a key is
pressed or a call is made. The keypad and display remain lit for a user-definable amount of time.
To prevent the display illumination from switching itself off completely after that time, you can
activate display dimming. The display remains lit at a weak level for a maximum of 4 hours.
Activating this setting, however, reduces the battery life. You can make changes in the ••• ->
Settings -> Illumination -> Keyboard/Display/Display dimming menu.
ACTIVATING THE DISPLAY ILLUMINATION
If the display illumination is switched off completely, you can activate it using one of the three
keys below the display (softkeys) without triggering the function stored under that key.
CHANGING THE DISPLAY BRIGHTNESS / CONTRAST
Adjust the brightness of the display to your local conditions. Change the brightness in the ••• ->
Settings -> Display -> Brightness menu.
MUTING THE DECT PHONE
You can temporarily mute your DECT phone. Press the softkey. The symbol appears on
the display.
The other party in your phone call can no longer hear you.
Press the softkey again to unmute the DECT phone. The other party in your phone call can
hear you again.
Note: To save the new setting (i.e., to store it as a menu entry) press the Ok softkey
when making the adjustment.
