Voice Mail
If you have a new voice mail message waiting, a blue envelope icon
appears in the display. The

Backlight
To save power the backlight can be set to automatically either dim or turn off. This will happen after
the handset has been idle for a configurable time delay.
The display backlight automatically turns on again when e.g. an incoming call or message arrives, or
if a key is pressed.
The backlight turns off when handset is idle after a preset period of time delay.
The time delay can be adjusted between eight levels. The highest level will result in infinite time
delay, and the backlight will never dim or turn off. If the backlight is set to dim, and the lowest time
delay level is chosen, the backlight will always stay dimmed.
Note:
Turning display backlight off when handset is idle will save battery power.
