 Pick up/hang up the handset.
 There is an incoming call.
 A new prompt (for example, missed call, new voice mail or forwarded call).
 The status of BLF key changes.
If your phone is idle again for a specified period of time, the screen saver will start again. The
time & date and certain feature status icons (for example, auto answer, DND, a new text
message) will also display on the screen saver. For more information on the icons, refer to Status
Indicators.
You can upload custom pictures to set up a screen saver of your picture, configure the screen

saver wait time and configure the phone whether to display custom XML items (for example,
notifications or company logo) on the screen saver or not. The custom XML items (for example,
notifications or company logo) are preset by your system administrator.
