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.
For the SIP-T48S/T48G/T46S/T46G IP phone, you can upload custom pictures to set up a screen
saver of your picture, configure the screen saver type and screen saver display clock. For all IP

not. The custom XML items are preset by your system administrator.
