Screen Saver
The screen saver will automatically start when the IP phone is idle for the preset waiting time. You can stop the
screen saver at any time by pressing any key or touching the screen. When your phone is idle again for a preset
waiting time, the screen saver starts again.
By default, the phone screen displays a built-in picture when the screen saver starts.
The following shows that the built-in screen saver is displaying on T46S phones:
You can set custom pictures as the screen saver. You can also add personal pictures on your phone using a USB
flash drive.
The time & date, certain status icons (for example, auto answer, DND, a new text message), or custom information
(for example, notifications or company logo) is also configurable to display on the screen saver.
The black-and-white screen IP phone only displays custom information as the screen saver.
