"Screensaver" dialog
The screen saver is automatically activated if the HMI device is not operated within the
defined period of time.
On entering the value 0, the screensaver is deactivated.
Note
When the screensaver is activated, the back-lighting is automatically dimmed.
The screen saver is deactivated on pressing any key or touching the touchscreen. The
function assigned to that key/button is not triggered.
Dim back-lighting
For technical reasons, the brightness of the screen back-lighting is reduced with increased
operational use.. To increase the service life of the back-lighting, use the "Screensaver"
option in the Windows CE Control Panel to set the period of time after which the back-
lighting should be dimmed.
The back-lighting is automatically reduced if the HMI device is not operated within the
defined period of time.
On entering the value 0, dimming of the back-lighting is deactivated.
