Setting the screen saver
Introduction
You can set the following time intervals on the HMI device:
● For the automatic activation of the screen saver
● For the automatic reduction in the screen's backlighting
If no input is made within the predefined time interval, the function is activated automatically.
The screen saver and the reduced screen backlighting functions are switched back off by
means of the following actions:
● By pressing any key
● By touching the touch screen
The function associated to the key or button will not be executed by this.
Note
Reduce backlighting
The brightness of the backlighting decreases incrementally during its operational life. In
order to increase the operational lifetime of the backligh
ting, activate the backlighting
Activating the screen saver
Generally, you should always activate the screen saver. Otherwise, the screen contents may
leave a burn
-in effect in the background if they appear too long.
This effect is reversible.
When the screen saver is active, the backlighting is reduced at the same time.
