Auto Adjust
The Auto Adjust function will be automatically executed
whenever the system is switched to a new mode. When the
system is changed to this mode again later on, the system will
not repeat the Auto Adjust function. This function is only valid
when the mode concerned is selected for the first time.

To unlock the Controls, proceed as follows:
1. Press the Power key to switch off the display
2. With one hand, press and hold the <-> and the <+> key at
the same time.
With the other hand, press the Power key shortly to switch
the display on again.
3. Keep holding the <+> and the <-> key for about 3 seconds.
4. At last, release the <+> and the <-> key.
Now, by pressing the Menu key, the OSD menu will appear.
