The picture settings are adjustable by the 3 push-buttons of the daughjter PCB’s menu 
keypad. Press the 1. button to open the OSD settings menu or to switch to the next menu 
item. By pressing the other both push buttons the selected value will be changed. To avoid 
accidental changes during or after the installation, we recommend to disconnect the keypad 
from the pushbutton cable after the adjustments are done. Adjustments have to be done, 
while the selected input is visible on the monitor. 
 
Note: The OSD menu is only shown when a working video source is connected to the 
selected video-input of the interface.  
 
The following settings are available: 
 
Contrast 
Brightness
