Using the LCD Screen
The scan converter's LCD screen informs you of status changes, allows you to configure the scan
converter, and provides access to menus that allow you to adjust the image. The screen normally
cycles through two default screens continuously. The first displays the scan converter model, and the
second displays the output frequencies. If the video scan rate is out of range, the default cycle screens
change to "Signal Out of Range" followed by the output frequency screen.
The Menu button allows you to exit the default screens and advance from one menu to the next. The
Next button allows you to step through the adjustment/selection screens within a menu. The front
panel cursor buttons (Up, Down, Left, and Right) can be used from the menu screens to make
adjustments and set parameters. The menu sequence is:
