Input Select: The large buttons in the Input Select section, labeled INPUT 1, INPUT 2, INPUT 3 and
INPUT 4 are used to select the desired input. After turning on the IN1403, press and release the
desired Input Select button. A green LED will light underneath the button to indicate the selected
input. The stereo audio signal associated with the input will automatically be selected at the same
time. All audio, video, and input settings for each input are stored internally (in memory) so the
adjustment(s) will not have to be repeated after they are optimized. To switch to another input,
simply press and release another numbered Input Select button.
When powered up, the scaler automatically returns to the last configuration, including the last
input selected.
Blank: The BLANK button can be used at any time to show a blank screen on the display device.
When blank is engaged, the output setting goes to black but the sync signals continue, ensuring that
the data display device retains sync lock. Simply press and release the button to engage blanking (the
green LED underneath the button will illuminate), and press and release it again to disengage. The
BLANK button has no effect on input 4, which is a passive input.
