Accessing Service Screens

To access the Service menu, tap each corner of the merchandiser portion of the screen in a counter- clockwise direction, starting in the upper right corner, to form a “C.”

Note: The screen will momentarily flash white when it is tapped in the correct spot.

Wait for the video display to come back, and continue to the next corner. If instead of white, a black square appears momentarily, it indicates that the software is an outdated version and requires updating.
