4.2.1. Using the Dot Matrix Display - Model 7707VAT and 7707VAT-U
Additional signal and status monitoring is provided via the 4-digit dot-matrix display located on the card
edge. The card edge toggle switch is used to select which data is being displayed in the alphanumeric
display. Each time the toggle switch is pressed up/down, the display advances to the next/previous
display. A message indicating what display mode is active is shown for one second. After one second
without the toggle switch being pressed, the selected display data is shown. The card edge pushbutton is
used to select sub-items where applicable.
