Front panel security lockout (Executive mode)
To prevent unauthorized changes, Executive mode locks all functions except input
selection functions and Program Audio Volume control. To toggle the Executive
mode on or off, press and hold the Mode button for more than 2 seconds until the
front panel LEDs change to View mode, then press and release the fourth input
button of the VGA/Audio group. The Exec Mode LED turns on to indicate that
Executive mode is on, and it turns off to indicate Executive mode is off. Release the
Mode button when your selection has been made.
Program audio
Single Switcher mode
In Single Switcher mode, audio from the one selected input is routed to the
program audio output.
In Separate Switcher mode, the selected audio input from one of the three input
groups is routed to the program audio output. The selected input and group is
indicated by a flashing input LED. The LEDs of the two remaining, unselected
groups (inputs) are steadily lit.
To route a different audio input within the same input group to the program audio
output, press one of the other input buttons within that group. The flashing LED
moves to the new input. See the illustrations below.
To route an audio input from a different group to the program audio, press the
input button once if the input is already active and its LED is steadily on, or twice if
the input is not active and its LED is off. The flashing LED moves to the new input
within the new group. See the illustrations below.
