Locking the Front Panel
To prevent front panel input buttons being pressed accidentally
or by unauthorized users, you can place the switcher in
executive mode.
To toggle executive mode on and off, press the Input 1 button
and the Input 4 button simultaneously, and hold them down for
3 seconds. All front panel LEDs flash three times, indicating the
mode switch.
If an input button is pressed while the switcher is in executive
mode, all front panel LEDs flash once, then the switcher reverts
to the currently selected input.
N RS-232 communication remains enabled while the switcher
is in executive mode.
Resetting
If the switcher needs to be reset to factory defaults, press the
Input 1 button and hold it while applying power. All front
panel LEDs blink once to indicate that the switcher has been
reset.
N When the switcher is reset, the current build of firmware
is used instead of the version that was loaded at the time of
manufacture.
