Front Panel Security Lockout (Executive Mode)

To prevent accidental or unauthorized changes to settings, the PVS switcher has a front panel security lockout (executive mode) that limits users’ access to front panel controls. When the executive mode is active, all functions are locked, and a red lockout LED (next to the power LED) lights to indicate that executive mode is on. When a button is pressed (or an encoder turned) during lockout mode, the associated LED blinks three times at approximately 0.3 second intervals to indicate lockout.

To turn executive mode on or off via the front panel:

1. Press and hold input selection buttons 1 and 4 simultaneously for 4 seconds (see figure 3-8).

2. Release the buttons when the input selection #1 LED and the Lockout LED blink once. The switcher has enabled or disabled the executive mode.
