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.
