Front panel security lockout (Executive mode)

The MVX Series switchers have a front panel security lockout feature (Executive mode) that limits the operation of the switcher from the front panel and optional IR remote control. When the switcher is locked, the Enter button, I/O button (video, audio, or video and audio selection), and all of the front panel audio gain and attenuation functions are disabled. The front panel input and output buttons continue to allow ties to be viewed, but ties cannot be created.

The front panel security lockout also disables the IR remote sensor to lock out remote control functions.
