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.
Toggle the front panel lockout on and off by pressing and holding the Enter and
Preset buttons for approximately 2 seconds (figure 3-40).
