Locking out the front panel (

mode)
The front panel security lockout limits the operation of the switcher from the front
panel. When the switcher is locked, all of the front panel functions are disabled
except for the View-Only mode functions. See Viewing a configuration on page 3-17.
Other than in View-Only mode, if the user pushes a front panel button when the
switcher is locked, the RGBHV (CrossPoint 450 Plus) or Video (MAV Plus) and
Audio buttons flash twice and return to their previous state.
To toggle the lock on and off, press and hold the RGBHV (CrossPoint 450 Plus) or
Video (MAV Plus) button and the Audio button for approximately two seconds
(figure 3-74).
