Operation, cont’d

Locking out the front panel (Executive mode)

The front panel lock (Executive mode) limits the operation of the matrix switcher from the front panel. When the switcher is locked, all of the front panel functions are disabled except for the View-Onlymode functions. See Viewing a configuration on page 3-15. Other than in View-Onlymode, if the user pushes a front panel output button when the switcher is locked, the RGBHV and Audio LEDs flash twice and return to their previous state.

To toggle the front panel lock on or off, press and hold the RGBHV button and the Audio button for approximately two seconds (figure 3-52).

Press and hold the RGBHV and Audio buttons simultaneously to toggle the front panel lock on or off.
