Extron electronic MVX 128 manual Locking out the front panel Executive mode

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.

Performing a system reset from the front panel

The front panel reset is identical to the EZXXX} SIS command (see chapter 4, Programmer’s Guide). A system reset:

•Clears all ties and presets

•Clears all video and audio mutes

•Sets all input audio levels to unity gain (+0 dB)

•Sets all output volume levels to 100% (0 dB of attenuation)

Reset the switcher to the factory default settings by pressing and holding the RGBHV button and Audio button while you apply AC power to the switcher (figure 3-53).

NSystem reset does not replace user-installed firmware.

Press and hold the RGBHV and Audio buttons while you apply power to the switcher.
