Resetting
In the event that the MLC 52 needs to be reset, you can do so by one of the
following methods:
Factory firmware reset — Press and hold the bottom right button (the Video button
on standard models or the blank button on VC models) while applying power
to the MLC. This method resets the MLC firmware to the version with which
the unit was delivered from the factory. Any codes that you previously
programmed for the buttons remain in effect.
Factory configuration reset — Press and hold the On and Off (Display) buttons
simultaneously while applying power to the MLC. This method removes all
codes from the buttons.
You can also reset the MLC to its factory defaults via the Windows-based
configuration software. See “Resetting” in chapter 5, “Serial Communication.”
Locking the Front Panel (Executive Mode)
To prevent access by unauthorized users, or accidental presses of the button
issuing unwanted commands to devices, the front panel controls can be locked
using executive mode. When the MLC 52 is in executive mode, all front panel
functions are locked, so that pressing the buttons has no effect.
If a button is pressed while the MLC 52 is in executive mode, all the front panel
buttons blink, indicating that the front panel is locked.
To place the MLC in executive mode,
1. Power off the display device. Executive mode cannot be enabled if the device
is on.
2. On the standard MLC 52 models, press and hold the Vol
>
and Video buttons
simultaneously for 5 seconds.
On the VC models, press and hold the unlabeled button (bottom right) and
the VCR button simultaneously for 5 seconds.

then return to their original state.
