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 commands that you previously programmed for the buttons remain in effect.

Factory configuration reset — Press and hold the On and Off buttons simultaneously while applying power to the MLC. This method removes all commands from the buttons.

You can also reset the MLC to its factory defaults via the MLC 52 configuration software (see the MLC 52/DVCM 50 Configuration Program help file for more information).

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.
