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.
