26 VP-747 - Understanding the VP-747
7.5 Locking and Unlocking the Front Panel
To prevent changing the settings accidentally or tampering with the unit via the
front panel buttons, lock your VP-747. Unlocking releases the protection
mechanism. When the front panel is locked, control is still available via RS-232,
the Ethernet, and/or the CONTROL connector.
To lock the VP-747:
• Press and hold for a few seconds the PANEL LOCK button on the front
panel
The front panel is locked and the PANEL LOCK button is illuminated. Pressing a button
has no effect.
To unlock the VP-747:
• Press and hold for a few seconds the illuminated PANEL LOCK button on
the front panel
Or the Lock key on the infrared remote control transmitter (see Figure 20)
• The front panel unlocks and the PANEL LOCK button is no longer
illuminated
For a description of the Save Lock and Input Lock OSD functions, see
Section 8.1.5.
