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

panel
The front panel is locked and the PANEL LOCK button is illuminated. Pressing a button
has no effect.
To unlock the VP-747:

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
