Selecting Preferences
Temporary release of the Parental lock
When the parental level is set strictly, some discs may not be played back at all.
When you insert such a disc and try to play it, the XV-1000BK will ask you whether
you want the parental lock to be released temporarily or not.
If you select "YES", then enter your password, the disc will start playback.
If you enter a wrong password, the following message appears.
"WRONG! RETRY......."
If you select "NO", the parental lock on-screen display disappears.
