Is there a way to unlock my panasonic scpt660 Five-DVD Home Theater System? please help.

The following is what "Panasonic" recommends:
While stopped and “DVD/CD” is the source, press and hold [∫] (Stop) on the main unit and [S10]
on the remote control until “INITIALIZED” disappears from the TV. Turn the unit off and on again.
All settings will return to the default values.
(This does not work during program and random modes, or when setup menu or START menu is
displayed.)

Scribd.com suggests the following: Open the dvd drawer, press 9,8,1,7 on the remote. Press enter until it shows region 9 then press RETURN.
Hope this helped!
