V-Chip Lock When turned on, blocks access to mature television and movie content, based on the MPAA and TV PG ratings selected below, unless the viewer enters a password (set below). Set Password Sets the V-Chip password. To change the password, enter the current password followed by the new password. The factory-default password is '1234'.
