In (Parental Controls), you must first set a password, called a "passcode". You must enter your passcode when you adjust the parental control settings or whenever you change them.
To set a passcode, select (Parental Controls) > [Start], and then follow the on-screen instructions.
If you forget your passcode, you must restore your system. Handle your passcode with care. Do not forget it and do not let third parties obtain it.
Select (Parental Controls) > [Start] > [Change Passcode], and then follow the on-screen instructions to change your passcode.
