If you have not set your PIN-code when you first turned on the TV set, you need to do this before you can use the Child lock feature.

If you forget the PIN Code, unplug the AC power cord for 10 seconds to restore the PIN Code to 0000.

If you need to set your PIN Code for the first time, proceed as follows:

1. Press the ' MENU ' button on the remote control to access the main menu.
2. Press the cursor up/down to select FEATURES and press OK.
3. Press the cursor up/down to select Child Lock and press OK.
4. When the Enter PIN appears on the screen, enter '0000'.
