Click on the Settings icon in the bottom left of the home screen
Touch the Advanced Settings icon in the top right corner and enter in your 4-digit master code
Choose the Power Down menu option and press OK
Once the screen completely turns off you may then disconnect the AC adapter from the power outlet.
