This article outlines the recommended power settings for Clear Touch Interactive Integrated PC Modules. These settings will prevent unwanted shutdowns due to the display's built in power saving functions, as well as allow the display to properly power down when necessary (either through scheduled shutdowns in the Android "Startup and Shutdown Options" menu, or by holding down the panel's power button for several seconds.)
Under 'Shutdown Settings', you will want to make sure that all check boxes are UNCHECKED, please do not check any of the boxes.
This will allow you to be able to press and hold the power button on the front of the panel until a message appears to close and shutdown. Select OK (or wait for the 10 second countdown) and the panel will begin to shut down windows as well as power itself off. The power light will flash, but once it is a steady red, the PC and panel should be powered off.
