We provide a menu system that hides the standard desktop and provides easy access to commonly used features. It is called "System Menu" and is started by factory default. You can access the menu through either hardware keyboard or touch screen.
When you want to change to the default desktop screen, select the button [X] located at top right corner. And when you want to change this menu screen again, please press reset switch. And if you want to disable the System Menu after system start, go to "5.Options" -> "1.Delete System Menu". Once deleted, you will have to perform "User Disk Clear" operation ("full reset") to restore the device to factory default settings and have the System Menu started automatically again. After executing full reset, all data on your device will be lost!
