You need to plug the device in to your computer with a USB cable. Then open Adobe Digital Editions on the computer and the program will take a second to link with your device. Then you should be able to see your device on the left hand side of the screen. Drag the book from ADE to where you see your device listed and it will transfer the book. Then close ADE and eject your device from the computer before you unplug it. Hope that helps.
