EFE - "easy for everyone". After downloading to your 9400 press "start", lay back and enjoy all the macros. Use the home key to reach the main page of selected device, press the arrow key to get to the macros for this device. With the small direct keys on the top of most pages you jump to other devices without using the macro. Pressing the book key (looks like two opened pages) you'll reach the amp if you want to select a source manually. From the amp page you reach the home page with the 5th hardkey (house symbol). All the buttons will remind you a little bit of the iPhone. They are designed with PaintShopPro and optimized for best readability and nice optics in crystal style. Each Device has its typical colour for best clarity. Hope you like it, its made with German Gruendlichkeit ;-)
