One of the threads from another subject touched on the Walther's turntable and the fact that it could not be manually set. I spoke with Dennis from the parts department at Walther's today and he told me how to do it. Go to the program mode and press the go button. The program mode will begin flashing and at that point push the up or down button to rotate the bridge. Press the button again to stop the bridge where you want it then hit escape. It will stay in that manually selected location. Hope that helps the people from the other discussion.
