I've searched the archives of the Bernina 820/830 Yahoo Group trying to figure out how one goes about determining their machine's stitch count/hours of use. I'm planning to sell my 820, and thought it would help if I could offer that information to the potential buyers. It seems to be attainable information since other sellers of computerized Berninas list their stich count/hours of use....But I can't figure it out. I must admit, I am a little technologically challenged. Thanks in advance for your replies. :)
