Hello everyone. Recently I got myself Dimter Opticut 104 crosscutting saw, from the year 1996. It is with full computer not with operating panel. It basically works fine and I do have a manual but it is in German which is very difficult to translate or to understand the translation. My question is: does anybody know how to delet error messages when I have fixed the error? Right now everytime I have to do restart to the computer to fix the error. I think manual says you have to press ctrl+F1, but it doesn't work.
