error message on sanyo 235?

Hi. That's a rare machine now but very good model. I used to work on them but I don't have the info any more. You're going to need a manual probably. Only one I know of is at C-tech as they are Sanyo agents for the old models:

Copy and paste the above into your browser and it'll take you to their site. Sorry I can't be of more help. They are good guys. I bought three manuals and they gave free help since I bought the manual. Good luck
