A while back, I acquired one of these systems from a restaurant equipment auction. It is now fully functioning in my restaurant. Along the way, I was forced to decipher the above manual. Though I haven't made it very far in regard to the system programming, it is working quite well. It is reliable and always on. Hopefully you find some of this information helpful, as I agree with Cashel - 3 through 15 are a little tricky. Took me a while to get it sorted out. The following are hosted on my business server: https://www.home-skillet.com/_win36d/my36dguide.pdf and https://www.home-skillet.com/_win36d/win36dmanual.pdf . My guide is first, and the actual manual is second. This should alleviate some headache. Good luck!
