Your welcome. It's not much of a manual in my opinion but I'm sure it's better than no manual. At least you will know all the codes. And now I will be able to ask you questions about it for things I never understood!
Ya, the manual is horrible all right ...... But it is the right manual and as you say, it lists the codes.
All I can say is that I'm sure glad I also have a TECO. I can at least compare them a bit to figure things out.
My laugh emoji is about you calling me for info now. Good luck with that! Two old blind guys trying to help each other make sense of something written on another planet.....
Edit - that sounds kind of ungrateful. That's not my intent. I am VERY grateful and appreciate your help VERY much. I can't imagine using that thing without your help.
