I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
The product was good and just what I needed, however I had moderate difficulty with the down load because the sight would not recognize my pass word. I was finally given a direct link to the manual and that worked.
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!
