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.
