DBP-10 Protractor Instructions......

First, just read the instructions, from start to finish, including the examples.

Then, just take it one step at a time.
It is not a very intuitive system, but it does work, and work very well. I've used it for several years, (including half a dozen alignments), and have gotten excellent results with it every time.

Good Luck!
