Correctly measuring FAC notes for AccuTuners.

[Jim Coleman, Sr.]

Hi Joe:

I wish I could say that FAC is simpler on the SAT III, but it is just 
the same except choosing the Page number is a little simpler since we
have independent page buttons now.

My forgetter is working better than my rememberer. In one of my recent
posts, I forgot to mention selecting the note F5 before measuring F3.
