SAT question

[pryan2]

Terry,
When you enter  your FAC notes, you are tuning A4 while the machine is set
at (listening to) A5, so you are not tuning A4 at 440 at this point.  After
you have finished the FAC procedure, then you must re-tune A4 to A4, that's
when it should be right on 440.  In some cases the machine  is a little off
at this point  and you must enter an offset, but I find it's rare for this
to happen.  Good Luck.

was at A440

just don't get it.
