Hi

It's very strange because on my PSR 740 the Mic In Jack
is on upper cover and the Phone Jack is at lower cover (as
in page 13 of owner's manual.
In the demonstration the two jacks are on the same surface,
like a unique triangle.
Also the messages about Vocal Harmonizer are different
or have a different layout than my 740 on which is equal to
page 84 of owner's manual.
