Keyboard Changed Octaves - Need to change back

[Theophilus]

After about 14 years sitting in my garage, I finally pulled out and dusted off my old EX5, plugged it in and turned it on and it fired up nicely. HOWEVER, I put my music notebook on top of it and opened it up. The cover hit a bunch of buttons and now middle C is two octaves lower and I cannot figure out how to change it back. Can anyone give me some directions? I am perusing the manual but its been so long much of the terminology isn't syncing.

You have two octave shift buttons by the mod wheels. Try selecting those to shift it back.

There is also a global transpose setting in the utility mode that is worth checking.
