On-screen keyboard keys or notes remain on the
display. A Step Up Lesson is in progress and the Digital Keyboard is waiting
for you to play the next note in the song. To stop this from happening,
cancel the lesson (page EN-33).
Screen contents are visible only from straight ahead. This is dues to production limitations. It does not indicate malfunction.
