Be sure to add me to your favorites list Casio CT-647 and CT-648 Digital Piano Keyboard Owner's User's Operating Manual Booklet This is scanned and then printed paper hard copy reproduction version of the owner's / user's / operation manual for the CASIO CT647 electronic keyboard. It is also to be used with the CT648 model as well, as it is essentially the same keyboard, just with some cosmetic differences. This is all in English language, and extremely helpful with the operation, use and care of your Casio. This is one of Casio's excellent digital portable keyboards, and you need the manual to get the most out of it! This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thanks for looking! Check out my Store!
