Be sure to add me to your favorites list ORIGINAL CASIO MT-500 KEYBOARD OPERATION / OWNERS MANUAL This is an original owner's / operation manual for the Casio / Casiotone MT500 mid-sized electronic keyboard. It is in good condition, and is complete and very helpful. It has both English and Spanish sections. Tones, auto accompaniment, use of optional drum pads, effects, specifications and more are covered. This booklet has a cover that's a bit yellowed with age, and there is a slight remnant of a stain on the back cover. This manual will be very useful for the MT-500 player and great for the Casio keyboard collector too! 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. Thank you so much for looking!
