Be sure to add me to your favorites list Original Yamaha PSR-540 Portatone Digital Keyboard Owner's Operation Manual. This is an original Yamaha User's / Owner's / Operating Manual for the advanced Yamaha PSR540 Portatone keyboard. It's in overall very good condition, and it's complete and very helpful if you have one of these excellent Portatone keyboards. This manual is all in English and has a thick 160 pages of great information on using, playing and caring for your awesome PSR. I have 2 of these available at this time, the one with the most wear (which isn't very much) is in the photos. 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!
