Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

Cleaning
the interior
Hard water minerals may cause a white film to build up on the inside surfaces, especially just beneath the door area. To clean interior: l Apply powdered dishwasher detergent to a damp sponge to make a paste. OR l Use liquid automatic dishwasher detergent and clean with damp sponge. Wear rubber gloves. Do not use any type of cleanser other than dishwasher detergent because it can cause foaming or sudsing. NOTE: Follow the �Removing spots and film� procedure on page 24 to clean your dishwasher with white vinegar. Remember, this procedure is intended for occasional use only. Vinegar is an acid. Excessive use can damage your dishwasher.
Overfill
Protector
The Overfill Protector (in the front right corner of the dishwasher tub) keeps the dishwasher from overfilling. It must be in place for the dishwasher to operate. Check under the float for objects that may keep the protector from moving up or down.
