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.

Operating Instructions
Inserting the Shelf and Tray
The shelf has two guide rails on the right and left sides. These must always be facing downwards. Inserting the shelf Insert the shelf so that the two guide rails face downwards. Insert the shelf on the oven shelf runner rails so that the two holes engage in the retaining bolts of the oven shelf runner rails. Inserting the baking tray / universal tray Insert the trays so that the anti-tip device faces to the rear. Insert the trays on the oven shelf runner rails so that the two holes engage in the front retaining bolts of the oven shelf runner rails.
Inserting the shelf and tray When using the shelf and universal tray together, place the shelf exactly in the recesses of the tray.

To make it easier to position slide-in units if the rails have been pulled out differently, place the slide-in unit on the rails at the back, push it in as far as it will go and then lower it into the retaining bolts at the front.
