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 hinged grill
This model has been fitted with a hinged grill element to enable you to clean the roof of the oven easily. Before proceeding ensure the oven is cool and is isolated from the electricity supply.
1) Undo the screw which holds the grill in
place (see diagram).

2) Then gently pull the grill downward to allow access to the oven roof (see diagram).
3) Clean the oven roof with a suitable cleaner and wipe dry before replacing the hinged grill element. 4) Gently push up the grill element into place and firmly screw into place the holding nut. Ensure the grill holding nut is firmly in place to avoid the grill falling down when in use
