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.

Maintenance and Cleaning
Before any maintenance or cleaning work is carried out DISCONNECT the appliance from the ELECTRICITY supply. If the refrigerator only is to be cleaned, press the FROSTMATIC button several hours in advance, in order to build up sufficient chill reserve in the freezer compartment for the interruption in service. Do not open the freezer compartment door. 0 1. About 12 hours prior to defrosting push the FROSTMATIC button, in order to build up sufficient chill reserve for the interruption in operation. Caution! Do not touch frozen goods with wet hands. Hands can freeze to the goods. 2. Remove frozen goods, pack them in several layers of newspaper, cover them and store them in a cool place. 3. Defrost the freezer compartment (see section: "Defrosting"). 4. Switch off refrigerator and freezer and remove plug from the mains, or switch off or turn out the circuit breaker or the fuse. 5. Clean the inside and accessories with warm water and bicarbonate of soda (5 ml to 0.5 litre of water). Rinse and dry thoroughly.
Warning! Do not use detergents, abrasive powders, highly perfumed cleaning products, wax polishes or cleaning products containing bleach or alcohol. 6. Regularly check the door seals and wipe clean to ensure they are clean and free from debris. 7. Regularly unblock the condensation water drainage hole in the rear wall of the refrigeration chamber with the aid of a piece of wire. Accumulation of dust at the condenser increases energy consumption. For this reason carefully clean the condenser at the back of the appliance once a year with a soft brush or a vacuum cleaner.
