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.

Maintenance and Cleaning
Before any maintenance or cleaning work is carried out DISCONNECT the appliance from the ELECTRICITY supply.

Removing the ventilation grille
The ventilation grille can be removed, e.g. to wash the grille. Make sure the door is open when removing the ventilation grille. Unsnap the upper edge of the grille by pulling outward/downward. Then pull the grille straight out to completely remove it.
Internal Cleaning
Clean the inside and the accessories with warm water and bicarbonate of soda (5 ml to 0,5 litre of water). Rinse and dry thoroughly. Do not use detergents, abrasive powders, high perfumed cleaning products, wax polishes or cleaning products containing bleach or alcohol . Regulary check the door seals and wipe clean to ensure they are clean and free from debris.
External Cleaning
Wash the outer cabinet with warm soapy water. Remove the ventilation grille (see the section "Removing the ventilation grille") and vacuum-clean under the cabinet. Once or twice a year dust the condenser (black grille) and the compressor at the back of the appliance, with a brush or vacuum cleaner, as an accumulation of dust will affect the performance of the appliance and cause excessive electricity consumption. When moving the cabinet, lift it by the front edge to avoid scratching the floor.
To Change the Light Bulb
The light is switched on automatically when the door is opened. Before replacing the light bulb, disconnect the power plug from the outlet. To replace the lamp in the chiller compartment (only cabinets with two doors), first unscrew the lamp grille with a screwdriver. Use a bulb of the same type, E14 socket, maximum rating of 25 W.
