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.

DEFROSTING
The refrigerator automatically defrosts every time the compressor stops. The water is discharged, via the pipe, into a tray located beneath the appliance adjacent to the compressor, where it evaporates. Important To avoid defrost water overflowing and dripping onto the food in the fridge, periodically clean the water discharge hole (F) situated under the salad bins. Use the special cleaner provided (P) which you will find already inserted into the discharge hole The freezer compartment, however, will become progressively covered with frost. This should be removed with the special plastic scraper provided, whenever the thickness of the frost exceeds 4 mm. During this operation it is not necessary to switch off the power supply or to remove the foodstuffs. Never use sharp metal tools to scrape off frost from the evaporator as you could damage it. Do not use a mechanical device or any artificial means to speed up the thawing process other than those recommended by the manufacturer. However, when the ice becomes very thick on the inner liner, complete defrosting should be carried out as follows: 1. pull out the plug from the wall socket or turn the thermostat knob to the «O» setting; 2. remove any stored food, wrap it in several layers of newspaper and put it in a cool place; 3. leave the door open, place a basin on the top shelf of the refrigerator compartment, under the drain hole, remove the plug as shown in the figure; 4. when defrosting is completed, dry the interior thoroughly and refit the plug. Keep the scraper for future use; turn the thermostat knob back to the required setting or replace the plug in the power socket. After two or three hours, reload the previously removed food into the compartment. Important A temperature rise of the frozen food packs, during defrosting, may shorten their safe storage life.
