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.

Freezer
The freezer compartment of this model is of the «frost -free» type. This means that no frosting occurs on the inner walls of the compartment or on food during operation. The absence of frosting is achieved by constant circulation of cold air inside the compartment, produced by an automatic fan blower. The water produced by defrosting flows away - in the case of the both the freezer and refrigerator compartments - through special drainage grooves into a container positioned at the back of the appliance above the compressor where it then evaporates. Important A temperature rise of the frozen food packs during defrosting may shorten their safe storage life. Never use sharp metal tools to scrape off frost from the evaporator as this could damage to the appliance beyond repair.
