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.

Bleeding part of the moisture of cooling chambers in form of frost and ice goes with the operation of the appliance. Thick frost and ice has an insulating effect, so it reduces cooling efficiency as the temperature increases in the cooling chambers, they need more energy. At this type of appliance defrosting the cooling surface of the refrigerator is automatic without any external intervention.The thermostatic control interrupts the operation of compressor at regular intervals for more or less time - during this cooling is interrupted - the temperature of the cooling surface goes above 0 Â°C due to interior heating load of the compartment, so defrosting occurs. When the surface temperature of the cooling surface has reached +3 - +4 Â°C the thermostatic control restarts operation of the system. Melting water flows through defrost water outlet leaded through the back into the evaporator tray maintained on the top of compressor and evaporates due to its warmth. Check and clean the outlet of melting water coming during defrosting regularly a label inside the appliance warns you for this. If it is clogged the melting water gathered can cause earlier failure as it can go to the insulating of the appliance. Clean the melting water outlet with the supplied pipe scraper that can be seen in the figure. The pipe scraper has to be stored in the outlet. The most typical case of clogging up in the melting water outlet when you put food wrapped in some paper into the appliance and this paper contacts back plate of the refrigerator and freezes to it. If you remove the food right at this moment the paper will tear and it can cause clogging up in the outlet by getting into it. So you are asked to be careful - because of the above - when placing foods wrapped in paper into the appliance. In case of increased demand e.g. during heatwaves, the refrigerator temporarily happens to operate constantly - during this the automatic defrosting does not work. Remaining small ice and frost stains on back plate of the refrigerator after defrosting period is not abnormal. The freezer can not be equipped with automatic defrosting set since the deep-frozen and frozen foods do not endure melting temperature. When small frost and ice occurs scrape off and remove frost and ice coating with the supplied plastic scraper. When ice coating is so thick that it cannot be removed with the plastic scraper, the cooling gill have to be defrosted. Frequency of defrosting depends on usage 9
