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.

To remove ice bin: 1. Pull the covering panel out from the bottom and slide it to the rear.
2. Lift the signal arm so it clicks into the OFF (up) position. Ice can still be dispensed, but no more can be made.
3. Lift the front of the storage bin and pull it out. 4. Empty the ice bin. Use hot or warm water to melt the ice if necessary. Never use anything sharp to break up ice in the bin. This can damage the bin and dispenser mechanism. 5. Wash with mild detergent. Rinse well. Do not use harsh or abrasive cleaners or solvents. 6. When replacing the bin, make sure it is pushed in all the way. Then push the signal arm down to the ON position to restart ice production.
