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.

CARE AND MAINTENANCE
Cleaning the filters
1. Rotate the microfilter counter-clockwise (in the direction of the arrow �0�) and extract it (E). 2. Remove the wide-mesh filter (F). 3. Remove the fine-mesh filter (G). 4. Clean all filters under running water, paying attention not to bend the fine-mesh filter. Check that no impurities are left inside the dishwasher! 5. To reassemble: insert the wide-mesh filter into the microfilter so it clicks into place. Insert the fine-mesh filter. The filter must be fitted under both tabs (H). Insert the wide-mesh filter / microfilter unit and turn clockwise (in the direction of the arrow �1�), until the dashed lines on the microfilter and fine-mesh filter are aligned. The filter unit must be correctly assembled to ensure good wash results!
