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.
The manual was properly scanned and perfectly readable. The only small problem is that I couldn't use my dear Ctrl + F to find a word I needed.

Cleaning the drain pump
Paper clips, nails and so on can sometimes get into the washing machine with the washing and remain in the drain pump casing. Fluff and strands of fabric can gather on these items and block the drain pump. Therefore the drain pump should be cleaned at least once a year. Warning! Switch off the washing machine and pull out the mains plug before cleaning the drain pump. 0 1. First carry out emergency emptying (see section "Carrying out emergency emptying�). 2. Place a towel on the floor in front of the cover of the drain pump. Surplus water may flow out. 3. Unscrew the drain pump cover anticlockwise and pull it out.
