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.

Filling with dishwasher salt
CAUTION! Use only special salt suitable for dishwashers
Unscrew the cap.
Only before filling with salt for the first time, fill the salt container with water
Using the funnel provided, pour in the salt until the container is filled with salt.
IMPORTANT! Water will overflow from the container as salt is added. IMPORTANT! Immediately start a complete programme.
Remove any trace of salt.
Replace the cap tightly turning it clockwise until it stops with a click.
IMPORTANT! The salt container will require topping up periodically.
The salt cap has a refill indicator window in the centre in which a green float is clearly visible when there is salt inside the container and almost disappears when the salt has finished.
