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.

Sostituzione del cavo di alimentazione
Nel caso di sostituzione del cavo è necessario usare solo cavi del tipo H05V2V2-F T90 adatti al carico e alla temperatura di esercizio. Inoltre, è necessario che il cavetto di terra giallo/verde sia più lungo di circa 2 cm. dei cavetti di fase e neutro (Fig. 11)- (Fig. 12). Dopo l�allacciamento provare gli elementi riscaldanti facendoli funzionare per circa 3 minuti.
