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.

Power Management
If a high heat setting (8 or 9) is set for the front left, rear right and front right cooking zones simultaneously, the hob control automatically brings about the optimal distribution of heating power. In this case the last cooking zone to be switched on takes priority and is allocated the selected heat setting 8 or 9. The automatic power management sets the remaining two cooking zones to heat setting 7. The heat setting displays for these two cooking zones display alternately the setting originally set (� / �) and �. The automatic warm up is not available for the front left, rear right and front right cooking zones if these three cooking zones are operated simultaneously. This means that if two of the rings are working in automatic warm up mode and the third ring is then also switched on, the automatic warm up will switch off automatically and the rings will be set to the selected heat setting. The a display shown in the display window changes to the set heat setting.
