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.

Minimum level adjustment of gas oven burner
This procedure must be undertaken by a competent and qualified engineer only. 1. Disconnect the appliance from the mains supply. 2. Remove all the knobs. 3. Open the oven door and locate the ventilation grill which is fixed right below the control panel. 4. Remove the rubber caps from the ventilation grill then undo the two fixing screws (�A�) and finally take the grid off. Undo the two fixing screws (�B�) which keep the control panel in place, then take it off the appliance. With a thin bladed screwdriver, completely tighten the minimum level adjustment screw (�C�). Refit all the oven parts following the above described procedure backwards. Restore the mains supply. Do not restore the mains supply if all the removed parts have not been fitted back in their original position.
