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.

Pressure Testing
1. Remove left hand pan support and front left burner cap and crown. 2. Fit manometer tube over the injector. 3. Turn on the burner gas supply and ignite another burner. 4. The pressure reading should be nominally 20mbar and must be between 17 mbar and 25mbar. 5. Turn off the burner supplies.
Conversion from Natural Gas to LPG
It is important to note that this model is designed for use with natural gas but can be converted for use with butane or propane gas providing the correct injectors are fitted. The gas rate is adjusted to suit.
Method
1. Ensure that the gas taps are in the 'OFF' position 2. Isolate the hob from the electrical supply 3. Remove all pan supports, burner caps, rings, crowns and control knobs. 4. With the aid of a 7mm box spanner the burner injectors can then be unscrewed and replaced by the appropriate LPG injectors (see "Characteristics of gas burners" on the back cover of this book).
To adjust the gas rate
With the aid of a thin bladed screwdriver completely tighten down the by pass adjustment screw. Upon completion affix the replacement rating plate on the under side of the hob.
IMPORTANT
The replacement/conversion of the gas hob should only be undertaken by a competent person.
