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.

Oven cleaning cycle
You need to follow the cycle to keep the inside of the oven in good condition. The type of cooking you do will affect how often you need to follow the cycle. If you do a lot of roasting and very little other baking you should follow the cleaning cycle once a week. If you do very little roasting you will only need to follow the cleaning cycle every 2-3 weeks. To carry out a cleaning cycle: 1. Remove the oven shelves.
2. Set the oven to mark 5 for at least 30 minutes.
3. Turn the temperature up to mark 7 for 2 hours or until the oven is presentably clean.
Do not use any cleaning agents or scrapers on the inside of the oven. Do not wash the special finish.
General
Clean the base of the oven, the oven shelves and the oven door while they are still slightly warm. This way you can easily remove any splashes and spills. Wipe the base with a cloth that has been wrung out in hot soapy water. You may use mild abrasives.
