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.

The grill
The grill is a high-speed grill. The instructions below tell you how to vary the heat setting and how to change the height of the grid to suit the food you are cooking. You should remember to turn the food regularly. You should not use the grill to keep food warm as it will continue to cook the food.
Prior to using the grill
We suggest that you operate the grill for approximately 5 - 10 mins to burn off any residue from the surface. During this period a slight odour may be emitted, it is therefore advisable to open a window for ventilation. When you first operate the grill you may hear some sounds as the burner heats up, this is quite normal and is not a fault on the appliance.
For your safety
The grill pan and handle must be in place before igniting the grill. You must keep the grill door open when the grill burner is lit. Accessible parts may be hot when the grill is used. Young children should be kept away. Never cover the grill pan or grid with foil as this can lead to grill fires.
Heat control
The grill control has two heat settings. The control knob turns to the right from 'OFF' to 'LOW' and then to 'HIGH'. Use the high setting for fast cooking such as toast. Use the low setting to cook thicker food such as chicken after you have browned it on the high setting.
