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.

SG 320
The grill pan is supplied with a removable handle. To insert the handle, press the button on the handle with the thumb and pivot the handle slightly upwards inserting the lip into the widest part of the bracket. Move the handle towards the left, lower into position and release the button. Ensure the handle is positively located. When removing the handle, press the button on the handle with the thumb and pivot the handle slightly upwards and towards the right to remove from the bracket.
Ensure your hand is protected when removing the grill pan handle as the grill element can become very hot. ALWAYS REMOVE THE GRILL PAN HANDLE DURING COOKING. To correctly locate the grill pan on the shelf, ensure that the cut out on the underside of the handle bracket locates over the front bar of the shelf.
To check the progress of the food being grilled, the grill pan should be withdrawn on the shelf to attend to food during cooking.
