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.

You can remove the panel in the oven bottom for cleaning.
Toremove:
1. Let oven cool.
2. Remove the oven racks. 3. Remove the two hold-down screws at the rear of the oven. If the screws are too tight to remove by hand, use a screwdriver.
4. Place your fingers in the slots in the bottom panel and lift the rear of the panel up and back until the lip at the front of the panel is clear of the front frame of the oven cavity. 5. Lift the bottom up and out.
