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.
Text excerpt from page 10 (click to view)
The appliance needs ventilation
Air is fed under the door through the vent slots in the base and is vented upwards along the back wall. To ensure proper air circulation never cover or alter the vent openings. Attention! If the appliance is installed under, for example, a hanging cabinet, a clearance of at least 10 cm between the top of the appliance and the cabinet above it must be maintained.
0 1. Break both wall spacing elements
from the plinth and insert them into the sockets at the back side of the appliance, according to the figure, so that the required wall gap for the necessary ventilation at the back of the appliance is provided for.
0 1. The appliance must have a solid, level footing. Please compensate for
unevenness in the floor by turning the two adjustable feet at the front in or out.
