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.

How to Check and Clear Hose Blockages
Low suction or poor pickup may be due to a blockage in the vacuum cleaner. 1. Remove hose and check suction at end of hose - if little or no suction, check disposable dust bag. Change if needed. If no improvement proceed to step 2. NOTE: Turn off the switch and unplug the electrical cord before clearing hose. 2. Disconnect the hose adapter from the unit. Press adapter button on hose adapter and lift up. Check for any obstructions that may be in the hose. Any obstructions can be removed by using a blunt instrument to clear the hose. Flexing the hose may help loosen the clog. 3. Reinstall the hose after clearing the clog. Insert the hose adapter button into the bag compartment tube hole. Lift up on the hose adapter to be sure it is secured. NOTE: If no improvement in performance on carpet, proceed to following page. 1. Remove hose and check suction at end of hose.
