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.

How to Check and Clear Blockages in Base
1. Remove the attachment hose from the lower hose retainer and look into the hose retainer for any obstructions. Proceed to Step 2 to check for any other blockages.
2. Remove the hood by loosening the two screws located on the top of the hood and lifting upward.
3. Step on the handle release and lower the handle all the way to the floor.
4. Check for blockages in the brush roll area and remove any obstructions found there. The base hose can be cleared of any blockage by using a blunt instrument.
5. After the blockage is removed, replace the hood and tighten the two hood screws (see Figure 2). Raise the handle to the upright position (see Figure 3) and replace the hose into the lower hose retainer.
NOTE: Blockages are not covered by the guarantee and any service calls to clear a blockage will be chargeable.
