Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Dirty filters will degrade the washing result. 0 1. Open the door, remove the lower rack. 2. The dishwasher filter system comprises a coarse/fine filter, microfilter and a flat filter. Unlock the filter system using the handle on the microfilter, and remove. 3. Turn the handle about ¼ a turn anticlockwise and remove. 4. Take hold of the coarse/fine filter (1) by the handle with the hole and remove from the microfilter (2) 5. Clean all filters thoroughly under running water. 6. Remove the flat filter (3) from the base of the washing compartment and clean both faces thoroughly
7. Put the flat filter back in the base of the washing compartment 8. Place the coarse/fine filter in the microfilter and press together. 9. Put the filter combination in place and lock by turning the handle clockwise to the stop. During this process ensure that the flat filter does not protrude above the base of the washing compartment.
