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.

CARE AND MAINTENANCE
Cleaning the filters
1. Rotate the microfilter counter-clockwise (in the direction of the arrow �0�) and extract it (E). 2. Remove the wide-mesh filter (F). 3. Remove the fine-mesh filter (G). 4. Clean all filters under running water, paying attention not to bend the fine-mesh filter. Check that no impurities are left inside the dishwasher! 5. To reassemble: insert the wide-mesh filter into the microfilter so it clicks into place. Insert the fine-mesh filter. The filter must be fitted under both tabs (H). Insert the wide-mesh filter / microfilter unit and turn clockwise (in the direction of the arrow �1�), until the dashed lines on the microfilter and fine-mesh filter are aligned. The filter unit must be correctly assembled to ensure good wash results!
