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.

Caring for the filters
Grease filters
The Grease Fitters are located beneath the microwave oven. These filters should be removed and cleaned at least once a month. 1. To remove the filters: Place thumb in the indentation at the center front of the fitter. Push back and pull down. 2. To clean the filters: Soak in hot water and a mild detergent. Scrub with soft brush and swish to remove embedded dirt and grease. Rinse well and shake to dry. NOTE: Filters may be washed in the dishwasher, but aluminum will darken. Using ammonia for deaning will also cause the aluminum to darken. 3. To replace the fitters: Place the long edge of the filter against the clips at the back and push up until it snaps into place.
