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.

Rengøring og vedligeholdelse af
Af hygiejniske og sikkerheds mæssige årsager skal pladerne holdes rene. Fedtpletter og spildt mad afgiver os ved opvarmning, og kan i værste tilfælde medføre brand.
Aftagning af panel
For at lette rengøring af panel og overplade kan De tage panelet af: Sådan gør De: 1. Tag fat i panlet som anvist på tegningen 2. Løft panlet lige op 3. Rengør overpladen som anvist under �rengøring af stålpladen� 4. Når overplade og panel er helt tør monteres panelet igen.
Brug aldrig hårde eller skarpe genstande til at løfte panelet af med Panelet må ikke rengøres i opvaskemasinen. Apparatet må ikke bruges uden panelet er monteret
