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´s for your help, I already recived these manual from you

1.
Use only flat-bottomed utensils that make good contact with the surface units. To check the flatness of a utensil: l Turn it over and check the bottom of the pan by placing a ruler across it. l Rotate the ruler in all directions. There should be no gaps between the pan and the ruler. lid.
