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

Building In
It is important that the dimension and materials of the surround or cabinet into which the oven will be built are correct and that proper arrangements are made for a continuous supply of air to the oven so it does not overheat. NOTE: The outer cabinet should have a 600mm width. Dimensions of the oven and recess required are given in the relevant diagrams.
