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

Interior Accessories
Storage Shelves/Storage Racks
Depending on the model, your appliance is equipped with either glass storage shelves or storage racks. The glass shelf above the fruit and vegetable compartment must always remain in this position so that fruit and vegetables stay fresh longer. The height of the storage shelves can be adjusted: 0 To do this pull the storage shelf forward until it can be swivelled upwards or downwards and removed. 0 Please do the same in reverse to insert the shelf at a different height. Storing tall items: 0 Slide the half size glass storage shelf in the upper or middle level to the rear. By this means you will gain space to place tall items on the storage shelf below.
Variable door interior
Depending on your requirements, the storage compartments on the door can be removed and repositioned in a different place.
