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.
Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

Interior Accessories
Storage Shelves/Storage Racks
Depending on the model, your appliance is equipped with either glass storage shelves or storage racks. A glass storage shelf must always remain inserted into the lower guide track above the fruit and vegetable trays, so that fruits and vegetable remain fresh longer. The remaining storage shelves can be adjusted to various heights: Pull the storage shelf forward and remove. Insert at a different height.
