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.

Adjusting
(on some
the crisper
cover
track
models)
For some models: For your convenience, one crisper may be larger than the other, and your crisper cover may have an adjustable track so you can switch positions of the crispers. This allows you to store celery and other longer items in a crisper. You can adjust the cover track with the cover in the refrigerator by removing the crispers and the cover insert. To remove the crisper cover track: 1. Push up glass insert from bottom, then slide out with both hands. 2. Gently pull up on front end of track. 3. Pull rear end of track out of opening in cover.
To replace the crisper cover track: 1. Insert rear end of track (with hole) into opening in cover. 2. Lower front end of track into slot. 3. Make sure rear end of track snaps into place on underside of cover.
