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 you for your manual It has the basic things to and i use the Oszi for Longer Time.

Adjusting
the crisper
humidity
control
You can control the amount of humidity in the moisture-sealed crispers. Adjust the control to any setting between LOW and HIGH. l LOW (open) lets moist air out of the crisper for best storage of fruits and vegetables with skins. l HIGH (dosed) keeps moist air in the crisper for best storage of fresh, leafy vegetables.
Adjusting
the crisper
cover
track
Because your crispers are not the same size, your crisper cover has an adjustable center track so you can switch positions of the crispers. You can adjust the center track with the cover in the refrigerator by removing the crispers and the cover insert. To remove the center track: 1. Push up the cover insert from the 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 center 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 has snapped into place on under side of cover.
