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.

Appliance Description
Interior Illumination
(not included with all models) The illumination switches on automatically when the appliance door is opened. By closing the appliance door it is automatically switched off.
3
If the appliance door remains open for more than 5 minutes, the interior illumination starts to blink and then switches off automatically in order to save energy. If directly after opening the door the interior illumination is not glowing although the appliance is in operation (recognisable through the green mains control indicator), the lamp is defective. Exchanging procedure is described in the chapter "Replace light bulb".
Freezer tray
A freezer tray is inserted at the very top of the freezer compartment at the back behind the freezer compartment flap.
3
Berries, for example, can be pre-frozen on the freezer tray. Advantage: The berries are not squeezed and maintain their natural form. The frozen berries can then be stored in compartments or drawers packaged in individual portions.
Ice Packs
(not included with all models) For some models two ice packs have been inserted into the freezer tray. Refer to the section "Prior to Initial Start-Up" concerning freezing of the ice packs.
3
In the event of power failure or a malfunction at the appliance, the ice packs extend the period of time after which unacceptable warming of frozen goods occurs by several hours. Ice packs may also be used, in passing, in cold storage bags.
