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.

Making preserves
Oven function: Pizza Setting � For preserving, use only commercially available preserve jars of the same size. � Jars with twist-off or bayonet type lids and metal tins are not suitable. � When making preserves, use the first shelf position from the bottom. � Use the shelf for making preserves. There is enough room on this for up to six 1-litre preserving jars. � The jars should all be filled to the same level and clamped shut. � Place the jars on the shelf in such a way that they are not touching each other. � Pour approx. 1/2 litre of water into the shelf, so that there is sufficient moisture in the oven. � As soon as the liquid in the first jars starts to simmer (after approx. 35-60 minutes for 1 litre jars), switch off the oven or adjust the temperature to 100°C (see table).
