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.

HINTS AND TIPS
�
Arrange the shelves in the required positions before switching the oven ON. Shelf positions are counted from the bottom upwards.
�
When cooking more than one dish in the fan oven, place dishes centrally on different shelves rather than cluster several dishes on one shelf, this will allow the heat to circulate freely for the best cooking results.
�
When batch baking one type of food, e.g. Victoria sandwich cakes, those of similar size will be cooked in the same time.
�
It is recommended that when baking larger quantities the shelf positions should be evenly spaced to suit the load being cooked. A slight increase in cooking time may be necessary.
�
Do not place baking trays directly on the oven base as it interferes with the oven air circulation and can lead to base burning; use the lower shelf position.
Do not place cookware and cooking pots with rough bases e.g. cast iron on the oven door as damage to the glass may occur.
