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.

Most second oven cooking should be carried out using the shelf provided in shelf position 2. However when cooking a small joint or a deep cake you can use the shelf on the base of the second oven to allow enough air to circulate around the food. Shelf on base For safety the shelves will only pull out so far. If you want to remove a shelf completely, pull it forward as far as it will go, raise the front edge and lift it out. To put the shelf into a different position, keep the front edge raised, slot the shelf on to the runner, lower the front edge and slide the shelf in.

For the best results from the main oven we recommend that you use a baking tray which is 310mm (12") square. If you use a tray or tin which is larger than this, you may need to turn it around during cooking. The size of tray which should be used in the second oven should not be bigger than 310mm x 230mm (12" x 9"). Place the longest side parallel with the door. Place single dishes on the centre of the shelf. You may need to turn large items around during cooking. Turn all food round in the second oven.
