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.

Freezer
When the frost has reached a thickness of up to 4mm it can be removed using a plastic scraper. During this operation it is not necessary to disconnect the appliance from the mains and remove the food. Never use metal tools for this operation. For complete defrosting (once or twice a year) proceed as follows: Turn the thermostat control knob to the «OFF» position (O) or disconnect the appliance from the mains. Remove any food from inside the freezer and fridge, wrap it in several sheets of newspaper and store in a cool,dry place. Leave the door open. Clean and dry thoroughly. Reconnect the appliance to the mains or reset the thermostat to the previous position. After letting the appliance run for a least half an hour, replace the previously removed food into the compartment.

Important
When defrosting the freezer, the fridge is also controlled by the thermostat and will not be operational during this period. A temperature rise of the frozen food packs, during defrosting, may shorten their safe storage life.
