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.

Using the fridge
To start the fridge and thermostat control
Turn the thermostat control knob to the desired position. 1 : The lowest position of the thermostat control knob results in the highest temperature inside the appliance. 6 : The highest position of the thermostat control knob results in the lowest temperature inside the appliance. 0 : Off. Allow the appliance to run for a period of 24 hours whenever the temperature setting is changed. This will allow the temperature to stabilise inside the appliance.
Temperature inside the fridge
A suitable temperature inside the fridge is approx. +5°C. If the thermostat control is set too cold, food with a high water content may start to freeze if it has been placed in the coldest places in the fridge. (+ warm, - cold) Meat, fish and milk should be put in the coldest part of the cabinet. The temperature will be affected by: · How often the door is opened · How much food is stored · Position of the appliance (See the Installation section.)

Measuring the temperature
If the temperature is measured using a standard, single thermometer, this should be put in a glass of water centrally placed inside the appliance. This will reflect the temperature inside the food products. Do not place the thermometer hanging or lying directly on the shelf.
· · · ·
Distribute foodstuffs to allow cold air to circulate freely between the products. Do not place food products directly against the cooling plate on the rear wall as they may freeze here. Also never put warm products into the appliance. Wait until they have cooled down. Cover all foods properly to avoid odours and flavours from tainting other food.
Switching off
Set the thermostat control knob to the "0" position. Unplug the power supply plug from the wall socket.
