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.

External Cleaning
Wash the outer cabinet with warm soapy water. Do NOT use abrasive products. There are sharp edges on the underside of the product so care should be taken when cleaning. Once or twice a year dust the condenser (black grille) and the compressor at the back of the appliance with a brush or vacuum cleaner, as an accumulation of dust will affect the performance of the appliance and cause excessive electricity consumption.
Changing the Light Bulb
Should the light fail to work you can change it as below: Disconnect the appliance from the electricity supply. Remove the lamp cover retaining screws, then take the lamp cover off in the direction of the arrow and the bulb can be changed. (Type of the bulb: 230 V, 15 W, E 14 thread) After changing the bulb replace the lamp cover, and retaining screws and reconnect the appliance to the electricity supply.
Defrosting Your Appliance
The fridge compartment is defrosted automatically, when the motor stops. Defrost water from the cooling plate runs out of the drain and onto a tray on the motor compressor where it evaporates. Droplets of water on the cooling plate during defrosting are quite normal and will freeze on the plate afterwards.
When the appliance is not in use
When the appliance is not in use for long periods disconnect from the electricity supply, empty all of the food and clean the appliance, leaving the door ajar to prevent unpleasant smells.
