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.

CARE AND MAINTENANCE
Defrosting Frost will gradually form on the cooling surfaces and it must not be allowed to become too thick since it impairs the cooling efficiency of the refrigerator. RH030 - RH060 Defrosting of the frost built up on the evaporator starts automatically for 2 hours long in every 24 hours. The defrost water is automatically evaporated by the heat generated by the appliance. After defrosting is completed, cooling will automatically be started again. Defrost water During the defrosting process the water runs through a hose into a container on the back of the refrigerator where it evaporates. This container does not need to be emptied. Cleaning Clean the inside of your refrigerator regularly to keep it fresh and gygienic. Switch off the appliance and pull out the plug. Clean the interior and fittings carefully with a mild detergent in lukewarm water. Never use acidic, abrasive or strongsmelling detergents or wax polishes as these will damage the surfaces and leave an unpleasant smell. The wooden housing should be dusted from time/to/time or wiped down with a damp cloth. The door seal should onlz be cleaned with water and rubbed down with talcum powder from time to time. If possible, the unit should also be dusted occasionallz with a brush or, even better, with a vacuum cleaner. Ensure that the plug is disconnected. Changing the feet RH 060DF Should you wish to install your miniBar, you will not need the 40-mm feet. After having removed the 40-mm feet, you can then re-attach the 12-mm feet, located inside the 40-mm feet, to the front and rear fixing points. The 40-mm feet and the 4 remaining screws should be retained for future use. Changing the lightbulb (If available) If the lightbulb needs changing, pull out the plug and proceed as follows: Press the metal reflector to one side and draw the lamp covering backwards. Replace the bulb and push the covering back into place. A new max. 10-watt bulb can be obtained at any service shop. Longer periods of absence � If you wish to switch off the appliance for a longer period of time, pull out the plug, defrost the refrigerator and clean it carefully. Leave the door open to prevent unpleasant odours from forming.
