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.

OPERATION
Before using
Remove all securing tapes. Wash inside the appliance with lukewarm water and bicarbonate of soda (5 ml to 0.5 litre of water). Do not use soap or detergent as the smell may linger. Dry thoroughly.
Fresh food refrigeration
To obtain the best performance, do not store warm food or evaporating liquids in the refrigerator; do cover or wrap the food, particularly if it has a strong flavour. Do not cover the shelves with any protective material, such as paper, cardboard or plastic, which may obstruct the air circulation through them. To help you use your refrigerator correctly, here are some more useful hints: Raw meat (beef, pork, lamb & wild fowl): wrap in polythene bags and place on the glass shelf above the salad crispers. Meat can only be stored safely in this way for one or two days at the most. Fruit & vegetables: these should be thoroughly cleaned and placed in the bottom salad crispers. Butter & cheese: these should be placed in special airtight containers or wrapped in aluminium foil or polythene bags to exclude as much air as possible. Milk bottles: these should have a cap and should be stored in the bottle rack on the door.
Setting the temperature
The temperature inside the refrigerator is regulated by a thermostat with 6 temperature positions and an �OFF� (O) position. Position 1 = minimum coldness Position 6 = maximum coldness Turn the thermostat dial to the required position. The intermediate position is usually the most suitable (3-4). The thermostat setting can vary as the temperature inside the refrigeration compartment depends on the following factors: � room temperature � how often the door is opened � how much food is stored � position of the appliance
Normal Operating Sounds
Important If the fridge is not defrosting correctly, it is possible that because a very low temperature has been selected, the motor is working continuously, which prevents the defrost cycle from operating. To ensure correct defrosting, a lower number should be selected on the thermostat and you should notice that the motor cuts out from time to time, which is correct. If you wish to return to a lower temperature, turn the thermostat to a higher number, however you should turn the setting lower occasionally to allow automatic defrosting. ¥ You may hear faint gurgling or bubbling sounds when the refrigerant is pumped through the coils or tubing at the rear, to the cooling plate/evaporator. ¥ When the compressor is on, the refrigerant is being pumped round, and you will hear a whirring sound or pulsating noise from the compressor. ¥ A thermostat controls the compressor, and you will hear a faint �click� when the thermostat cuts in and out.
