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´s for your help, I already recived these manual from you

Some useful hints for freezing
s s
Normal Operating Sounds
You may hear faint gurgling or bubbling sounds when the refrigerant is pumped through the coils or tubing at the rear, to the cooling 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.

The fresh foods to be frozen must be fresh and of the best quality. The size of each pack should be small enough to ensure that it is used in one go. Small packs freeze more quickly and uniformly and give better results. Frozen food, once thawed, must not be refrozen. Lean food keeps better and longer than fatty food, salt reduces the storage time. Wrap the food in polythene or aluminium freezing bags or foil so that they adhere to the food and provide an airtight seal. Stick a label on each pack showing the contents and date of freezing. This makes it easy to check storage times. The same information can be copied onto the record card in the door. Never place hot food, bottles or cans of fizzy drink in the freezer as they may explode. Containers with a lid must not be filled to the brim. Do not open the door unecessarily often or place extra fresh food in the freezer next to food which is already frozen as this could cause the temperature of the frozen food to rise and its quality and storage life to reduce. In the first compartment, produce must only be stacked up to the mark on the drawer soas to ensure that air circulation is not obstructed.
Thawing
Food can be thawed in a number of ways, depending on the type of food and the size of the packs. Meat, fish and fruit should be thawed in the refrigeration compartment and small pieces of meat or poultry can even be cooked while still frozen, but you must ensure that it is thoroughly cooked through. Vegetables should be directly immersed in boiling water; ready-cooked dishes can be placed directly in the oven in their aluminium wrapping. A microwave oven is particularly suitable for thawing any type of frozen or deep-frozen food: follow the oven instructions, particularly regarding the placement of aluminium wrapping in the oven.
Making ice cubes
The appliance is provided with a plastic ice cube tray. Fill the tray 3/4 full to allow the ice to expand and place in one of the freezer drawers. To turn out the ice cubes simply give the tray a slight twist to release the cubes. 8
