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

Remove all packaging and securing tapes. Wash inside the appliance with lukewarm water and bicarbonate of soda (5ml to 0.5 litre of water). Do not use soap or detergent as the smell may linger. Dry thoroughly.
Starting the Appliance
Insert the plug into the wall socket. When the appliance is connected to the power supply the green indicator light will illuminate.
Green Indicator Light
The green light remains illuminated to indicate that the internal temperature of the appliance is correct for safe storage of frozen food. If the temperature is too high in the appliance the light will go out. The light may go out for the following reasons: There is a power failure The lid has been recently opened A large quantity of food has been added to the appliance There is a fault
The temperature within the freezer is controlled by the thermostat situated on the lower front of the cabinet. To operate the freezer, proceed as follows: When you first start the freezer we suggest that you turn the thermostat to a medium setting by using a coin that fits the groove. The correct setting can be found by measuring the temperature of the top middle package in the freezer. This should not have a temperature warmer than -18Â°C. Min = Lowest setting, minimum cold Max = Highest setting, maximum cold Allow the freezer to run for several hours before placing food inside. Do not fill the freezer to more than 5mm below the top edge.
Opening/Closing the Lid
The lid is fitted with a tightly closing sealing strip to prevent moisture entering the freezer, which could increase the amount of frost formed. When the lid is opened the air inside the freezer becomes slightly warmer and expands. When the lid is closed again the air is cooled immediately. This may lead to the creation of a vacuum which makes it hard to open the lid again immediately. This is quite normal. Wait for a few minutes until the vacuum has equalised and then open gently. Never use excessive force on the handle.
