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.
Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

Maint enance & Cleaning
Before any maintenance of cleaning work is carried out DISCONNECT the appliance from the ELECTRICITY SUPPLY.
Internal Cleaning
Clean the inside and accessories with warm water and bicarbonate of soda (5 ml to 0.5 litre of water). Rinse and dry thoroughly. Do not use detergents, abrasive powders, highly perfumed cleaning products, wax polishes or cleaning products containing bleach or alcohol. Regularly check the door seals and wipe clean to ensure they are clean and free from debris.
External Cleaning
Wash the outer cabinet with warm soapy water. 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.
Defrosting
The refrigerator automatically defrosts every time the compressor stops. The water is discharged, via the pipe, into a tray located below the appliance, where it evaporates.
Important
To avoid defrost water overflowing into the fridge, periodically clean the water discharge hole in the centre of the V shaped drip collector at the back of the refrigerator compartment behind the salad drawer(s). Use the special cleaner provided which you will find already inserted into the discharge hole. While in operation the ****-star compartment becomes progressively covered with frost. This frost, which acts as an insulator and thus prevents the cold from reaching the food should be removed whenever the thickness of the frost exceeds 6 mm (1/4�). To carry out complete defrosting proceed as follows: 1. Remove any food from inside the ****-star compartment, wrap it in several sheets of newspaper and store in a cool dry place. 2. Turn the thermostat knob to position << 0 >>. To accelerate defrosting, place a bowl of hot water inside the compartment (with a piece of cardboard underneath the bowl as protection). 3. Remove any loose pieces of ice as soon as possible. 4. When defrosting is completed, clean and dry thoroughly.
