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

VCR Aerial TV RF-Coaxial cable
Connect all the cables as shown in the illustration, then connect the AC Mains lead (part of the package) to an AC wall outlet. To be able to receive TV programmes it is mandatory to connect the RF-Coaxial cable even if the video recorder is connected by a 21-pin Scart cable.
21-pin Scart cable
If you decide to just use the RF-Coaxial cable to connect the TV set you must adjust the video output channel with the TV set's input channel.
