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.

Place the end of the inlet hose and that of the emergency emptying hose in a bowl placed on the floor and let the water drain out. � Screw the water inlet hose back on and put the emergency emptying hose back in its place after having screwed the cap on again.
When you intend to start the machine up again, make sure that the room temperature is above 0°C.
