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.

DRAINING RESIDUAL WATER
Draining Residual Water
Residual water should be removed: � before moving a washing machine (relocation), � when installing in areas prone to frost and � before removing the filter. 1.Before emptying the residual water, switch the appliance off and unplug it from the mains socket. Make sure that the water has cooled before draining. 2.Turn the slot through 180°, so that the dot points to the open lock. To do this, use the insert from the detergent dispenser or a coin. The cover bends down to the floor. 3.Remove the hose, place a low container underneath and pull the cap from the hose. 4.Drain the residual water until no more flows out. Then close the residual water emptying hose. 5.Put the hose in the cover, fold the cover up and close the cover using the detergent dispenser insert or a coin. The dot points to the closed lock. 6.Pour about 1 l of water into the detergent dispenser to reactivate the ecosystem. You must also plug the mains plug back into the socket-outlet. 7.Now you can fill the washing machine and run the desired programme.
