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.

Troubleshooting the Docking Station
An error message appears while disconnecting the docking station, even after following the correct procedure for disconnecting the docking station.
Close the software in use, disconnect other devices being used, then try to disconnect the docking station from the computer.
I cannot remove the disc.
You cannot remove the disc when the computer is in power saving mode. Return to normal mode, then press the Eject button.
The disc tray does not eject even after I press the Eject button.
Open the tray by inserting a thin, straight object (such as a paper clip) in the manual eject hole.
