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.

Connecting the satellite speakers
% Speaker layout
When positioning the speakers, to obtain the best possible sound from this system you need to place all satellite speakers at the same distance from the listening position with the front of each speaker facing toward the listener.
When you cannot place them at the same distance from the listening position, you can make adjustment so that speakers operate as if they are placed at the best position. (A pg. 48) A Front left Front right
� Normally place the powered subwoofer in front of you. (Since bass sound is non-directional, you do not need to place it at the same distance as the other speakers.) NOTE
� Although the satellite speakers and the powered subwoofer are magnetically shielded, the TV screen may appear mottled. In this case, keep the distance between them to the TV to over 10 cm. � For safety reasons, always ensure that there is sufficient space behind the powered subwoofer. � When you position the satellite speakers in a relatively high place, such as the top of your bookshelf, place them on a flat and level surface. � Be sure to place the powered subwoofer to the TV�s right. If you place the powered subwoofer to the TV�s left, keep sufficient distance between them to prevent the TV from appearing mottled.
