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.

5. Before mounting the speakers, make sure the attached mounting frame is in the extended position (see Figure 2 on page 4). For each speaker, insert the bottom of the mounting frame (and cable) into its respective cavity. Insert the top of the mounting frame into the opening and slide the baffle up to fit the cutout. Equally tighten each of the four Phillips screws (already inserted) to sandwich the mounting frame against the wallboard, as shown in Figure 4 on page 6.
CAUTION: DO NOT OVERTIGHTEN SCREWS! Doing so may damage the assembly.
