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.

HowYourCompactor Works
The compacting ram does not go to the drawer bottom. You will not see compacting of the first few loadings.
Compaction starts after the drawer is about % full. You may hear a noise when glass breaks. Strong glass bottles may not break at all.
The trash in a full compactor bag will be about �/4 the size of its original bulk.
Bottles or cans not placed in the center may become caught between the ram and the drawer. The Drawer Monitor Switch senses a �mislead� and causes the ram to return to the �up� position without compacting. Load bulky trash, bottles and cans in the center of the drawer.
