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.

Notes � Match the timer of the connected source with the unit�s setting. (In the case of the mic input, ensure that the microphone has been connected to the unit.) � Recording starts at the programmed start time, and the power will be switched to STANDBY at the programmed end time. When operation is completed once in the ONCE TIMER mode, the timer programming is cleared. � If digital signals are not supplied when timer recording has been started with digital input signals, �UNLOCK� is displayed and no signals will be recorded. � When using the timer to record a digital satellite broadcast program, for instance, check that the broadcast station with the desired program can be tuned in correctly before programming the timer start and end times.
