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
What appears to be trouble is not always serious. Make sure first ... 1 Power cannot be turned on. * Is the power cord unplugged? 2 When the 2 PLAY button is pressed, tape does not move. * Is the 8 PAUSE button pressed? 3 Playback sound is at a very low level. * Are the batteries run down? * Is the head dirty? 4 The ¶ REC button does not function. * Have the safety tabs of the cassette been broken off? * Is a cassette loaded? 5 The disc is loaded but does not play. * Is the disc upside down? * Is the disc dirty? * Is the disc damaged or warped? * Is the lens dirty? * Is there lens condensation? If so, set the (on/ off) button to the on position and wait one or two hours before use. 6 No sound from the speakers. * Are headphones connected? 7 Since tape speed is irregular, wow and flutter occur. * Is the pinch roller or capstan dirty? * Are the batteries run down? 8 Radio reception is poor and there is much static. * Is the antenna properly adjusted? 9 Remote control is impossible. * Are the batteries in the remote control unit exhausted? * Is the remote sensor section exposed to bright light (direct sunlight, etc.)? Note: When the unit is moved from a cold place of around 0�C to a warm place, it may not operate normally, because moisture has formed inside the deck. Normal operation will be restored after waiting one or two hours.
