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.

Operating Instructions
Before using for the first time
Setting/Changing the Time
The time display will flash after the electrical supply is connected. You must then first set the time. If the time has not been set, the oven cannot be switched on.
Setting the Time
0 1. Press the M button.
2. Set the current time within 5 seconds using the + or - buttons. The time appears in the display. The oven is now ready for use.
3
By pressing the + or - button for more than 2 seconds, the minutes will start to run forwards or backwards until the button is released again. By this means you can reach the required setting quicker. If the appliance has been isolated from the mains, e.g. due to a power failure, the time display will flash again. In this case reset the time again, as described above.

Changing the Time
If you wish to correct the time, e.g. on the change over from summer to winter time, repeat the process described under �Setting the Time�.
