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.
Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

THE TIMER
Please note that this is a 24 hour clock, for example 2.00 pm is shown as 1400. In the following pages we explain how to set the controls. Read through them a few times until you are familiar with the procedure. If the oven is switched off on the wall, or there is a loss of power, the clock will stop and you will not be able to use the ovens. When you first switch the electricity supply on, the timer display will flash. Cookpot symbol Bell symbol

TO SET THE TIME OF DAY
Turn the selector knob to 'Manual' then turn to 'Time Setting'. Set the correct time by turning and holding the setting knob clockwise. Adjust the time by turning the setting knob in either direction. Turn the selector knob back to 'Manual'.
TO USE THE COUNTDOWN
Turn the selector knob to 'Countdown'. Turn the setting knob clockwise until the display shows the time you want. The bell symbol ( ) will be showing and this will stay lit up during the time. Our diagram shows the timer set to 5 minutes. If you change your mind and want to cancel the time you have set, simply turn the setting knob anticlockwise. Then turn the selector to 'Manual'. When you are using the countdown you can make the clock show the time of day by turning the selector knob to 'Manual'. The bell symbol will stay on to remind you that the countdown is set. At the end of the timed period an alarm will sound and the bell symbol will go out. Switch off the alarm by turning the selector knob to 'Time Setting'. Then turn to 'Manual' and the time of day will show in the display.
Note:
You can use the countdown when an automatic sequence has been set, as long as you remember the following point. 1 Turn the selector knob to 'Automatic' as soon as you have entered the timed period into the display.
