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.

Rinse aid is automatically added during the last rinse, ensuring thorough rinsing, and spot and streak free drying. The dispenser, which is positioned inside the door, holds about 110 ml of rinse aid, which is sufficient for 16 - 40 dishwashing programmes, depending upon the dosage setting.
Filling with rinse aid
1. Open the container by pressing the release button (A). 2. Add the rinse aid until the container is completely full. The maximum level for filling is indicated by "max".
Ensure that the lid is closed after every refill. Clean up any rinse aid spilt during filling with an absorbent cloth to avoid excess foaming during the next wash. Only use branded rinse aid for dishwashers. Never fill the rinse aid dispenser with any other substances (e.g. dishwasher cleaning agent, liquid detergent). This would damage the appliance.
Adjusting the dose
According to the finish and drying results obtained, adjust the dose of rinse aid by means of the 6 position selector (position 1 minimum dosage, position 6 maximum dosage). Increase the dose if there are drops of water or lime spots on the dishes after washing. The dose is factory set in position 4. Reduce it if there are sticky whitish streaks on the dishes.
Top up the rinse aid when the indicator (B) becomes clear.
