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.

Maintenance and cleaning
Clean the external surfaces of the machine and control panel with a damp soft cloth. If necessary use only neutral detergents. Never use abrasive products, scouring pads or solvent (acetone, trichloroethylene etc....). Ensure that the seals around the door, the detergent and rinse aid dispensers are cleaned regularly with a damp cloth. We recommend the use of Finish Dishwasher Cleaner every 3 months or run a 65Â°C wash programme without dishes using detergent. Regular use of Finish Dishwasher Cleaner cleans inaccessible parts, eliminates unpleasant food odours and helps prevent the build-up of limescale.
Under no circumstances may the dishwasher be used without filters. Incorrect repositioning and fitting of the filters will produce poor washing results.
NEVER try to remove the upper spray arm. If residues of soil have clogged the holes in the upper spray arm, remove them with a toothpick.
Cleaning the filters
The filters must be checked and cleaned from time to time. Dirty filters will degrade the washing result. 1. Open the door, remove the lower basket. 2. The dishwasher filter system comprises a coarse filter (A), a microfilter (B) and a flat filter (C). Unlock the filter system using the handle on the microfilter, and remove.
Prolonged periods of non-operation
If you are not using the machine for any period of time you are advised to: 1. Unplug the appliance and then turn off the water. 2. Leave the door ajar to prevent the formation of any unpleasant smells. 3. Leave the inside of the machine clean.
Avoid placing the machine in a location where the temperature is below 0Â°C. If this is unavoidable, empty the machine, close the appliance door, disconnect the water inlet pipe and empty it. 3. Turn the handle about 1/4 a turn anticlockwise and remove.
Moving the machine
If you have to move the machine (moving house etc....): 1. Unplug it. 2. Turn the water tap off. 3. Remove the water inlet and discharge hoses. 4. Pull the machine out together with the hoses. Avoid over tilting the machine during transportation.
4. Take hold of the coarse filter (A) by the handle with the hole and remove from the microfilter (B). 5. Clean all filters thoroughly under running water. 6. Remove the flat filter (C) from the base of the washing compartment and clean both faces thoroughly.
7. Put the flat filter (C) back in the base of the washing compartment. 8. Place the coarse filter (A) in the microfilter (B) and press together. 9. Put the filter combination in place and lock by turning the handle clockwise to the stop. During this process ensure that the flat filter does not protrude above the base of the washing compartment. 14
