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.

Cleaning and Maintenance
Before any cleaning switch the oven off and let it cool down. Never use steam or steam machines to clean the appliance. Important! Before carrying out maintenance and cleaning operations, make sure that your oven is disconnected from the mains power supply. Cleaning must be carried out after the oven has cooled down. Wash the enamelled parts with lukewarm water and detergent. Do not use abrasive products, such as steel wool pads, acids etc. since these could damage the various surfaces. Rinse stainless steel parts with water after use, and dry them with a soft cloth or chamois leather. In the case of persistent stains, you can use normal non-abrasive detergents or products specific for stainless steel readily available on the market. Another alternative is a drop of hot vinegar. When cleaning the oven door with the glass top cover use just hot water, taking care to avoid using coarse cloths or abrasive products. The hot acids of fruit (e.g. Iemons, stewed prunes, etc.) leave difficult-to-remove stains on the enamelled surfaces; this inconvenient may remove enamel gloss, but, it does not impair oven operation. Clean the oven thoroughly after use; in this way it will be possible to remove cooking residuals more easily, thus avoiding these from burning the next time the oven is used. Models in stainless steel or aluminium: We recommend to clean the oven door using only a wet sponge and dry it up after cleaning with a soft cloth. Never use steel wool, acids or abrasive products as they can damage the oven surface. Clean the oven control panel following the same precautions.
The Hinged Grill
This appliance is supplied with a hinged grill element, to enable you to clean the roof of the oven easily. Before proceeding ensure the oven is cool and is isolated from the electricity supply. 1. Undo the screws which hold the grill in place (see Fig. 7). When doing this operation for the first time, we recommend using a screwdriver. 2. Then gently pull the grill downward to allow access to the oven roof (Fig.7). 3. Clean the oven roof with a suitable cleaner and wipe dry before replacing the hinged grill element. 4. Gently push up the grill element into place and firmly screw into place the holding nuts. Ensure the grill holding nuts are firmly in place to avoid the grill falling down when in use.
