The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
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.
Great price, Quick delivery, the document was very usefull A+++++++++++++++

Caring for Your Cooktop
Sealed surface burners and cooktop
To clean the burners:
1. Pull the burner caps straight up from the burner base. 2. Clean the burner caps with warm, soapy water and a sponge. You can also clean the caps with a mildly abrasive plastic scrubbing pad and powdered cleanser. Do not clean the burner caps in a dishwasher or self-cleaning oven. 3. If the gas tube opening has become soiled or clogged, use a cotton swab or a soft cloth to clean the area. 4. If the ports are clogged, clean them with a straight pin. Do not enlarge or distort the port. Do not use a wooden toothpick. If the burner needs to be adjusted, call a qualified technician for service. 5. After cleaning the gas tube opening and ports, replace the burner caps. To replace the burner caps, make sure the alignment pins on the burner base are properly aligned with the cap.

6. Turn on the burner to see if it will light. If the burner does not light after you have cleaned it, contact a KitchenAid designated service technician. Do not service the sealed burner yourself.
