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.

Brightness
Brightness is:
� The amount of light reflected off of the page � Measured on a scale of 1 to 100 (copier paper has a brightness of about 84)
Many catalogs list brightness values for paper, but your eye is generally the best judge. Brighter paper increases contrast with the image: text and graphics
� Look crisper � Reproduce better
Paper that isn't as bright gives a softer effect and can be easier to read for long documents.
