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´s for your help, I already recived these manual from you

Viewing the memory gauge
In the Capture mode, the Overlay bar displays a memory gauge that gives the status of working memory (DRAM) and memory on the memory card. Memory card Working memory Working memory is the memory the camera uses to process pictures. The working memory gauge fluctuates as the camera processes pictures. When the camera has completely processed all pictures, by either saving them to the memory card or deleting them, the working memory gauge will be clear. The memory card gauge shows space used on the memory card in red and space available as white. As the camera processes pictures and saves them to the memory card, more of the memory card gauge fills with red.
