[091103]What is "F9BA"?

LaLa

Should user realize and need to know what the "F9BA" is? 
If it doesn't show from the start, why show it now and here in the central as an important title
If it was not important, why show it now?
By the way, the contrast is not enough for text over the image, even the warning below...
even if i change the background image, the problem with the readability...

About the contrast is not enough for text over the image, we will evaluate it. Thanks for your reported.
