B is for the config menu (explained below) It will ask you what setting you want, there are four answers (1, 2, ?, and /). 1 is "Precise Side Configuration", it is very simple, just type in any number from 1 to 35 2 is "Precise Color Configuration". It is a bit more complicated. It will ask you 3 questions (color, saturation, and brightness), and all you have to do is type in any desired number from 1-100. ? is a menu of what you type in 2 will look like (photo) / is to remove "?"
