My radio may not be the same as yours but I just
checked and you press the button with "EXPERT"
next to it this allows you to scroll using the <>
buttons to "FAD" then using +and- to set the
front read balance, holding the EXpert button
get you into another menu were you can set
things like News and LW .
this is a picture of my radio
I don't have "expert" button. SRC only
