I press the setup button and hold. A flashess quickly and goes solid. From there I can't select subsequent menus. What am I doing wrong? It jumps from A to F I believe. Then to K and to L then exits.
I'm not a AR7210BX owner but i recall reading somewhere that the version of the AR7210BX that comes with the Blade 270CFX is partially locked, only some of the parameters are adjustable (so that you can only use it on the 270). This might explain some unexpected behaviour, there again it might be something else altogether.
I never could get along with a bunch of cryptic blinky LEDs as a way to set up a FBL.
