1) make sure you logitech gaming software is up to date
2) open the software and where the devices are listed, scroll till you find the icon of a keyboard with what looks like a smartphone on it's side. This is the applet screen
3) select the ff14 applet in the left window
4) in the right window uncheck the box next to LED backlighting.
There is no update for my logitech gaming software and there is no FF14 app to be found...
