DDJ-SX2 : Button lighting is dim

Hello,

I have a ddj sx 2 and it's a great controller but I am just wondering why my cue buttons,master button and all the other buttons are really dim, the only buttons that are bright all the time are the load buttons at the top of the controller and the pad buttons. This makes things a little hard to see when I am playing in low light venues. Is there a setting or something that will increase the brightness ? Please advise thanks
