How to Change the Screen Brightness on Performance Box Touch

You can adjust the brightness of the Performance Box Touch screen by pressing the Settings button at the bottom left of the screen. Use the Forward arrow or swipe left to navigate to the General Settings menu.
 

The screen brightness has 5 settings, 1 is the dimmest and 5 is the brightest. 

You can also use the 'Auto' setting. This uses the internal ambient light sensor to automatically adjust the screen brightness. In dark conditions, the screen brightness will dim, and in light conditions, the screen will brighten.
