Turning on and off the keyboard backlights is easy! Most keyboard models will have a key along the special function key rows with one of two symbols below:
Pressing the 'FN' key + the backlight key will turn on the backlights. Pressing them again will turn off the backlights.
NOTE: The backlights will automatically turn off after a couple seconds if not used to preserve the keyboard's battery. Begin typing again to activate them.
Pressing the backlight key alone will cycle the backlight brightness from low, then middle, then high.
Pressing the backlight key and the right or left direction key at the same time to cycle through the colors - White, Red, Amber, Green, Aqua, Blue and Violet.
