Keyboard backlighting changes by itself

Your keyboard is equipped with an ambient light sensor that adapts the keyboard backlight according to the brightness of your room.

There are three default levels that are automatically if you do not toggle the keys:

• If the room is dark, the keyboard will set the backlighting to a low level.
• In a bright environment, it will adjust to a high level of backlighting to add more contrast to your environment.
• When the room is too bright, over 200 lux, the backlighting will turn off as the contrast is no longer visible, and it won’t drain your battery unnecessarily.

When you leave your keyboard but keep it on, the keyboard detects when your hands approach and it will turn the backlight back on. The backlighting won’t turn back on if:

• Your keyboard has no more battery, below 10%.
• If the environment you're in is too bright.
• If you've turned it off manually or using Logitech Options software.
