Backlit is not working. Is there a key I need to press null

F3 and F4 keys are shortcuts for adjusting backlighting levels. The backlighting will not work in a bright environment - the keyboard can sense the lighting in the room that you are in. If you are in a dark room, and the backlighting is not working when you are pressing F4 to increase brightness, there may be an issue with the sensor that detects lighting levels.

Hey! I'd suggest you to get in touch with our Logitech support at https://support.logi.com/hc and the team will look into the issue.
