Thoughtful brightness design You can choose high, medium, low and off screen brightness settings. The breathing light can also be turned off. Please rest assured that even when the breathing light or screen brightness is turned off, the product continues to detect the CO concentration value in the surrounding environment. Once it exceeds 50PPM, the carbon monoxide alarm indicator and screen will light up quickly, and an alarm sound of more than 85dB decibels will be issued to remind you.
