When encountering a non-emergency situation（false alarms occur), you can immediately press the test button and the LED light will flash 10 seconds, indicating that it has entered the silent mode.
• **LCD Digital Screens & Multi-Angle Gas Detection Opening**: The clear LCD screen indicates the current battery status and real-time carbon monoxide concentrations in parts per million (PPM). In the presence of fire or carbon monoxide at levels exceeding 0.1% db/m, the blue indicator lights will blink quickly. Conversely, if carbon monoxide is present, the red indicator will flash. The strategically designed gas detection openings minimize false alarms, providing added peace of mind.
