Setup
1. Initial Charging
Before first use, fully charge the device. Connect the provided USB-C cable to the monitor's charging port and the other end to the charging adapter. Plug the adapter into a power outlet. The charging time is approximately 5.5 hours. A full charge provides approximately 12 hours of continuous operation.
2. Powering On/Off
- To Power On: Press and hold the power button for approximately 1.5 seconds. The device will emit a single beep, and the screen will illuminate. The sensors will enter a warm-up phase for about 120 seconds. During this countdown, parameter names and units will not be displayed. After the warm-up, all information will appear on the screen.
- To Power Off: While the device is powered on, press and hold the power button for approximately 1.5 seconds. The device will beep once to confirm shutdown, and then turn off.
3. Calibration and Zeroing
For optimal accuracy, especially for HCHO and TVOC sensors, it is recommended to perform calibration and zeroing in a fresh air environment (e.g., outdoors or near an open window) away from potential pollutants.
- Procedure: With the device powered off, press and hold the power button for 4 seconds without releasing. The device will beep twice, indicating entry into calibration and zeroing mode. This process takes approximately 10 to 15 seconds to complete.
Operating Instructions
Understanding the Display
The ultra-high definition color screen displays real-time readings for all monitored parameters. The display is designed for easy readability, showing values for PM1.0, PM2.5, PM10, CO2, HCHO, TVOC, Temperature, Humidity, and current time.

Air Quality Index (AQI) Alarms
The device features 7 AQI alarms to alert you to changes in air quality. When certain pollutant levels exceed predefined thresholds, the monitor will emit an audible buzzer alert. Refer to the on-screen indicators for specific parameter warnings.
Energy Saving Mode
After 30 minutes of continuous operation, the monitor automatically enters an energy-saving mode to conserve battery life. This mode optimizes power consumption while maintaining continuous monitoring capabilities.
Maintenance
Cleaning the Device
To clean the monitor, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure no liquid enters the sensor openings.
Sensor Care
The sensors are delicate components. Avoid exposing the device to extreme temperatures, high humidity, or direct sunlight for prolonged periods. Do not attempt to clean the internal sensors directly.
