4. Setup
4.1 Initial Charging
Before first use, fully charge the device using the provided USB Type-C cable and a compatible USB power adapter (not included). The battery indicator on the display will show charging status. Avoid using the device while charging or when the battery is low, as this may affect data accuracy.
4.2 Powering On/Off
- To Power On: Long press the power button located on the side of the device.
- To Power Off: Long press the power button again.
4.3 Initial Calibration
Upon first power-on, the device will initiate a countdown (e.g., from 400 seconds) to calibrate its sensors. Allow this process to complete for accurate readings. During this time, the CO2, HCHO, and TVOC readings may display dashes until calibration is finished.

5.4 Air Quality Pollution Level Reference Table
Refer to the table below for general guidelines on air quality status based on detected gas levels:
| Air Quality Status | CO2 | TVOC | HCHO | PM2.5 |
|---|---|---|---|---|
| Good Air Quality (Green) | ≤600ppm | ≤0.6mg/m³ | ≤0.08mg/m³ | ≤75ug/m³ |
| Moderate Air Quality (Yellow) | >600ppm; ≤1000ppm | >0.6mg/m³; ≤1.6mg/m³ | >0.08mg/m³; ≤0.12mg/m³ | >75ug/m³; ≤150ug/m³ |
| Poor Air Quality (Red) | >1000ppm | >1.6mg/m³ | >0.12mg/m³ | >150ug/m³ |
