2. Setup and Initial Use

2.1 Charging the Device

The air quality detector is equipped with a 1500mAh rechargeable lithium battery. Before first use, or after prolonged storage, ensure the device is fully charged. Use the provided Type-C cable to connect the monitor to a USB power source (USB wall charger not included). A full charge can provide up to 8 hours of operation.

2.2 Initial Calibration

For accurate readings, it is crucial to perform an initial calibration. Place the monitor in a well-ventilated indoor environment for at least 1 hour before its first use or after long-term storage. This allows the sensors to stabilize and ensures data accuracy.

2.3 Powering On/Off

To power on the device, press and hold the power button located on the side. The LCD screen will illuminate. To power off, press and hold the power button again.

3. Operation

3.1 Understanding the Display

The large LCD color screen displays real-time readings for various air quality parameters. The display is designed for easy interpretation with color-coded indicators for overall air quality:

• Good (Green): Indicates healthy air quality.
• Slight Pollution (Yellow): Suggests minor air quality issues.
• Moderately Pollution (Red): Indicates significant air quality concerns.
• Severe Pollution (Purple): Signifies hazardous air quality levels.

Individual gas concentrations (HCHO, TVOC, PM2.5, CO, CO2), temperature, and humidity are displayed numerically. The AQI (Air Quality Index) provides an overall assessment.

4. Maintenance

4.1 Cleaning

To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the vents are clear of dust and debris for optimal performance.

4.2 Storage

When not in use for extended periods, store the monitor in a cool, dry place away from direct sunlight and extreme temperatures. If storing for a long time, ensure the battery is partially charged to prolong its lifespan.

4.3 Important Sensor Information

The sensors within this product are sensitive and can be influenced by various environmental factors. When using the device, ensure that there are no volatile substances with irritating odors present in the room. These include, but are not limited to, alcohol, perfume, benzene, toluene, acetic acid, hydrogen sulfide, and carbon monoxide. Such pungent odors can affect or even damage the sensors, leading to inaccurate detection readings.
