4. Operating Instructions

4.1 Powering On/Off

To power on the device, press and hold the central button until the display illuminates. To power off, press and hold the central button again until the display turns off.

4.2 Real-Time Monitoring

Upon powering on, the device will immediately begin monitoring air quality. The large LCD display will show real-time readings for:

PM2.5: Particulate matter 2.5 micrometers or less in diameter (µg/m³).
PM10: Particulate matter 10 micrometers or less in diameter (µg/m³).
Temperature: Ambient temperature (in Celsius or Fahrenheit, depending on settings).
Humidity: Relative humidity percentage.

5. Maintenance

5.1 Cleaning

To maintain optimal performance, keep the device clean. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the air inlets on the sides are free from dust and debris. Do not attempt to clean the internal sensors directly.

5.2 Storage

When not in use for extended periods, store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the battery is partially charged before storage to prolong its lifespan.

6. Troubleshooting

Device does not power on:
Ensure the device is fully charged. Connect it to a power source using the USB cable and allow it to charge for at least 30 minutes before attempting to power it on again. If the issue persists, the battery may be defective.
Inaccurate readings:
Ensure the air inlets on the sides of the device are not obstructed by dust or debris. Operate the device in a stable environment, away from strong air currents or direct sources of pollution (e.g., smoke, sprays) that could skew readings temporarily. Allow the device a few minutes to stabilize after powering on.
Display issues (e.g., blank screen, distorted image):
Try restarting the device. If the problem persists, it may indicate a hardware malfunction. Contact customer support for assistance.
Buzzer alarm sounds unexpectedly:
Check the current air quality readings on the display. The alarm indicates that pollution levels have exceeded the set thresholds. If the readings appear normal and the alarm continues, there might be a sensor issue. Refer to the device settings to adjust or temporarily disable the alarm if needed.
