6. Maintenance

6.1. Cleaning

To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the device or affect sensor performance.

7. Troubleshooting

• Device does not turn on:
  Check if the batteries are installed correctly with the right polarity. Ensure the batteries have sufficient charge. Try replacing the batteries.
• Readings appear inaccurate or fluctuate significantly:
  Allow the device to stabilize for at least 5-10 minutes after powering on, especially in a new environment. Ensure the device is not placed near strong sources of chemicals (e.g., cleaning products, fresh paint) or in areas with high airflow that could interfere with readings.
• Alarm sounds continuously:
  Check the HCHO and TVOC readings on the display. If levels are genuinely high, ventilate the area. If readings appear normal but the alarm persists, try resetting the device using the provided reset pin by inserting it into the reset hole.
• Screen is dim or off:
  Press the Lightbulb Icon Button to toggle the screen backlight. Check battery level and replace if low.
