5. Operating Instructions

5.1 Display Information

The device's display shows the following information:

• CO2 Concentration: Measured in parts per million (PPM).
• Temperature: Displayed in Fahrenheit (°F) or Celsius (°C).
• Humidity: Displayed as a percentage (RH%).
• Indicator Lights: Provide a quick visual reference for CO2 levels (Green: Normal, Yellow: Warning, Red: Danger).

5.2 Button Functions

The device features three control buttons:

• Left Button (Sun Icon): Adjusts display brightness (High, Low, Off). Also used for manual calibration.
• Middle Button (Circle Icon): Switches temperature unit between Fahrenheit (°F) and Celsius (°C). Also used to set CO2 alarm value.
• Right Button (Bell Icon): Toggles the audible alarm on/off.

5.3 CO2 Alarm Feature

The device is pre-set to sound an alarm when CO2 levels exceed 1500 PPM. You can customize this alarm threshold:

1. Press and hold the Middle Button (Circle Icon) for 3 seconds to enter alarm setting mode.
2. Use the Left Button (Sun Icon) to decrease the value and the Right Button (Bell Icon) to increase the value.
3. Press the Middle Button (Circle Icon) again to confirm and exit the setting mode.

6. Manual Calibration

To ensure the most accurate CO2 readings, manual calibration is recommended periodically.

1. Placement: Take the device to a well-ventilated outdoor area with fresh air.
2. Initiate Calibration: Press and hold the Left Button (Sun Icon) for 5 seconds. The display will show a countdown (e.g., "200").
3. Calibration Process: The device will calibrate for approximately 200 seconds.
4. Completion: Once calibration is complete, the screen will display "Calibration ✓". The device is now calibrated and ready for use.

7. CO2 Concentration Levels

The device categorizes CO2 levels into three stages for easy understanding:

• Normal Stage: 400-600 PPM (Green indicator)
• Warning Stage: 700-1499 PPM (Yellow indicator)
• Danger Stage: 1500-5000 PPM (Red indicator)

8. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure the ventilation openings on the device are not blocked to allow for proper air circulation and accurate readings.
• Storage: When not in use for extended periods, store the device in a cool, dry place.
