1. Einleitung
The Airthings Corentium Home Radon Detector 223 is a state-of-the-art, battery-operated device designed for accurate and continuous monitoring of radon gas levels in your home or other indoor environments. This portable and lightweight detector provides on-screen daily, weekly, and long-term average radon concentrations, empowering you to take informed action for your indoor air quality.
Radon is an invisible, odorless, and radioactive gas that naturally occurs and is found everywhere, impacting air quality. It is the leading cause of lung cancer for non-smokers. Continuous monitoring is essential as radon levels can fluctuate daily due to various environmental factors.

3. Einrichtung
3.1. Auspacken und erste Inspektion
Carefully remove the Airthings Corentium Home Radon Detector from its packaging. Inspect the device for any visible damage. Ensure all components, including the radon sensor and 3 AAA batteries, are present.
3.2. Einlegen der Batterie
- Suchen Sie das Batteriefach auf der Rückseite des Geräts (siehe Abbildung 2).
- Schieben Sie die Batterieabdeckung auf.
- Legen Sie die 3 AAA-Batterien ein und achten Sie dabei auf die richtige Polarität (+/-).
- Schließen Sie die Batterieabdeckung fest.
- The device will automatically power on and begin calibration.
3.3. Platzierung
Place the detector in the lowest lived-in area of your home, such as a basement or ground floor. Ensure it is at least 20 inches (50 cm) from the floor and 4 inches (10 cm) from other objects. Avoid placing it near windows, doors, or ventilation systems that could affect readings.

4. Bedienungsanleitung
4.1. Das Display verstehen
The LCD screen displays two main readings:
- Langfristiger Durchschnitt: This is the average radon concentration since the device was last reset or powered on. This reading becomes more accurate over time.
- Kurzfristiger Durchschnitt: This displays the average radon concentration over the last 24 hours (default) or 7 days. Use the 'Mode' button to switch between these short-term views.
A flashing dot in the upper right corner indicates that the device is actively taking measurements.

4.2. Interpretation der Radonwerte
The device provides guidance on interpreting your long-term average readings:
- 0-2 pCi/L: Continue to monitor.
- 2-4 pCi/L: Ventilate and monitor.
- 4+ pCi/L: Contact a professional and keep monitoring.
It is recommended to monitor for at least 24 hours for initial results, and for 7 days for a more stable long-term average. Radon levels naturally fluctuate with ventilation and weather, so longer measurements provide a more representative average.

4.3. Generating a Radon Report
The Corentium Home allows you to generate a radon self-inspection report. Connect the device to your computer via the micro USB port (located on the side, not included). Follow the instructions provided on the Airthings website to download your data and create a printable report.
5. Wartung
5.1. Batteriewechsel
The device is powered by 3 AAA batteries (included). The battery life is estimated at over 2 years. When the battery indicator on the display shows low power, replace all three batteries with new ones. Refer to section 3.2 for battery installation steps.
5.2. Reinigung
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the device.
5.3. Kalibrierung
The Airthings Corentium Home Radon Detector does not require annual calibrations throughout its useful life, estimated at over 10 years. This is due to its advanced internal architecture and signal analysis algorithms.
6. Fehlerbehebung
6.1. No Display / Device Not Turning On
- Prüfen Sie, ob die Batterien korrekt mit der richtigen Polarität eingelegt sind.
- Ersetzen Sie die Batterien durch neue.
6.2. Inconsistent Readings
- Ensure the device has been running for at least 24 hours for initial readings and 7 days for a stable short-term average. Long-term averages become more accurate over longer periods.
- Verify the device is placed in an optimal location, away from direct drafts, windows, or extreme temperature fluctuations.
- Radon levels naturally fluctuate. Continuous monitoring provides a more representative average.
6.3. Zurücksetzen des Geräts
To clear all historical data and restart monitoring, use a pointed object (like a toothpick) to press the 'Reset' button located on the back of the device (refer to Figure 2). This will reset all averages to zero and begin a new measurement cycle.
