1. Introduction to Radon and Your Detector
Radon is a naturally occurring radioactive gas that is invisible, odorless, and tasteless. It can accumulate in homes and buildings, posing a significant health risk, primarily lung cancer. Continuous monitoring of radon levels is crucial because these levels can fluctuate daily due to various environmental factors.
The Funny Kitchen HRDM-02B Home Radon Detector provides accurate, real-time measurements of radon gas, allowing you to monitor your home's air quality and take necessary actions to mitigate high levels. This manual will guide you through the setup, operation, and maintenance of your device.
This image illustrates the health risks associated with radon gas, including its contribution to lung cancer, and how it can enter a home from the ground.
2. Product Overview
The HRDM-02B Radon Detector is designed for ease of use and reliable performance. Key features include:
- Long-Term Monitoring: Provides continuous readings to track radon level fluctuations over time.
- Short-Term Monitoring: Offers quick indications of current radon levels, useful for assessing the impact of mitigation efforts.
- Rechargeable Battery: Powered by an internal rechargeable battery for portable and low-consumption operation.
- No Lab Fees: Delivers immediate results without the need to send samples to a lab.
- User-Friendly Display: Clear on-screen display of both long and short-term average radon levels.
This image provides a detailed view of the radon detector's screen, highlighting the 'Long Term Average' and 'Short Term Average' readings, along with indicators for low battery, active status, and the measurement unit (pCi/L).
3. Setup
3.1 Unpacking and Initial Charge
- Carefully remove the radon detector from its packaging.
- Locate the USB charging port on the side of the device (refer to image below).
- Connect the detector to a standard USB power adapter (not included) using a compatible USB cable (not included) to fully charge the internal battery before first use. The device is powered by an internal rechargeable battery.
- Turn the device ON using the ON/OFF switch located next to the USB port.
3.2 Placement Guidelines
For accurate readings, place the detector in a suitable location:
- Place the device 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 8 inches (20 cm) from any walls.
- Avoid placing it near drafts, vents, windows, doors, or in direct sunlight.
- Do not place it in high-humidity areas like bathrooms or laundry rooms.
- For comprehensive monitoring, consider moving the device to different rooms over time (e.g., baby's room, living room, office, basement) as radon levels can vary.
This image displays the physical dimensions of the radon detector and points out key external features such as the USB charging port and the ON/OFF switch located on the side.
This image demonstrates the versatility of the radon detector, showing it can be used in multiple environments such as residential spaces (baby's room, living room, basement), educational institutions (classroom), and workplaces (office) to monitor radon levels.
4. Operating Instructions
4.1 Understanding the Display
The detector's screen provides two main readings:
- LONG TERM AVERAGE: This value represents the average radon concentration over the entire monitoring period since the last reset. It provides a stable indication of your home's typical radon level.
- SHORT TERM AVERAGE: This value shows the average radon concentration over a shorter, recent period (e.g., 1 day). It is more sensitive to recent fluctuations and can help assess immediate changes or the effectiveness of ventilation.
Both readings are displayed in pCi/L (picocuries per liter), a common unit for radon measurement. The display also includes indicators for low battery and active status.
The detector is shown in a home environment, emphasizing its portability and the importance of continuous monitoring. Icons highlight that initial readings are available within 24 hours, the device uses a rechargeable battery, and radon levels can fluctuate daily.
4.2 First Readings
After turning on the device, it will begin sampling the air. Your first indication of radon levels will typically appear within 24 hours. For a more stable and representative long-term average, allow the device to operate for at least 7 days in a single location.
4.3 Button Functions
The device features two buttons, typically labeled 'R' and 'M', for interaction:
- 'R' Button (Reset): Press and hold this button to reset the long-term average reading. This is useful when moving the detector to a new location or after implementing radon mitigation measures.
- 'M' Button (Mode/Menu): This button may cycle through different display modes or access menu options, if available. Refer to the on-screen prompts for specific functions.

5. Maintenance
5.1 Cleaning
To maintain optimal performance, keep the detector clean:
- Wipe the exterior of the device with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or immerse the device in water.
- Ensure the air inlets and outlets are free from dust or obstructions.
5.2 Battery Charging
The device is powered by an internal rechargeable battery. When the low battery indicator appears on the display, connect the detector to a USB power source using a compatible USB cable to recharge it. A full charge will last for an extended period, ensuring continuous monitoring.
6. Troubleshooting
If you encounter issues with your radon detector, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on or display is blank. | Battery is depleted or device is off. | Ensure the ON/OFF switch is in the 'ON' position. Connect the device to a USB power source to charge the battery. |
| Readings seem inaccurate or show dashes. | Initial calibration period, environmental interference, or sensor issue. | Allow at least 24 hours for initial readings to stabilize. Ensure proper placement away from drafts or extreme conditions. If dashes persist, try resetting the device. |
| Buttons ('R' or 'M') are unresponsive. | Temporary software glitch or physical button issue. | Try turning the device OFF and then ON again. If the issue persists, contact customer support. |
| Low battery indicator persists after charging. | Charging cable or adapter issue, or battery fault. | Try a different USB cable and power adapter. Ensure the charging port is clean. If the problem continues, the battery may need service. |
