4. Setup

1. Unboxing: Carefully remove the radon detector, user manual, and charging cable from the packaging.
2. Initial Charge: Before first use, fully charge the device using the provided Type-C charging cable and a compatible USB power adapter (not included). The charging indicator on the screen will show charging status. A full charge takes approximately 3.5 hours.
3. Placement: Place the detector in an area where you suspect radon might be present, such as a basement, living room, or bedroom. For accurate readings, place it on a flat surface, at least 20 inches (50 cm) from the floor and 10 inches (25 cm) from walls. Avoid placing it near drafts, vents, or direct heat sources.
4. Power On: Press and hold the power button (if applicable, otherwise it powers on automatically when charged or connected) to turn on the device. The LCD screen will illuminate.

5. Operating Instructions

5.1 Understanding the Display

The 2.0-inch color TFT screen provides real-time and historical radon concentration data. Key indicators include:

• Current Radon Concentration: Displays the real-time radon level in pCi/L or Bq/m³.
• Last 6h Average: Shows the average radon concentration over the past 6 hours.
• Accumulated Average: Displays the long-term average radon concentration.
• Battery Indicator: Shows the current battery level.
• Alarm Status: Indicates if an alarm is active or if levels are within safe limits.
