5. Suidhich
The HAKINAKU HD18 detector is designed for simple plug-and-play operation.
- Tagh àite: Select an AC outlet in areas such as bedrooms, kitchens, living rooms, or basements. For optimal CO detection, place the detector at chest height. For combustible gas, place it closer to the floor if the gas is heavier than air (e.g., propane) or closer to the ceiling if lighter than air (e.g., natural gas). Avoid placing near windows, doors, or ventilation openings that could interfere with readings.
- Dèan ceangal: Insert the detector into a standard 110V to 240V AC outlet.
- Calibration: The detector will automatically begin a self-calibration process upon first power-up. This typically takes a few minutes. During this time, the screen may display a countdown or initialization sequence.
- Deiseil airson a chleachdadh: Once calibration is complete, the screen will display real-time CO ppm, gas status, temperature, and humidity readings, indicating the device is operational.
