- 2.1'' HD Screen: Displays real-time data dynamically, including CO ppm, smoke indicating bar, combustible gas warning icon, humidity, temperature, CO indicator icon, plug, and alarm status.
- Alarmas audibles y visuales: 85 dB audible alarm and blinking icons for clear alerts.
- Detección sensible: Built-in independent Smoke / CO / Combustible gas sensors for accurate environmental monitoring.
3. Configuración e instalación
3.1 Configuración inicial
- Desembalaje: Retire con cuidado el detector de su embalaje.
- Encendido: Press and hold the power button (usually the central button) for a few seconds to turn on the device. The screen will display a countdown as it calibrates and begins monitoring.

3.2 Recomendaciones de colocación
Proper placement is crucial for effective detection. Consider the following:
- General: Place the detector in areas where gas leaks or smoke are most likely to occur, such as kitchens, near heating appliances, or sleeping areas.
- Altura: For optimal smoke and CO detection, place the unit at a height where it can effectively monitor the air. For combustible gases, which are often heavier than air, consider placing it closer to the floor.
- Evite Obstrucciones: Ensure the detector is not blocked by furniture, curtains, or other objects that could impede air circulation to the sensors.
- Montaje magnético: The detector features a magnetic attachment for easy placement on metallic surfaces like refrigerators. To use, press the button on the back to detach the plug, then attach the magnetic base to a suitable surface.
