4. Configuració
4.1 Càrrega inicial
Before first use, fully charge the device using the provided USB cable. Connect the USB cable to the detector's charging port and a compatible USB power adapter (not included). The device can operate while charging.
4.2 Col·locació
The detector features a portable design with a kickstand and lanyard for flexible placement. Place it in areas where carbon monoxide detection is critical, such as near combustion appliances, in living spaces, or during travel in RVs or tents. Avoid placing it directly next to exhaust vents or in excessively airy locations that might dilute CO concentrations.

5. Instruccions de funcionament
5.1 Encès/Apagat
Press and hold the power button (location typically on the side or back) for a few seconds to turn the device on or off. The display will illuminate upon activation.
5.2 Mostra informació
The 2.2-inch HD display provides real-time readings:
- Concentració de CO2: Large digits indicate carbon monoxide levels in parts per million (ppm).
- Temperatura: Displays ambient temperature in Fahrenheit (℉) or Celsius (℃).
- Humitat: Shows relative humidity as a percentage (%).
- Emoji de comoditat: A visual indicator of air quality and comfort based on CO levels.
- Indicador de bateria: Mostra el nivell actual de la bateria.
Sistema d'alarma 5.3
The detector uses a multi-stage alarm system:
- 0-100 ppm CO: Green indicator light and a smiling emoji. Indicates safe levels.
- 100-200 ppm CO: Yellow indicator light and an expressionless emoji. Serves as a warning.
- 200-500 ppm CO: Red indicator light, a sad emoji, and a continuous 85dB audible alarm. Indicates dangerous levels requiring immediate action.

5.4 Prova del detector
To verify the CO sensor functionality, expose the detector to a source of incomplete combustion, such as smoke from a cigarette or burning paper. The CO concentration on the screen should change, and if levels reach 200 ppm, the alarm will activate. Do not test with car exhaust or in overly ventilated areas, as low CO concentrations may not trigger the sensor.
6. Manteniment
6.1 Neteja
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the sensor vents are clear of dust and debris.
6.2 Cura de la bateria
Recharge the battery when the low battery indicator appears. For optimal battery life, avoid prolonged exposure to extreme temperatures.
7. Solució De Problemes
- El dispositiu no s'encén: Assegureu-vos que la bateria estigui carregada. Connecteu-la a una font d'alimentació USB i torneu-ho a provar.
- Lectures de temperatura/humitat inexactes: Allow the device to stabilize in the environment for several minutes. Ensure it is not exposed to direct sunlight or heat sources.
- CO alarm not activating during test: Confirm the CO source is sufficient and the detector is placed appropriately. Avoid overly airy locations.
- Alarm volume too low: The alarm is rated at 85dB. Ensure there are no obstructions blocking the speaker.
