4. Operação
4.1 Exibiçãoview
The large color display provides a comprehensive view of current air quality parameters:
- Concentração de CO2 (PPM): Central large number, indicating parts per million.
- Temperatura: Displayed in Fahrenheit or Celsius.
- Umidade: Exibido como uma porcentagemtage.
- Tempo: Hora atual.
- Status do alarme: Icons indicating active alarms.
- Indicador de bateria: Mostra a autonomia restante da bateria.

4.2 Understanding CO2 Levels
The device categorizes CO2 concentration into three stages, indicated by color changes on the display and corresponding icons:
- S normaltage: CO2 ≤ 800 ppm (Green indicator). Indicates good air quality.
- Warning Stage: CO2 801 - 1600 ppm (Yellow indicator). Suggests ventilation may be required.
- Dangerous Stage: CO2 > 1600 ppm (Red indicator). Indicates poor air quality; immediate ventilation is recommended.

4.3 Configurar alarmes
The LFF CO2 Detector features customizable dual alarms. When the measured CO2 level reaches your set high or low alarm threshold, an audible beep will sound, and the alarm icon will flash. Refer to the device's on-screen menu or specific buttons (usually labeled 'SET' or 'MODE') to adjust the CO2 alarm values.

4.4 Ajuste de luz de fundo
The device offers three levels of backlight brightness (100%, 50%, 0%) to suit different lighting conditions and conserve battery life. Use the designated button (often indicated by a light bulb icon) to cycle through the brightness settings.

4.5 Configuração de Hora e Data
To set the current time and date, navigate through the device's menu using the control buttons. Follow the on-screen prompts to adjust hours, minutes, and date. Consult the quick start guide or on-screen instructions for specific button sequences.
5. Manutenção
5.1 Limpeza

6. Solução De Problemas
- Inaccurate CO2 Readings: If you suspect inaccurate readings, take the device outdoors for 10-15 minutes to allow it to recalibrate to ambient CO2 levels (typically around 400-450 ppm). Ensure the sensor vents are not obstructed.
- Bateria de curta duração: Ensure the device is fully charged before use. Adjust the backlight brightness to a lower setting to conserve power. For continuous monitoring, keep the device connected to a power source via the Type-C cable.
- Dispositivo não liga: Check if the battery is charged. Connect the device to a power source and attempt to power it on again. If the issue persists, contact customer support.
- O alarme não soa: Verify that the alarm thresholds are set correctly and that the alarm function is enabled in the device settings.
