5. Настройка
5.1 Першапачатковая зарадка
Before first use, fully charge the device using the provided Type-C charging cable and a 5V-1A USB adapter (not included). The built-in 2400mAh Lithium battery provides portable operation, but for continuous monitoring, it is recommended to keep the device connected to power due to the multiple sensors.

5.2 Уключэнне/выключэнне
Націсніце і ўтрымлівайце Кнопка харчавання on the back of the device to turn it ON or OFF.
5.3 Размяшчэнне
Place the CO2 meter in the area you wish to monitor. For accurate readings, avoid placing it directly in front of air vents, windows, or in drafty locations. The device can be placed on a flat surface or mounted on a wall using the integrated hanging hole.

6. Аперацыя
6.1 Чытанне паказанняў на дысплеі
Once powered on, the large LCD will display the current CO2 concentration in parts per million (ppm), temperature in degrees Fahrenheit or Celsius, and relative humidity percentage.
6.2 CO2 Concentration Levels
The device categorizes CO2 levels into three stages, indicated by visual cues on the display and potentially an alarm:
- Нармальны: 400-700 ppm (Good air quality)
- Папярэджанне: 700-1500 ppm (Moderate air quality, ventilation recommended)
- Небяспечна: 1500-5000 ppm (Poor air quality, immediate ventilation required)

Image: The CO2 meter display illustrating the three stages of CO2 concentration: Normal (400-700 ppm), Warning (700-1500 ppm), and Dangerous (1500-5000 ppm).
6.3 Функцыя сігналізацыі
The CO2 detector is equipped with an audible alarm that activates when the detected CO2 concentration exceeds a preset value. You can customize this alarm threshold.
- Setting Alarm Value: Double-press the power button to enter the alarm setting mode. Use the UP and DOWN buttons to adjust the desired CO2 threshold.
- Toggling Alarm ON/OFF: Press the UP button on the back panel to enable or disable the audible alarm.

6.4 Каліброўка
To ensure the accuracy of measurements, the CO2 meter supports a calibration function. It is recommended to calibrate the device in an open, fresh air environment, especially when using it for the first time.
- Ручная каліброўка:
- Выключыце прыладу.
- Take the device to an open outdoor environment with fresh air.
- Simultaneously press and hold all three buttons (UP, Power, DOWN) on the back of the device.
- The display will show a 200-second countdown. Keep the device still and do not breathe near it during this period.
- Calibration will complete automatically after the countdown.
- Аўтаматычная каліброўка: The automatic calibration function is off by default. If turned on, the first self-calibration occurs 24 hours after power-on, and subsequent self-calibrations occur every 7 days. If the device is turned off and on again, the timer for self-calibration will reset.
