6.1 Oye Ifihan naa

The LED display provides real-time readings for:

• Decibel (dB): Sound level in decibels.
• CO2 (ppm): Carbon Dioxide concentration in parts per million.
• Temperature (℃): Ambient temperature in Celsius.
• Ọriniinitutu (%): Ojulumo ọriniinitutu ogoruntage.

The display also features color-coded smiley patterns to visually indicate the general air quality status, changing from green (good) to yellow (moderate) to red (poor) based on detected levels.

6.2 Siṣàtúnṣe iwọn LED Imọlẹ

The LED screen brightness can be manually adjusted to suit different lighting conditions. Refer to the device's physical buttons (usually labeled 'Brightness' or indicated by an icon) to cycle through brightness levels.

6.3 CO2 Auto-Calibration

The device is equipped with an automatic CO2 calibration function to maintain measurement accuracy. For optimal performance, ensure the device is exposed to fresh outdoor air periodically, or follow specific instructions in the device's menu for manual calibration if available.

6.4 Setting CO2 Alarm Thresholds

The device provides an automatic alarm when CO2 levels exceed a preset threshold. You can manually adjust this threshold between 800ppm and 2000ppm. Consult the device's menu or control buttons for instructions on how to access and modify this setting.

6.5 Alarm Sound Control

The audible alarm can be manually turned on or off. This allows customization based on user preference and environment. Locate the dedicated button or menu option for alarm sound control.
