3. Setup
3.1 Charging the Device
Before initial use, ensure the device is fully charged. The JD-3002 is equipped with a built-in 3.7V, 1800mAh lithium battery. Connect the included USB cable to the device's charging port and to a standard USB power adapter (5V, 1000mA recommended). The battery frame on the LCD display will flash when the battery is low, indicating it needs recharging.

4. Operating Instructions
4.1 Understanding the Display
The large LCD display provides real-time readings for all monitored parameters:
Figure 4.1: Detailed explanation of the information displayed on the LCD screen.
- CO2: Carbon Dioxide concentration (350ppm-2000ppm).
- TVOC: Total Volatile Organic Compounds concentration (0.000 mg/m³~2.000 mg/m³).
- HCHO: Formaldehyde concentration (0.000 mg/m³~1.000 mg/m³).
- Temperature: Current ambient temperature (0-90.0°C / 32-194°F).
- Humidity: Current relative humidity (0-99.0%RH).
- Battery Indicator: Shows remaining battery life.
- Environmental Quality: Visual indicator (Excellent, Good, Pollution).
4.2 Button Functions
- Mute Button: Press to toggle the alarm sound on or off. An icon on the display will indicate the alarm status.
- °C/°F Button: Press to switch the temperature display between Celsius and Fahrenheit.
- SET Button: Used to enter or confirm settings. Refer to specific settings instructions if available in future updates.
- '+' and '-' Buttons: Used for navigation or adjusting values within settings menus.
4.3 Environmental Quality Judgment
The device provides a quick assessment of air quality based on the measured values. The display will show one of three levels:
- Excellent: All detection values are lower than the set thresholds.
- Good: CO2 detection value is higher than 50ppm, TVOC higher than 0.01 mg/m³, or HCHO higher than 0.03 mg/m³.
- Pollution: CO2 detection value is higher than 100ppm, TVOC higher than 0.02 mg/m³, or HCHO higher than 0.06 mg/m³.
These thresholds are indicative and provide a general guide to air quality.
