• To power off: Press and hold the power button again until the display turns off.

4. Operating Instructions

4.1 Display Overview

The 7-inch LED display provides a comprehensive view of all monitored parameters. Refer to the image below for a visual guide to the display layout.

• PM1.0, PM2.5, PM10: Displays particulate matter concentrations in µg/m³. A "GOOD" indicator suggests healthy levels.
• HCHO: Formaldehyde concentration in mg/m³. An "OK" indicator suggests acceptable levels.
• CO2: Carbon Dioxide concentration in PPM (parts per million). A "POOR" indicator suggests high levels.
• TVOC: Total Volatile Organic Compounds concentration in mg/m³. An "OK" indicator suggests acceptable levels.
• TEMP: Temperature reading in °C or °F.
• HUMI: Humidity percentage (%).
• Time: Current time (AM/PM).
• AQI: Air Quality Index, displayed with a color-coded scale (0-50 Good, 51-100 Moderate, 101-150 Unhealthy for Sensitive Groups, 151-200 Unhealthy, 201-300 Very Unhealthy, 301-500 Hazardous).
• Battery Indicator: Shows current battery level.
• Speaker Icon: Indicates alert sound status.

4.2 Parameter Interpretation

Understanding the readings is crucial for maintaining a healthy indoor environment:

• PM2.5/PM10: Fine particulate matter that can penetrate deep into the lungs. Lower values are better.
• HCHO (Formaldehyde): A common indoor air pollutant from building materials and furniture. High levels can cause respiratory issues.
• TVOC (Total Volatile Organic Compounds): A group of chemicals emitted from various products. High levels can cause irritation and health effects.
• CO2 (Carbon Dioxide): High levels can indicate poor ventilation, leading to drowsiness and reduced concentration.
• AQI (Air Quality Index): A standardized scale that combines multiple pollutants into a single number, indicating overall air quality and associated health risks.

4.3 AQI Alerts and Mute Function

The monitor features 7 distinct alert functions for various pollutants and AQI levels. When a parameter exceeds a predefined safe threshold, an audible alarm will sound, and the corresponding indicator on the display may change color (e.g., "POOR" for CO2). To silence an alarm, press the mute button (refer to the device's physical buttons for location, typically a dedicated button or a multi-function button).

4.4 Temperature Unit Selection

To switch between Fahrenheit (°F) and Celsius (°C) temperature units, simply click the 'Power button' once while the device is on. The display will update to show the selected unit.

4.5 Display Brightness Adjustment

The monitor offers three brightness settings for its 7-inch LED display. Consult the device's physical buttons or on-screen menu (if applicable) for instructions on how to cycle through these settings to suit your viewing preference.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the display and exterior of the monitor. Do not use liquid cleaners or abrasive materials, as they may damage the device.
• Sensor Care: To ensure accurate readings, avoid placing the monitor near strong odors, perfumes, aerosols, or areas with high dust concentration, as these can interfere with sensor performance.
• Storage: When not in use for extended periods, store the monitor in a cool, dry place away from direct sunlight and extreme temperatures.
