2. Safety Information

Please read all instructions carefully before installation and use. Failure to follow these instructions may result in property damage, injury, or death.

• This device is designed for indoor use only.
• Do not paint the detector. Paint may clog the openings and interfere with proper operation.
• Do not install in areas with high humidity, excessive dust, or grease.
• Avoid installing near ventilation openings, doors, windows, or areas with strong air currents, as this may affect sensor accuracy.
• Test the detector regularly as described in the "Operating" section.
• In case of an alarm, evacuate the premises immediately and contact emergency services.
• This device is not a substitute for proper maintenance of fuel-burning appliances.

3. Product Overview

The detector features a clear 2.1-inch HD color screen display and three control buttons for easy operation.

Display Elements:

• CO PPM: Displays the concentration of carbon monoxide in parts per million.
• GAS: Bar indicators for combustible gas levels (green, yellow, orange, red).
• Temperature: Shows the ambient temperature.
• Humidity: Displays the relative humidity.
• Icons: Indicators for sound, flame (gas), sun (brightness), and green leaf (normal operation).

Recommended Installation Locations:

• For CO detection, install near sleeping areas and on every level of your home.
• For natural gas detection, install near gas-burning appliances (e.g., kitchen, furnace room).
• Ensure the detector is not obstructed by furniture or curtains.
• Avoid dead air spaces, such as peaks of vaulted ceilings or corners where air circulation is poor.

5. Operating

Once plugged in, the detector will initiate a self-test and begin monitoring. The display will show real-time CO levels, gas levels, temperature, and humidity.

Button Functions:

• "H" Button (Left): Short click to adjust screen light level (brightness).
• "O" Button (Middle): Short click for device testing (alarm sound and display check). Long click to switch temperature units between Celsius (°C) and Fahrenheit (°F).
• "D" Button (Right): Short click to turn the alarm sound on or off.

Alarm Indicators:

The device provides both audible and visual alarms to indicate the presence of dangerous gas levels.

The intelligent power indicator light provides quick status updates:

• Green Light (screen off and indicator light on): Indicates normal operation and continuous gas concentration monitoring.
• Red Light (alarm): Indicates a mute error or sensor malfunction, or an active alarm for detected gas.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your detector.

• Cleaning: Gently wipe the exterior of the detector with a soft, damp cloth. Do not use cleaning agents, solvents, or polishes, as these can damage the unit or interfere with sensor operation.
• Dust Removal: Periodically vacuum or brush the air vents to prevent dust buildup, which can obstruct gas entry to the sensors.
• Testing: Perform a device test monthly using the "O" button to ensure the alarm and display are functioning correctly.
• Sensor Lifespan: Gas sensors have a limited lifespan. While this product is designed for long-term use, consider replacing the unit after 5-7 years for optimal safety, or if it frequently reports malfunctions.
