3. Setup
- Insert Batteries: Open the battery compartment and insert the two included AAA batteries, ensuring correct polarity.
- Power On: Press and hold the power button (red button) until the LCD screen illuminates.
- Warm-up: The device will undergo a 30-second warm-up period. During this time, the bar graph on the LCD will cycle, and you will hear a tone. Wait until the tone stops and the bar graph stabilizes before proceeding.
- Select Sensitivity: Press the 'S' button (green button) to toggle between high and low sensitivity modes. The display will indicate the selected mode.

4. Operating Instructions
Once the device has completed its warm-up and you have selected the desired sensitivity, you can begin detecting gas leaks.
- Detection Process: Slowly move the sensor tip of the detector close to areas where you suspect a gas leak, such as gas pipelines, appliance connections, or gas storage tanks.
- Interpreting Alerts:
- If gas is detected, the device will emit an audible alarm (75dB) and the visual bar graph on the LCD will increase, turning red at higher concentrations.
- The response time is approximately 0.5 to 2 seconds.
- Action on Detection: If a gas leak is detected, immediately turn off the gas supply, open windows and doors for ventilation, and evacuate the area. Do not operate electrical switches or phones. Contact your gas provider or emergency services.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly inserted batteries. | Replace batteries with new AAA batteries, ensuring correct polarity. |
| No gas detection or inconsistent readings. | Warm-up not complete, sensor obstructed, or low battery. | Ensure warm-up is complete. Clean the sensor tip. Replace batteries if low. |
| False alarms. | Presence of other volatile organic compounds (VOCs) like alcohol, acetone, or strong cleaning agents. | Ensure the testing area is free from other VOCs. Test in a well-ventilated area. |
