5. Setup

5.1 Initial Charging

Before first use, fully charge the detector using the provided Type-C cable. The device is equipped with a 1000mAh rechargeable lithium battery. A full charge takes less than 5 hours, with fast charging completing in under 1 hour. For optimal accuracy, it is recommended to charge the device while it is powered off. Power on the device only after it has sufficient charge.

6. Operating Instructions

6.1 Power On/Off

• Power On: When the detector is off, press and hold the Power button for 2 seconds. The device will initiate a self-test of the screen and sound, followed by a 30-second preheat countdown. After preheating, the device enters the main interface for real-time detection.
• Power Off: From the main interface, press and hold the Power button for 2 seconds. A 3-second countdown prompt will appear. Continue holding until the countdown ends to power off the detector. Releasing the button during the countdown will return the device to the main interface.

6.2 Menu Navigation

To access the main menu interface, long press the 'M' (Function) button while on the main screen. The menu includes options such as F-01 (Gas Zero), F-02 (Gas Calibration), and F-03 (Alarm Threshold Setting).

• Navigate: Press the 'M' key to cycle through the available options.
• Confirm Selection: Long press the 'M' key to confirm your selection.
• Return: Press the '<' key to return to the main interface.
• Auto-Exit: If no action is taken for 10 seconds in the main menu or alarm threshold setting page, the display will automatically revert to the main interface.

6.3 Gas Zero (F-01)

This function is used to zero the gas sensor. It is crucial to perform this process in a clean air environment.

• From the main menu, select 'F-01'.
• A 10-second countdown will begin.
• Upon completion, 'SUCC' will be displayed for a successful zeroing, or 'FRL' for a failed attempt.

6.4 Gas Calibration (F-02)

This function allows for calibration of the CO sensor using a standard gas.

• Introduce a standard gas (e.g., 200 PPM CO) to the detector.
• From the main menu, select 'F-02'.
• Once the displayed value (representing the voltage) stabilizes, press the 'M' key to initiate calibration.
• 'SUCC' will indicate successful calibration, while 'FRL' indicates failure.

6.5 Alarm Threshold Setting (F-03)

You can view and modify the three levels of alarm thresholds.

• View: From the main menu, select 'F-03'. Press the 'M' key to view the three alarm thresholds.
• Modify: Long press the 'M' key to select and modify an alarm threshold. Use the '<' key to change the number of the currently flashing digit. Use the 'M' key to move to the next digit. Once the last digit is modified, changes are saved automatically. Long pressing the '<' key during modification will cancel any changes.
• Important: Alarm thresholds must adhere to the order: Level 1 < Level 2 < Level 3.

6.6 Temperature Unit Switching

From the main interface, click the Power button to switch the temperature unit between Celsius (°C) and Fahrenheit (°F).

6.7 Screen Brightness Switching

From the main interface, press the 'M' (Function) button to cycle through three screen brightness levels (Strong, Moderate, Weak). If no button operations are performed for an extended period, the screen brightness will automatically switch to the lowest level to conserve power. Pressing any button will restore the brightness.

7. Alerts and Alarms

The detector provides visual and audible indications based on detected CO concentration levels:

• Normal Segment: Indicates that the gas concentration is within safe limits. The corresponding indicator segment on the display will be steady.
• Level 1 Alarm (50-100 PPM): When the CO concentration exceeds the set Level 1 alarm threshold, the indicator segment will flash, and the 75 dB buzzer will sound.
• Level 2 Alarm (100-200 PPM): When the CO concentration exceeds the set Level 2 alarm threshold, the indicator segment will flash, and the 75 dB buzzer will sound.
• Level 3 Alarm (≥200 PPM): When the CO concentration exceeds the set Level 3 alarm threshold, the indicator segment will flash, and the 75 dB buzzer will sound. If the concentration exceeds the measurement range (1000 PPM), the display will show '---'.

8. Maintenance

• Regular Calibration: To ensure detection accuracy and reliability, regularly calibrate the device as per the instructions in section 6.4.
• Gas Zeroing: Perform the Gas Zero function (section 6.3) periodically in a clean air environment to maintain sensor accuracy.
• Cleaning: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Sensor Life: The CO sensor has an expected life of 10 years.

9. Troubleshooting

• 'FRL' Displayed During Gas Zero or Calibration: This indicates a failure in the zeroing or calibration process. For Gas Zero, ensure the process is performed in a clean air environment. For calibration, verify that the standard gas concentration is correct and stable. Re-attempt the process.
• '---' Displayed for CO Concentration: This indicates that the carbon monoxide concentration exceeds the maximum measurement range of 1000 PPM. Immediately ventilate the area and take safety precautions.
• Low Battery Reminder: When the battery level is low (one bar remaining), the device will issue a low battery reminder every 2 minutes. The battery icon will flash as a warning, followed by a 10-second countdown to shutdown if not charged.

10. User Tips

• Always charge the detector when it is powered off to prevent inaccurate temperature and humidity readings during charging.
• Perform the 'Gas Zero' function in a fresh air environment to ensure the most accurate baseline reading.
• Take advantage of the magnetic back design to place the detector in convenient, visible locations, especially in tents or vehicles.
• Regularly check the battery level, especially before extended use in camping or travel scenarios, to ensure continuous protection.

11. Safety Precautions

• Always ensure the detector is in normal working condition and operate it strictly according to this manual.
• Regularly calibrate and maintain the device to ensure detection accuracy and reliability.
• If carbon monoxide concentration exceeds safe levels, immediately take action to reduce the concentration and ventilate the area. Avoid prolonged exposure to environments with excessive levels.
• Charge the device only when it is powered off to ensure the accuracy of temperature and humidity sensors.
• Do not expose the device to extreme temperatures, direct sunlight, or moisture.
• Do not attempt to disassemble or repair the device yourself. Contact qualified personnel for service.
