8. Troubleshooting
If you encounter issues with your GD-02 detector, consider the following:
- Device Not Powering On:
- Ensure the battery is charged. Connect to a power source and allow it to charge for at least 30 minutes.
- Verify the power button is pressed and held correctly.
- Inaccurate Readings/No Detection:
- Ensure the device has completed its warm-up period (approx. 15-16 seconds).
- Check if the probe is positioned correctly near the suspected gas source.
- Ensure the sensor is clean and unobstructed.
- Perform a factory reset if readings seem consistently off (refer to System Settings).
- Alarms Not Functioning:
- Check alarm settings in the General Settings menu to ensure visual, audible, and vibration alarms are enabled.
- Verify alarm thresholds are set appropriately for your detection needs.
- Screen Issues:
- Adjust screen brightness in System Settings.
- If the screen is unresponsive or frozen, try a soft reset by holding the power button until it turns off, then restart.
9. User Tips
