5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is off. | Power saving mode is active, or no power connection. | Make a sound (e.g., clap) to activate the display. Ensure the USB cable is securely connected to a power source. |
| Temperature reading is inaccurate. | Environmental factors or sensor calibration. | Ensure the clock is not placed near heat sources, direct sunlight, or air vents. Allow time for the sensor to stabilize in a new environment. Note that minor variations may occur. |
