8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power or loose connection. | Check if the USB Type-C cable is securely connected to both the fan and the power source. Ensure the power source is active. |
| Fan is not cooling effectively. | Blocked air vents or incorrect temperature setting. | Ensure air vents are clear of obstructions. Verify the cooling temperature is set appropriately (e.g., lower temperature for more cooling). |
| Fan feels loose on the camera. | Mounting clip not secure or incompatible. | Ensure the correct mounting clip is used for your camera model and that it is securely fastened. If the attachment remains loose, consider using additional securing methods (e.g., a hair tie or strap) to prevent accidental detachment during movement. |
