5. Maintenance
5.1 Charging
Regularly charge your B4K5 to ensure it is ready for use. While the camera offers up to 11 hours of 1080P recording (with IR and GPS off), actual battery life may vary based on usage (e.g., 4-6 hours at 4K/30fps recording). Always use the provided charging dock or USB-C cable for optimal charging.
5.2 Cleaning
- Use a soft, dry cloth to clean the camera body.
- For the lens, use a specialized lens cleaning cloth and solution to avoid scratches.
- Do not use harsh chemicals or abrasive materials.

6. Troubleshooting
If you encounter issues with your BOBLOV B4K5, please refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Camera does not power on. | Battery may be depleted. Charge the camera fully. Ensure the power button is pressed and held sufficiently. |
| Short battery life. | Recording at 4K resolution or with IR/GPS enabled consumes more power. Ensure the camera is fully charged before use. Battery performance can degrade over time. |
| Recording stops unexpectedly. | Memory may be full (loop recording should overwrite oldest files, but check settings). Low battery can also cause this. Ensure sufficient charge. |
| GPS data not showing. | Ensure GPS is enabled in camera settings. The GPS player software is only compatible with Windows computers. Make sure you are using the correct software. |
| Cannot transfer files to computer. | Ensure the USB-C cable is securely connected. Try a different USB port or cable. The camera should appear as a removable drive; if not, check computer's device manager. |
| Video quality is blurry. | Ensure the lens is clean. Check recording resolution settings; higher resolution provides clearer video. |
