8. Troubleshooting
If you encounter issues with your Bysameyee USB Digital Microscope, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image displayed / Device not recognized | Incorrect connection, missing/corrupt drivers, incompatible device, app not selected. | Ensure the USB cable is securely connected. Install the correct software/drivers for your operating system (refer to Section 6). Verify your Android device supports OTG. Select the microscope as the camera input in your software/app. |
| Image is blurry or out of focus | Improper focus adjustment, incorrect distance from object. | Rotate the focus wheel on the microscope body. Adjust the height of the microscope on its stand to find the optimal working distance. |
| LED lights not working or dim | Brightness wheel setting, power issue. | Adjust the brightness wheel on the USB cable. Ensure the microscope is receiving sufficient power from the USB port. |
| SNAP/ZOOM buttons not working | Operating system limitation, generic app. | The SNAP and ZOOM buttons are primarily designed to function with the dedicated software on Windows systems. They may not be recognized by generic camera apps on Mac or Android. Use the software/app interface for these functions if buttons are unresponsive. |
| Stand is unstable or difficult to adjust | Loose connections, design limitation. | Ensure all parts of the metal stand are securely tightened. For more stable or precise positioning, consider acquiring an alternative, heavier-duty stand if needed for specific applications. |
