5. Maintenance

• Keep the adapter clean and free from dust. Use a soft, dry cloth for cleaning.

6. Troubleshooting

6.1. Common Issues & Solutions

• Adapter not working / Driver error on Windows 10/11:
  If your Windows 10/11 system has a built-in Bluetooth function (often labeled "Intel(R) Wireless Bluetooth"), it might conflict with the Zexmte adapter. To resolve this, right-click to disable the existing "Intel(R) Wireless Bluetooth" in Device Manager, then re-plug the Zexmte Bluetooth adapter.
• No Bluetooth devices found:
  Ensure your Bluetooth device is in pairing mode. Check that the Zexmte adapter is securely plugged into a USB port and its indicator light is on. Verify that Bluetooth is enabled in your Windows settings.
• Poor connection or limited range:
  Adjust the external antenna to a different angle (90° or 360° rotation) to optimize signal reception. Ensure there are no major obstructions (like thick walls or large metal objects) between the adapter and your Bluetooth device. Reduce the distance between the adapter and the connected device.
• Cannot connect to Mac OS, Linux, car systems, Xbox, or TVs:
  This adapter is designed exclusively for Windows operating systems (Windows 7/8/8.1/10/11) and cannot be used with other platforms or devices directly.
• Cannot connect to a sound system (e.g., home stereo):
  The adapter functions as a transmitter/receiver for your computer. It can connect your computer to Bluetooth speakers or headphones. It cannot directly add Bluetooth functionality to a non-Bluetooth sound system.

7. User Tips

• For optimal performance, always ensure the external antenna is positioned for the best possible signal. Experiment with different angles.
• If you experience any connectivity issues on Windows 10 or 11, remember to check for and disable any pre-existing integrated Bluetooth drivers (such as "Intel(R) Wireless Bluetooth") in your Device Manager before using the Zexmte adapter.
• Take advantage of the multi-device connectivity to create a fully wireless and organized workspace with your favorite peripherals.
• When transferring files, ensure both devices are within the effective range and that the transfer is accepted on the receiving device.
