7. Troubleshooting
| Problem | Possible Cause | Solution |
| Device does not power on. | No power or faulty USB connection. | Ensure the device is securely plugged into a working 5V USB power source. Try a different USB port or power adapter. |
| Cannot pair in Receiver Mode. | Bluetooth not enabled on phone/tablet; device not in pairing mode; too far from device. | Ensure Bluetooth is enabled on your source device. Confirm the YET-TR6 red LED is flashing (RX pairing mode). Move your source device closer to the adapter. |
| No audio in Transmitter Mode. | Audio cable not connected correctly; incorrect audio output selected on source device; Bluetooth headphones/speaker not paired or not in pairing mode. | Verify the 3.5mm audio cable is firmly connected to the adapter's TRANSMIT port and the source device's audio OUTPUT. Check your source device's audio settings. Ensure your Bluetooth headphones/speaker are on and in pairing mode, and the blue LED on the adapter is solid. |
| Poor audio quality or intermittent connection. | Interference; distance too great; low battery on connected Bluetooth device. | Reduce the distance between the adapter and the connected Bluetooth device. Avoid obstacles. Ensure connected Bluetooth devices are sufficiently charged. Avoid strong electromagnetic interference. |
