Troubleshooting
If you encounter issues with your BTR1 Bluetooth Receiver, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power adapter not connected or faulty. | Ensure the 5V DC power supply is securely connected to the unit and the AC outlet. Try a different outlet. |
| Cannot pair device | Bluetooth not enabled on source device; BTR1 not in pairing mode; device too far. | Ensure Bluetooth is enabled on your device. Confirm the BTR1 is powered on and its indicator light is flashing (pairing mode). Move your device closer to the BTR1. |
