- Connect the other end of the 3.5mm audio cable to the audio output interface of your non-Bluetooth device (e.g., TV headphone output, PC audio out, MP3 player).
- Ensure your Bluetooth headphones or speakers are in pairing mode and within 10 meters (33 feet) of the B6 unit.
- Short press the multi-function button on the B6 unit. The blue Bluetooth status indicator light will flash rapidly, indicating it is searching for Bluetooth devices.
- Once connected successfully, the blue Bluetooth status indicator light on the B6 will flash slowly.
- Note: If the B6 connects to an unintended Bluetooth device, short press the multi-function button again to switch to the next available Bluetooth device.
Important Tips for TX Mode:
- Search and connection times may vary due to differences in Bluetooth device programs and protocols.

7. Troubleshooting
If you encounter any issues with your B6 unit, please refer to the following troubleshooting steps. If the problem persists, contact your local dealer for assistance. Do not attempt to disassemble or repair the device yourself to avoid damage or voiding the warranty.
- Device not powering on or working normally?
- Check if the adapter is powered on (long press button for 5 seconds).
- Insert the charger to check if the battery has sufficient power.
- Turn off the adapter, then turn it on again to see if it resumes normal operation.
- Cannot connect to a specific Bluetooth device or unexpected device connects?
- If multiple Bluetooth devices are paired, the B6 may prioritize the first one found. Cancel pairing with unused devices.
- Ensure the B6 is close to the target Bluetooth device (within 10m/33ft).
- In Transmitter Mode, short press the multi-function button to cycle through available Bluetooth devices.
- If pairing fails, power off both the B6 and the Bluetooth receiving device, then try pairing again.
- Note that differences in Bluetooth chip solutions and transmission protocols between devices can sometimes affect pairing.
- Incorrect operating mode (Receiver vs. Transmitter)?
- Verify that the 3.5mm audio cable is inserted into the correct jack: "RECEIVE" (green) for Receiver Mode, "TRANSMIT" (red) for Transmitter Mode.
- The device defaults to Receiver Mode upon power-on. If both audio jacks have cables inserted, it will still default to Receiver Mode.
- Confirm the operating mode by observing the corresponding red indicator light (RECEIVE or TRANSMIT).
- Audio quality issues?
- Avoid using the 3.5mm Bluetooth transmitter-receiver while charging if you experience noise, as this can sometimes introduce interference.
