3. Troubleshooting

  • There are mild screeching sound coming from the speaker during use.

Potential Cause: The sound receiver hardware located inside the microphone head is not housed in the correct position.
Solution: Give the metal microphone head a gentle knock on a soft surface (such as a couch cushion), this should bump the sound receiver into the correct position, or unscrew the microphone head and blow air into the receiver and re-adjust its position so it does not have direct contact with the inner surface of the microphone head.

  • You can not find/connect to the Legend 2 with your Bluetooth device.

Potential Cause: The Legend 2 is still connected to the previous Bluetooth device.
Solution: Please disconnect the Legend 2 from your Bluetooth device if you wish to have it connected to another Bluetooth device instead.
