7. Important Notes and Limitations

• This Bluetooth adapter is not compatible with Bluetooth hearing aids.
• It is not suitable for use with musical instruments due to potential latency or specific audio requirements.
• When searching for Bluetooth headphones or speakers to pair in TX mode, ensure those devices are in their active pairing state. If they are already connected to another device (e.g., a mobile phone), they will remain connected to that device after being powered on, preventing the BlitzMax adapter from pairing.
• When two devices are simultaneously connected in RX mode, the adapter only supports the SBC codec.

9. Troubleshooting

If you encounter issues with your BlitzMax BM-BT05, please refer to the following common solutions:

• Device not powering on: Ensure the device is fully charged. Connect it to a power source using the Micro USB cable.

  • Verify that the correct input/output source is selected on your audio system or TV.
  • Reduce the distance between the BM-BT05 and the paired Bluetooth device, and remove any obstacles.
  • If using dual connection in RX mode, remember only SBC codec is supported, which might affect quality compared to aptX.
• Intermittent connection:
  • Ensure there are no strong Wi-Fi signals or other Bluetooth devices interfering nearby.
  • Keep the adapter within the recommended operating range (typically up to 10 meters/33 feet).
