5. Maintenance

To ensure the longevity and optimal performance of your Highgaze Bluetooth 5.4 Transmitter BA-55T:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the transmitter to extreme temperatures, humidity, or direct sunlight.

6. Troubleshooting

If you encounter issues with your Highgaze Bluetooth 5.4 Transmitter BA-55T, refer to the following common problems and solutions:

• Device Not Appearing for Pairing: Ensure the transmitter is correctly plugged in and in the appropriate pairing mode (double-click for classic Bluetooth, triple-click for Auracast/LE Audio). Check that your receiving device's Bluetooth is enabled and actively scanning.
• No Audio or Poor Quality Audio: Verify that both the transmitter and receiving device are properly paired and connected. Check the volume levels on both devices. Ensure your receiving device supports the audio codecs (aptX, LC3) being transmitted for optimal quality.
• Auracast Not Working: Confirm that your receiving device is Auracast-enabled. Not all Bluetooth LE devices support Auracast. Ensure you have triple-clicked the transmitter button to enter Auracast mode during pairing.
• Intermittent Connection: Reduce the distance between the transmitter and the receiving device. Avoid physical obstructions and sources of interference (e.g., Wi-Fi routers, other Bluetooth devices).
• Resetting the Device: If the device is unresponsive or exhibiting unusual behavior, press and hold the button on the transmitter for 6 seconds to perform a factory reset.
