7. Troubleshooting
- No Power/Blue Indicator Off: Ensure the USB-A connector is securely plugged into a working USB power source. Check if the power source is active.
- Cannot Find "Vention-NAI" in Bluetooth List: Make sure the adapter is powered on. Try restarting your phone's Bluetooth or the adapter by unplugging and re-plugging it. Ensure no other device is currently connected to the adapter.
- No Sound After Connection: Verify that your car stereo or speaker system is set to the correct AUX input. Check the volume levels on both your phone and the audio system. Ensure the 3.5mm AUX jack is fully inserted.
- Poor Audio Quality/Interference: Move your phone closer to the adapter to ensure it's within the 10-20m transmission range. Avoid placing the adapter near strong electromagnetic interference sources.
- Call Quality Issues: The microphone is located on the USB end of the adapter. If the USB end is hidden (e.g., in an armrest box), it might affect call quality. Try to position the USB end closer to you for better voice pickup.
- Adapter Emits Sounds: The adapter is designed to emit a sound when it connects or disconnects from a Bluetooth device, confirming its operational status. This is normal behavior.
8. User Tips
- Optimal Microphone Placement: For the best hands-free call quality, ensure the USB end of the adapter, where the microphone is located, is not obstructed and is as close to you as possible. Avoid placing it deep inside compartments like armrest boxes.
- Connection Confirmation: Listen for the audible tone from the adapter when it connects to your device. This confirms a successful Bluetooth link.
- Auto-Reconnection: Take advantage of the auto-reconnection feature. Once paired, the adapter will automatically link with your phone when it's powered on (e.g., when you start your car), saving you the hassle of manual connection each time.
