4. Maintenance and Care
To ensure the longevity and optimal performance of your Aune ARU1 cable, follow these simple care guidelines:
- Handling: Always grasp the connectors when plugging or unplugging the cable. Avoid pulling directly on the cable itself, as this can damage internal wiring.
- Cleaning: Use a soft, dry, lint-free cloth to clean the cable and connectors. Do not use liquid cleaners or abrasive materials.
- Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling or bending the cable sharply, which can stress the internal conductors.
- Moisture: Keep the device away from water and high humidity. If the cable gets wet, disconnect it immediately and allow it to dry completely before re-using.
5. Troubleshooting
If you encounter issues with your Aune ARU1, please refer to the following common troubleshooting steps:
- No Sound Output:
- Ensure the ARU1 is securely connected to both your headphones and the source device.
- Check your source device's volume level and ensure it is not muted.
- Verify that the ARU1 is selected as the default audio output device in your computer's or smartphone's sound settings.
- Test with another pair of headphones or another source device to isolate the problem.
- Poor Sound Quality / Distortion:
- Ensure the audio source file or streaming quality is high. Low-quality audio sources will not be improved by the ARU1.
- Check for any loose connections.
- Try restarting your source device.
- Ensure there are no other audio processing applications or drivers interfering with the ARU1's operation.
- Device Not Recognizing ARU1:
