    <p>Some models of soundbars use colored LED lamps to indicate the status of external inputs or connections.<br/>
      You can check the status of the soundbar by observing the color of the LED lamps.<br/>
      The lamp colors may vary
      depending on the soundbar model. For detailed information, please refer to the user
      manual of your specific model.</p>
