Volume operation in compliance with European and Korean Directives

  • For European customers
  • For Korean customers

The voice guidance “Check the volume level” is intended to protect your ears. You will hear this voice guidance initially after you turn up the volume to a harmful level. Press any button to cancel the alarm and warning.


  • You can turn up the volume after you cancel the alarm and warning.
  • After the initial warning, the alarm and warning will repeat every 20 cumulative hours that the volume is set to a level that is harmful to your ears. When this happens, the volume will turn down automatically.
  • If you turn off the Walkman after you have selected a high volume that may damage your eardrums, the volume level will automatically be lower when you turn on the Walkman the next time.
  • The alarm does not sound when the Walkman is in the Headphone mode.
