The voice guidance “Check the volume level” is meant to protect your ears when you turn the volume up to a level that is harmful for your ears for the first time. You can cancel the alarm and warning by pressing any button.

Note

• You can turn up the volume after canceling the alarm and warning.
• After the initial warning, the alarm and warning repeat every 20 cumulative hours that the volume is set to a level that is harmful for your ears. When this happens, the volume is turned down automatically.
• If the volume is set to a level that is harmful for your ears and you turn off your Walkman, the volume is turned down to a level that is safe for your ears automatically.
