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 or tap either of the tap sensors to cancel the alarm and
warning.
Note
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 player after you have selected a high volume that may damage your eardrums, the volume level will
automatically be lower when you turn on the player the next time.
The alarm does not sound when the player is in the Headphone Mode.
