Volume operation (Only for countries/areas complying with European Directives)
An alarm (beep) and a warning [Check the volume level] are 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.
The alarm (beep) does not sound when connected to a Bluetooth audio device.
