[TW Series] Why doesn't the volume increase after two high-pitched sounds?
Last Update: 24-9-2020
The high-pitched sound is a notification that the volume is at MAX.
When you hear the notification tone, you cannot increase the volume any further.
With the TW-E7A, you will hear the notification tone when the volume is at MIN too.
