Notes on the volume for calls on smartphones
The volume for music and the volume for calls are independent of each other. You can adjust the volume for calls while you are talking on the phone. When you hang up the call, the volume returns to the level for music.
If the AVLS function is active, the player will keep the volume for calls at a moderate level.
