The front switch controls the entire circuit part. When the music box is shaken, the light will gradually light up. When the music box stops shaking, the light will gradually go out.

Notice: Turn off the main switch when not shaking, because the built-in circuit part will consume power even if the light is not on.

The music box part can be played continuously for 1 minute and 30 seconds at normal speed. (Changes depending on the hand-cranking speed) and automatically rolls back to loop playback.
