A new card on the kitchen screen makes a two-note sound on this device, because a cook facing the grill is not facing the screen. A rush ticket rings longer. The first load of the night is silent, and a recalled ticket does not ring twice.
A manager turns it off under ⚙ → This terminal → Kitchen chime with On · Off; tapping On plays it once so you hear what it is. The dashboard can push the setting to a device.
