They have announcements, specific to changes. Otherwise, they automatically announce that the belt will begin to move, produces buzzer warning and then moves. What additional info do you need?
Just posts above the baggage claim area belt. The only announcement is that the belt is about to start to stsnd back. The baggage belt for your flight is slso posted on the display as you are coming down the escalator to the baggage area and also on the flight boards in the hallways on the first floor.
