How to open the hotel do not disturb mode?

Just turn on the light in scrambling mode.

The hotel do not disturb light is turned on in the center console or at the door of the hotel room, so the staff will not knock after it is turned on.

When the floor attendant cleans the room at ordinary times, when he sees a "Do Not Disturb" sign or a "Do Not Disturb" light on the door, he should make a note on the work list.
