The first quarter turn, rotates the tab outwards, and the following turns tighten the tabs to the rear side of the ceiling surface

When tightening the mounting tabs, the tabs automatically turn outward, thus clamping the speaker to the wall from its rear side.

Note: Do not over-tighten the screws. It may cause damage to both the speakers and the surface.
