Each projector is equipped with adjustable focus to ensure a sharp image. There are 3 variants: manual focus which can be adjusted by hand via the focus wheel, the powered focus adjustable by pressing a button. Advantage of the powered focus is that when the projector is installed to the ceiling, it can be operated by remote control. There is also the auto focus which automatically adjusts the focus via an internal sensor.
