From the front of the InFocus IN83 projector: The manual zoom lens has a 1.2:1 zoom ratio, which is typical of DLP projectors, and far less range than any of the 3LCD or LCoS competitors. The lens is mounted off-center, to the left. For a 100" diagonal screen, the front of this InFocus IN83 projector can be as close as 13.5 feet, and as far back as 16.1 feet. Lens offset will be discussed in the General Performance section.
That's all that's going on at the front of this InFocus projector.
There are no adjustable feet, of course, because of the provided InFocus swivel (and tilt) base (not shown). The smaller InFocus home theater projectors come with the base attached, right out of the box. As I said, though, most will mount this projector so InFocus packed them separately.
On the top of the projector, or rather on the front left edge, at the top (if looking from behind), is the only infra-red sensor. From using the projector in both my theater and testing room, that one is all that is needed. It is essentially invisible on the projector itself.
On the opposite side, the front right, if looking from the back, is a removable door that lets you access large zoom and focus wheels for the zoom lens.
On the top of the projector, centered, right at the back, is a black Indicator panel, that when the projector is unplugged, is essentially invisible. However, on that panel are indicator lights for Power, Temperature, Lamp, and Service.
Immediately below is the input panel of the InFocus IN83. Once again, since the IN83 will be ceiling mounted in most installations, all the labeling is upside down to make the labels easier to read when the projector is mounted and it is time to connect cabling. For your convenience, I have flipped (vertically) the image of the input panel to make it more readable.
