Let’s start with a physical tour of the Hitachi RS-55 projector.
The front of the projector sports a lens that is recessed for protection. The projector’s lens has a fixed throw – that is, no zoom capability. There is also an IR sensor, and below, two adjustable feet.
Moving to the top from the front, is the focus dial, and behind it 3 indicator lights (lamp, temperature and power), and below it the control panel, consisting of an input button, and an all purpose disk. Pressing the disk in the center opens the menu, and when needed pressing it again, with the menus open, it functions as the enter key. The four arrow keys are marked on the disk and when you press to the appropriate side, it moves you through the menus and adjustments. Lastly, at the bottom of the control panel, is the power switch.
