Adjustable Feet
Located on the underside of the projector are four adjustable feet. Raise or lower these feet when positioning
the projector to ensure it is level on all sides so the displayed image will appear rectangular without any
keystone. See 2.4.7 Adjusting Projector Height/Tilt
Input Panel
All source connections are made to the input panel located at the back of the projector. Any of the available
optional input cards can be installed in the 4 option card slots. The slots are labelled 1 through 4. All option
cards have LEDs to indicate their status.
Cooling and Air Vents
There are numerous air vents located around the projector. It is important these vents remain unobstructed.

The two IR sensors located on the projector receive transmissions from the IR remote from up to 100 feet

tions with the projector. The rear IR sensor is located at the back of the projector between the status LEDs and
the front IR sensor is located next to the projector front nameplate.

horizontal offsets, zoom and focus.
• Zoom and Focus: There are two internal lens motors that allow for quick motorized adjustment of zoom and
focus. Adjust zoom to fit the displayed image on the screen and adjust focus to improve the clarity of the
image.
