The projector is built with a motorized lens mount that allows for easy lens control
and adjustment. This includes such functions as adjusting vertical and horizontal
offsets, zoom and focus. The lens mount can be fitted with any one of the available
optional lenses – see
Section 6 - Specifications
.
•
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.
NOTE: You can manually override zoom and focus adjustments set with the
remote. Turn the outer ring on the projection lens to adjust focus and the inner
ring to adjust zoom.
•
Lens Offset
– Vertical and horizontal offset is performed on the lens mount
through the use of DC motors.
•
Shutter
– Standard on all models the shutter allows you to turn the screen
absolutely black when in the “on” state.
•
Optical Aperture
– Enables adjustment of light output and contrast ratio.
NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the
lens cap when transporting the projector to avoid scratching and damaging the lens,
which could affect your displayed image.
All source connections are made to the input panel located at the back of the projector.
Connect RGB or YPbPr sources to
INPUT 1
, analog or digital display signals to
INPUT
2
, composite video to
INPUT 3
, and S-video to
INPUT 4
. Any of the available optional
modules can be installed in
INPUT 5
and/or
INPUT 6.
There is no status display on the input panel. The only status display is part of the
built-in keypad located at the rear of the projector.
There are numerous air vents located around the projector. It is important these vents
remain unobstructed. Adequate airflow through the projector will prevent it from
overheating.
The two IR sensors located on the projector receive transmissions from the IR remote
from up to 100 feet away. It is important to keep the transmission path to these sensors
unobstructed for uninterrupted communications with the projector. The front IR
sensor is located next to the projector’s nameplate and the rear IR sensor is located at
the back of the projector just above the status LED display.
The lamp door is located at the back of the projector, which provides easy access to
the lamp module for replacement. See
Section 4
for lamp replacement procedures.
