y Position the projector on a flat surface at a right angle to the screen. The 
projector (with the standard lens) must be at least 3 feet (0.9m) fr\
om the 
projection screen.
 
y Position the projector to the desired distance from the screen. The 
distance from the lens of the projector to the screen, the zoom setting,\
 and 
the video format determine the size of the projected image.
 
y For the fixed short lens, the image exits at a default angle. However, the 
lens shift feature makes the image offset variable.
 
y Lens throw ratio:
 
-
Lens 1.22~1.53 (WU/HD)
 
-
Lens 0.95~1.22 (WU/HD)
 
-
Lens 1.52~2.92 (WU/HD)
 
-
Lens 1.28-1.61 (WX)
 
-
Lens 1.0-1.28 (WX)
 
-
Lens 1.6-3.07 (WX)
 
y Do not roll the projector more than 20 degrees from side to side.
 
y Do not put the projector on either side to project an image.
3.5  Adjust the Projector Position
When you select a position for the projector, consider the size and shap\
e of 
your screen, the location of your power outlets, and the distance betwee\
n the 
projector and the rest of your equipment. Follow these general guideline\
s:
360°

y The vertical image offset (shift) ranges for the projector are +/-100%\
 
(WXGA/WUXGA) and +/-120% (HD). The horizontal image offset (shift)\
 
range for the projector are +/-20% (WXGA/HD/WUXGA). 
 
y The method for calculating lens offset complies with Industry standards.\
 
Example for Vertical lens offset:
 
-
At 0% offset (or on axis), the center of the image is on the lens cent\
er, 
so that half of the image appears above and half appears below the 
lens center.
 
-
At +100% offset, all (or 100%) of the image will appear above the lens\
 
center.
 
-
The % offset is calculated as the ratio of the number of pixels shifted \
up/down to half the image size. Examples for WUXGA:
 
`Shifting up 600 pixels gives offset of 600/600 * 100% = 100%
 
`Shifting down 600 pixels gives offset of -600/600 * 100% = -100%
 
`Shifting up 720 pixels gives offset of 720/600 * 100% = 120%
 
`Shifting up 240 pixels gives offset of 240/600 * 100% = 40%
WUXGA Projectors:
Vertical Image Offset: 0% Offset (WUXGA)
No offset is applied - 0% offset.
Half of the image appears above lens center 
and half of the image appears below lens 
center.

3.7  Removing and Installing the Lens
When handling the projector after lens installation, make sure the front\
 lens cap is 
placed on the lens to protect the lens surface from potential damage. Wh\
en carrying 
or moving the projector, do not handle by the lens. This may damage the \
lens, the 
chassis or other mechanical parts within the projector.
1. Center the lens: Ensure that the lens is at or near its center position. Attempting to 
remove the lens when at a large offset may cause damage to the lens asse\
mbly. Center 
the lens while the projector is switched on by pressing the lens horizon\
tal or vertical 
button and then pressing Enter.
2.  Turn Off the projector:  Turn the projector OFF.
3.  Wait for projector to cool down:  Allow the projector to cool down into standby mode 
before replacing the lens. Remove power cord after the projector has coo\
led down and 
prior to replacing the lens.
4.  Remove the lens: Remove the lens ring cover.  Rotate the lens counter-clockwise by a quarter to release the lock. Remo\
ve the lens 
through the front of the projector.
Installation Steps:
5.  Install the new lens:  Fully insert the lens assembly straight into the lens mount without 
turning. Rotate the lens cap clockwise to lock the lens in place.
