Adjusting the Lens
Using the Lens Shift
Adjust the lens using the focus and zoom 
rings to correct the image.
1Adjust zoom by rotating the zoom 
ring.
2Adjust focus by moving the focus 
ring.
The height and width of the projected image 
can be adjusted to be within the shift range of 
the lens by rotating the lens shift dial at the top 
of the projector.
 Note
•Do not forcibly turn the lens shift dial beyond 
the range of the upper left and lower right 
positions. This may cause the projector to 
malfunction.

Connections and Setup
Setting up the Screen
Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Standard Setup (Front Projection)
„Place the projector at the required distance from the screen 
according to the desired picture size. (See page 23)
An Example of Standard Setup
 Notes
•The projector lens should be perpendicular (square-on) to the screen. If the horizontal line passing 
through the lens center is not perpendicular to the screen, the image will be distorted, making viewing 
difficult. 
•For an optimal image, position the screen so that it is not in direct sunlight or room light. Light falling 
directly on the screen washes out the colors, making viewing difficult. Close curtains and dim the lights 
when setting up the screen in a sunny or bright room.
•A polarizing screen cannot be used with this projector.
•The distance from the screen to the projector 
depends on the size of the screen.
•The default setting can be used, when placing the 
projector in front of the screen. If the projected 
image is reversed or inverted, readjust the setting to 
“Front” for “PRJ Mode” in the “Options” menu.
•Place the projector so that an imaginary horizontal 
line that passes through the center of the lens is 
perpendicular to the screen.
 Notes
2D Lens Shift:
•The vertical display (Biggest) is (+13/20V / - 
1/2V) screen. 
•The horizontal display (Biggest) is ±3/40 
screen. (±15%)
•It is recommended that images be projected 
onto the dashed line octagonal area for fine 
image quality.
•There is a tolerance of ±3% in the formula 
above.
