Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the 
projection angle of the projector. (See below.)
•  Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of 

the screen center. 

•  Do not install the screen where it is exposed to direct sunlight or lighting. Light directly refl ecting on the screen 

makes the projected images whitish and hard to view. 

Determine the distance from the screen to the projector according to the size of the images to be projected. (See 
page 12.) 

•  Depending on the installation conditions, warm air that is emitted from the exhaust vents may fl ow into the intake 

vent, causing the projector to display “TEMPERATURE!!” and then stop projecting images. 

This projector is provided with 2 feet for adjusting 
the projection angle on the bottom surface. Adjust 
the projection angle depending on the position of 
the projector. 

Adjustment of the vertical position of the 
projector
For the best projection, project images on a fl at 
screen installed at 90 degrees to the fl oor. If 
necessary, tilt the projector using the adjustment 
foot (for the vertical position) on the bottom of the 
projector. 

1.  Tilt up the projector to the appropriate angle. 
2.  Rotate the adjustment foot (for the vertical 

position) for fi ne adjustment.

After using the projector:
3.  Put the adjustment foot (for the vertical position) 

back into the projector.

Adjustment of the horizontal position of the 
projector
Adjust the horizontal position of the projector with 
the adjustment foot (for the horizontal position) on 
the bottom.

Screen

When projected images are distorted to a 
trapezoid:
When the screen and the projector are not placed 
perpendicularly to each other, projected images 
become trapezoidal. If you cannot make the 
projector and the screen perpendicular to each 
other by mechanical adjustments, adjust keystone. 
(See page 21.) 
•  When the keystone adjustment is applied, the 

correct aspect ratio may not be obtained. 

•  When the keystone adjustment is applied, the 

resolution lowers. In addition, vertical stripes ap-
pear and straight lines bend in images with com-
plicated patterns. To prevent such symptoms, 
keep the screen and the projector perpendicular 
to each other as much as possible. 

•  Though the projected image may be distorted 

momentarily when you change the setting value 
of the keystone adjustment, such symptom is not 
a malfunction. 

•  Though the projected image may be distorted 

depending on the setting value of the keystone 
adjustment and the type of the input signal, such 
symptom is not a malfunction. In such a case, 
adjust the setting value within the range where 
the projected image is not distorted. 

This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace the focus 
a little. (See page 15 or 19 for focus adjustment.)
