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 11.) 

•  Do not place this projector on a carpet or blanket because the exhaust vent and the intake vent on the bottom 

surface are blocked and the inside of the projector is heated, causing a breakdown or fi re. 

•  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 three feet for 
adjusting the projection angle on the bottom 
surface. Adjust the projection angle depending on 
the position of the projector. 

Adjustment of the projection angle
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 two 
adjustment feet on the bottom of the projector. 

1.  Tilt up the projector to the appropriate angle. 
2.  Press the foot adjustment buttons next to the 

adjustment feet (rear), and the adjustment feet 
will come out. 

3.  Release the buttons to lock the adjustment feet 

(rear) to that position.

4.  Rotate the adjustment feet (rear) for fi ne 

adjustment.

After using the projector:
5.  Put the adjustment feet (rear) back into the 

projector by pressing the foot adjustment 
buttons.

•  If necessary, rotate the adjustment feet (front) for 

fi ne adjustment. 

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 16.) 
•  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. 

•  The setting value displayed at the time of the 

keystone adjustment may vary depending on the 
type of the input signal. 

•  The keystone mode does not function when the 

REAL mode is applied.
