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 3 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 2 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 foot (front) for 

fi ne adjustment. 

•  To correct vertical and horizontal keystone distor-

tion, press the KEYSTONE button on the projector 
or the remote control to display KEYSTONE, and 
adjust the image by pressing the 

, ,  or  

button (or VOLUME + or - button on the remote 
control). 

•  You can correct the vertical and horizontal key-

stones at the same time. However, their adjust-
ment ranges are limited in such correction. 

•  When the keystone adjustment is carried out, the 

adjustment value is indicated.  Note that this value 
doesn't mean a projection angle. 

•  The allowable range of the adjustment value in 

the keystone adjustment varies depending on the 
installation conditions. 

•  When the keystone adjustment takes effect, the 

resolution decreases. In addition, stripes may 
appear or straight lines may bend in images with 
complicated patterns. They are not due to product 
malfunctions.  

•  Noise may appear on the screen during the key-

stone adjustment because of the type of the video 
signal being projected and the setting values of 
the keystone adjustment. In such cases, set the 
keystone adjustment values in the range where 
the image is displayed without noise. 

•  When the keystone adjustment is carried out, the 

image may not be displayed correctly because of 
the type of input signal.

•  Displayed image may be distorted during keystone 

adjustment.
