Projection on the screen (continued)
(Signal sent from the computer)• If you project an image from a computer with an LCD screen while monitoring the image on
the computer, the image may not be projected properly, depending on the computer model.
In this case, turn off the computer display.  For details on controlling the computer display,
etc., refer to the computers manual and description on the software for the computer used.
• The projector projects an image by XGA signal (1024 x 768) in full screen.
• The image quality of a computer signal except XGA may deteriorate.  It is recommended to
set the external monitor connected to the computer to XGA mode (1024 x 768).
• The projector can be also applied to DDC2B (Display Data Channel 2B).  If your computer is
applied to the DDC, start up your computer after turning on the projector.
Adjust the picture size by turning the
zooming lever.Turn to the right to enlarge the picture.
Turn to the left to reduce the picture.Focus on the picture by turning the
focusing ring.A still picture is recommended for focusing.

• When the screen image is distorted in keystone, press the KEYSTONE button to adjust the
distortion.
• Due to the lamp characteristic, flickers may occasionally occur in a picture. This is not
malfunction of the unit.
• The lamp may rarely burst with a big sound.
• The projectors liquid crystal panel is made using extremely advanced technology, but there
may be black spots (pixels that do not light) or bright spots (pixels that are constantly lit) on
the panel. Please note that these are not malfunctions.
• When trying to press the button whose operation is not available, the icon          appears.
• When supplying the signal not compatible to the projector, the icon        appears.
• When signals are not input from the input source, the icon        appears.
• The projector may stop operating if the surrounding temperature is too high or if the air filter
is clogged with dust.

Turning the power off
Press ON/STANDBY after using the projector.An instruction message for turning the power off appears on
the screen and disappears after a while.  When the
message disappears, operation becomes invalid.Press ON/STANDBY again.Cooling starts. Once cooling is completed, the LAMP and
FAN indicators turn off and the standby mode is set. (The ON
indicator turns in orange.)
To protect the light source lamp, the LAMP indicator blinks as long as a mini-
mum of cooling is necessary. The power cannot be turned back on during this
time. Unplugging the power cord at this time will shorten the lamps duration life.
The cooling fan continues to run for a while to expel the heat remaining inside.
If you are in a hurry, however, you may unplug the power cord at this time.The standby mode is set.
• The projector consumes about 20W of power in the standby mode. We recommend you to
unplug the power cord when not using the projector for long periods of time.
• Be sure that the LAMP indicator has turned off before unplugging the power cord.  Cutting
the power by unplugging the power cord while the projector is operating or the light
source lamp is being cooled will shorten the lamps duration life. Should a fault or some
other irregularity arise with this unit, unplug the power cord.
• When reinserting the power plug before the lamp has cooled, please wait until the lamp has
cooled sufficiently before use. When the lamp is at a high temperature, it may not light and
the duration life will be shortened. Remote control

Adjusting the picture automatically
You can adjust the optimum horizontal position, vertical position, sampling phase
and sampling frequency for projecting analog RGB signals at the touch of a button.
Input full screen video signals from the input
source (computer) and project the image.Adjustments may not be performed properly for images that
are not displayed on the entire screen or extremely dark
images.Press AUTO SET.The horizontal position, vertical position, sampling phase and
sampling frequency are adjusted automatically.
The icon         appears during signal processing.
• Automatic adjustment may not be performed properly for signals other than the computer’s
signals with which the projector is compatible.
• The horizontal position, vertical position, sampling phase and sampling frequency can also
be adjusted from the menu screen.
* Sampling frequency
Analog RGB signals input from the computer are converted into digital signals inside the
projector.  The sampling frequency is the number of times per second the analog signals
are converted into digital signals.  In order to capture (sample) each individual dot of the
computer’s signals, the sampling frequency must be adjusted to match the computers dot
clock frequency. If this adjustment is off, details of the image may be blurred, a striped
pattern may appear when images with many vertical lines are displayed, or the images
width may change. For computer’s signals with which the projector is compatible, the
sampling frequency is adjusted automatically even without pressing the AUTO SET
button.
* Sampling phase
The sampling phase is the timing at which the computers analog RGB signals are sampled.
If the sampling phase is off, the individual dots cannot be sampled at the proper timing,
resulting in blurred or flickering images. Remote control

Due to digital correction processing, some of the information may dropped or the picture quality may
be degraded depending on the keystone correction setting or the contents of the signal source.•The adjustable range of V-keystone or H-keystone is influenced by the quantity of correction
of each other.• When Auto. V-keystone does not operate properly even with the screen installed vertically,

• Enlarged images can be frozen by pressing the FREEZE button. The images frozen also
can be enlarged or reduced.
•
The resize mode is cancelled if any operation other than setting the freeze mode is performed.• This projector uses electrical digital resizing, so the picture quality degrades when images
are enlarged.

• With some signals, the image cannot be enlarged.
• This function does not work in no input status (no signal is supplied from the signal source).
The enlarged section is moved when the selection buttons
(                      ) are pressed.  The section can be moved
continuously by keeping the button pressed in. To reduce the enlargement ratio, press the RESIZE (     )
button.  The enlargement ratio can be reduced continuously
by keeping the button pressed in.Press RESIZE (     ).The enlargement ratio increases each time the RESIZE (     )
button is pressed.  The enlargement ratio can be increased
continuously by keeping the button pressed in.
