Setting up your projector (continued)
Adjusting the position of the projected image
To adjust the positions of the projector and the screen, use LENS SHIFT button.
1. Press the LENS SHIFT button.
• The LENS SHIFT menu appears at the center of the screen.
2. Press the S, T, W or X button to move the image position.
• When the T button is pressed, the image moves down.
• When the
S button is pressed, the image moves up.
• When the X button is pressed, the image moves to the right.
• When the W button is pressed, the image moves to the left.
• When the ENTER button is pressed while the LENS SHIFT menu is displayed, the shift mode can be switched
between FAST and STEP. When FAST is selected, the lens shifts in a large amount with the S, T, W or X button,
and it shifts in a small amount when STEP is selected.
• When the LENS SHIFT menu is displayed while no video signal is input to the projector, a crosshatch appears on
the entire screen.
• Be careful not to be caught in the opening in the lens while the lens is moving.
• While the lens shift is working, the screen may fl icker.
Correcting skewed or distorted image
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. Rotate the adjustment feet for fi ne adjustment.
Important:
• Don’t transport the projector with its adjustment feet extended. Otherwise the
adjustment feet may be damaged.
When fi ne streaks are seen on projected images
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 16 or 22 for focus 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.
To adjust keystone:
Press the KEYSTONE button on the projector or the
remote control to display KEYSTONE, and adjust the
image by pressing the X, W, S or T button (or VOLUME
+ or - button on the remote control).

Important:
• For proper keystone adjustment results, reset the lens to the factory-adjusted position using LENS SHIFT RESET
in the INSTALLATION menu before carrying out keystone adjustment. (See page 30.)
• 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.
• When the keystone adjustment is performed, the displayed image may be distorted.
• Depending on the installation conditions of the projector and the screen, a perfect rectangular image and the
proper aspect ratio may not be obtained.
• Noise may appear on the screen during the keystone 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 horizontal and vertical keystone adjustments are performed in combination, the adjustable range becomes
narrower than in the case when they are performed separately.
• In the keystone adjustment with the option lens, the proper aspect ratio may not be obtained.
