Selecting an Image Source While Viewing Projected Images (Preview Function)
The preview function lets you project the images from the currently-
selected image source and view them in a preview screen while selecting 
the signal source.
Use the remote control to carry out all preview function operations.PROCEDURE
Press the [Preview] button on the remote control.
After a short while, a preview screen such as the one shown in 
the illustration below will appear on the screen.
When the preview screen is being displayed, the frames for 
ports that have no image signal being input or which have a 
signal being input that is not supported will be solid blue.
Press the [Source] buttons on the remote control to select the 
image source to be projected in order to change the image.
TIP
• If only one signal source has been connected, the signals from that 
source will be projected without needing to press one of the [Source] 
buttons.
 If the No Signal. message does not disappear, check the 
connections again.
 If a laptop computer or a computer with an LCD screen has been 
connected to the projector, the images may not be projected straight 
away. After starting projection, check that the computer has been set 
up to output signals externally. 
The following table shows examples of how to toggle output settings. 
For details, refer to the section of the documentation provided with 
your computer under a heading such as External output, 
Connecting an external monitor or similar.
 If the same still picture is projected for a long period of time, the 
projected image may become burned in on the computer screen. You 
should avoid leaving the same image displayed for long periods.

Adjusting the Screen ImageYou can correct and adjust the screen images in order to obtain the best 
possible pictures.Adjusting the Image Size (Zoom Function)
The size of the projected images is basically determined by the distance 
from the projector to the screen.   p.16
The following procedures explain how to adjust the screen images once the 
projector itself has been set up.PROCEDURETurn the zoom ring on the projector to adjust the image.
If a Wide Zoom Lens is fitted, the image can be enlarged in this way 
to 1.35 times the normal size.
If you would like to enlarge the images further, move the projector 
further away from the screen.   
p.16
Focusing the Screen Images (Focus Adjustment)
PROCEDURETurn the focus ring to adjust the image focus.
If keystone correction or Sharpness settings have been made, it may 
not be possible to adjust the focus correctly.
TIP
The E-Zoom function can also be used to enlarge parts of the images.   p.59
Turn to W to 
increase the size
Zoom ring Turn to T to 
reduce the size
Focus ring
TIP
• If the surface of the lens is dirty or misted over as a result of 
condensation, it may not be possible to adjust the focus correctly. If 
this happens, clean or de-mist the lens.    p.116, p.123
 If using the Wide Zoom Lens and the projector is positioned outside the  normal projecting range of 77–1113 cm (2.5–36.5 ft.), it may not be 
possible to obtain the correct focus. If you have trouble obtaining the 
correct focus, check the projection distance. If an optional lens is fitted, 
refer to the documentation for the optional lens for further details. 
						

							38
Adjusting the Screen Image
Adjusting the Image Angle
If the projector is set up so that it is at a horizontal or vertical angle to the 
screen, adjust as follows.
If the images are being projected onto a screen that is higher than the 
position of the projector, extend the front adjustable foot to tilt the 
projector.  p.39
Tilting the projector may cause a keystone distortion to the image, but the 
automatic keystone correction function will automatically corrects the 
image distortion.   p.41If the projector cannot be set up directly in front of the screen, you can 
project images at a horizontal angle to the screen. If keystone distortion 
appears in the images, you can use the projectors H-Keystone and 
Quick Corner functions to correct this keystone distortion.   p.42, p.44Tilting the projector vertically with respect to the screen
CAUTION
The maximum downward tilt angle is when the rear adjustable foot is 
extended to its limit. Do not tilt the projector downward any further 
than extending the foot.
When projecting from the side of the screen 
						

							39
Adjusting the Screen Image
The front adjustable foot and the rear adjustable feet can be extended and 
retracted to adjust the tilt of the projector to a maximum of 12º upward and 
4º downward.PROCEDUREWhile pulling the foot adjust lever at the front of the 
projector, lift up the front of the projector to extend the 
front adjustable foot.
Extend the front adjustable foot until the desired angle is obtained, 
and then release the foot adjust lever.
To retract the front adjustable foot, gently push down on the projector 
while pulling the foot adjust lever. Adjusting the Feets
TIP
If you use the front adjustable foot and the rear adjustable feet to 
adjust the tilt of the projector, it may cause keystone distortion to 
appear in the projected images. If this happens, the Auto Keystone 
function will operate to automatically project images without keystone 
distortion. 
  
p.40
Foot adjust lever (Front)
TIP
If the projector is tilted vertically or horizontally, turn the bases of the 
rear adjustable feet to make fine adjustments to the height of the 
projector. When the projector is tilted horizontally, the correction may 
not be carried out correctly.
