4If more than one signal source has 
been connected, use the 
projector
s control panel or the 
remote control buttons to select the 
port which the signal source that 
you would like to use is connected 
to, while referring to the following 
table.
* The items selected using the Input Signal command in the Video menu 
will appear.
Tip :
 If only one signal source has been connected, the signals from that source will be 
projected without needing to press one of the buttons from the previous table.
 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 making the 
connections, 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.Po r tButton to press

Adjusting the Screen Image
You can correct and adjust the screen image in order to obtain the best possible 
picture.
Adjusting the Image Size
The size of the projected image is basically determined by the distance from the 
projector to the screen. (p.16)
If further minor adjustment is required, press the [Zoom] button on the 
projectors control panel to make the adjustment. Minor adjustments can be 
made to the image size to between a zoom ratio of approximately 1.0 to 1.2 in 
33 steps.
Tip :
The E-Zoom function lets you enlarge parts of the image. (p.45)
Procedure
Press the [Zoom] button on the projectors control panel.
When pressed to the [W] side, the images become larger.
When pressed to the [T] side, the images become smaller.

Adjusting the Image Angle
The projector should be set up so that it is as perpendicular to the screen as 
possible.
If it is not possible to set up the projector so that it is perpendicular to the 
screen, it can be set up at a slight vertical angle instead. You can extend or 
retract the front adjustable feet to adjust the projection angle within a maximum 
range of 10º.
Procedure
While pressing the two foot adjust 
buttons at either side, lift up the front 
of the projector so that the front 
adjustable feet can extend.
Extend the front adjustable feet until the 
desired angle is obtained, and then release the 
foot adjust buttons. 
To retract the front adjustable feet, gently push 
down on the projector while pressing the two 
foot adjust buttons.
Tip :
 When the foot is adjusted, it may cause the projected images to become distorted. Use 
the keystone correction function to adjust this distortion. (p.35)

 If the projector is tilted horizontally, turn the bases of the front adjustable feet to adjust 
the angle.
Correcting Keystone Distortion
When the projector is tilted, it will cause keystone distortion to appear in the 
image, but this distortion can be corrected using the keystone correction 
function as long as the vertical angle of tilt is within a range of approximately 
15º.

Procedure
Keystone correction can be carried out using either the projectors control panel 
or the configuration menu. The following explanation describes how to correct 
keystone distortion using the projectors control panel.
For adjustment using the configuration menu: Setting - Keystone (p.51)
Tip :
 When keystone correction is carried out, the projected image will become smaller.
 The keystone correction settings are memorised even when the power is turned off. If 
you change the position or angle of the projector, you may need to readjust the keystone 
settings.
 If the images become uneven in appearance after keystone correction is carried out, 
decrease the sharpness setting. (p.47, 48)
 If the value displayed in the gauge on the screen stops changing when keystone 
correction is being carried out, it indicates that the limit for keystone correction has 
been exceeded. Check that the projector has not been set up at an angle which exceeds 
the proper limit.

Adjusting the Image Quality
The quality of the screen images can be adjusted as follows.
Focusing the Screen Image
Procedure
Turn the focus ring to adjust the image 
focus.
Turn the focus ring of the projector until the 
projected images are in proper focus.
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.66, 72)
 If the projector is positioned outside the normal projecting range of 0.9–11.3 m (2.9–
37.0 ft.), it may not be possible to obtain the correct focus. If you have trouble 
obtaining the correct focus, check the projection distance.
Adjusting Computer Images
Automatic setup detects the status of the signals coming from the connected 
computer, and automatically adjusts these signals so that the optimum images 
can be obtained. It involves adjustment of the following three items:
Tracking
, Position and Sync.
Tip :
 If Auto Setup in the Video menu is set to OFF (the default setting for this item is 
ON), automatic setup is not carried out. If you press the [Auto] button on the remote 
control while computer signals are being projected, adjustment will then be carried 
out.

							38  If you press the [Auto] button while the E-Zoom or Freeze function is being used or 
while a configuration menu or help menu is being displayed, the function will be 
cancelled when you press the [Auto] button, and then the adjustment will be carried 
out.
 Sometimes the signals may not be adjusted correctly depending on the type of signals 
being output by the computer. In such cases, use the configuration menu commands to 
adjust the tracking and sync settings manually. (p.38, 39)
If vertical stripes appear in the projected 
images, and this cannot be fixed using 
automatic setup, you will need to adjust the 
tracking
 manually using the following 
procedure.
Procedure
1Press the [Menu] button on the 
remote control, and then select 
Tracking from the Video 
menu.
For details on this operation, refer to 
Using the Configuration Menus. 
(p.56)
2Press the [ ] and [ ] buttons 
to set the tracking value.
The tracking value increases or 
decreases each time a button is 
pressed.
3After making the adjustment, press the [Menu] button to exit 
the configuration menu.
Tip :
The image will flash when continuous tracking adjustment is carried out, but this is 
normal.
