the projectors control panel or the 
remote control to turn on the power 
for the projector.
The Power indicator flashes green, and 
after a short period it stop flashing and 
projection starts.
Check that the Power indicator stops 
flashing and lights green (it normally 
takes about 40 seconds to change).

4If more than one signal source has 
been connected, use 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 a 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.
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

Turning Off the Projector
Follow the procedure below to turn off the power of the projector.
Procedure
1Turn off the power for the signal sources that are connected to 
the projector.
Check that the power for all connected components has been turned off.
2Press the [Power] button on either 
the projectors control panel or the 
remote control.
The following confirmation message will 
appear.
If you do not want to turn off the power, press any button except the

If you do not press any button, the message will disappear automatically 
after seven seconds. (The power will not turn off at this time.)
3Press the [Power] button once 
more.
The lamp will switch off. The Power 
indicator will flash orange and cool-
down will start.
4Check that the cool-down is 
complete.
When cool-down is complete, the Power 
indicator lights orange.
The cool-down period lasts about 30 - 45 
seconds. (This varies depending on factors 
such as the ambient air temperature.)
Tip :
The projector’s control panel and remote control buttons cannot be operated while the 
Power indicator is flashing orange. Wait until it lights steadily.

5Unplug the power cord from the 
electrical outlet.
Caution :
Do not disconnect the power cord from the outlet while the Power indicator is still 
flashing orange. If you disconnect the power cord while the indicator is still flashing, it 
may result in errors in projector operation and reduce the lamp unit operating life.
6Retract the front adjustable feet if 
they are extended.
Gently push down on the projector while 
pressing the two foot adjust buttons.
7Attach the lens cover.
Attach the lens cover to the lens when not 
using the projector, in order to stop the 
lens from getting dusty or dirty.

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.15)
The following procedures explain how to adjust the screen image once the 
projector itself has been set up.
Tip :
The E-Zoom function lets you enlarge parts of the image. (p.47)
Procedure
Turn the zoom ring on the projector to 
adjust the image.
The image can be enlarged in this way to 1.16 
times the normal size.
If you would like to enlarge the image further, 
move the projector further away from the 
screen. (p.15)Turn to Tele to 
reduce the size
Turn to Wide to 
increase the size

Adjusting the Image Angle and Automatic Keystone 
Correction Function
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 11º.
When the projector is tilted, it will cause keystone distortion to appear in the 
image, but this distortion can be corrected using the automatic keystone 
correction function as long as the vertical angle of tilt is within a range of 
approximately 15º*. Automatic keystone correction is carried out 
approximately one second after the projector is set up and projection starts.
* This value applies when the zoom ring is turned to the maximum Tele setting. 
If the zoom ring is turned to the Wide setting, the available angle of tilt for 
automatic adjustment will become smaller.

Tip :
 Automatic keystone correction is not carried out when the Rear or Ceiling 
commands in the Advanced menu are set to ON.
 If you would like to make further adjustments after automatic keystone correction has 
been carried out, you can use the [keystone] button on the projectors control panel. 
(p.36)
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 :
 If the projector is tilted horizontally, turn the bases of the front adjustable feet to adjust 
the angle.
 When keystone correction is carried out, the projected image will become smaller.
 If the images become uneven in appearance after keystone correction is carried out, 
decrease the sharpness setting. (p.49, 50)
 If automatic keystone correction is not required, set Auto Keystone in the Setting 
menu to OFF. (p.52)

Manually Correcting Keystone Distortion
The projector is provided with an automatic keystone correction function which 
detects the vertical angle of the projector and carries out keystone correction 
automatically. If further correction adjustment is required after automatic 
keystone correction has been carried out, use the [Keystone] buttons on the 
projectors control panel to make the adjustment.
Procedure
Tip :
 When keystone correction is carried out, the projected image will become smaller.
 If the images become uneven in appearance after keystone correction is carried out, 
decrease the sharpness setting. (p.49, 50)
 Keystone correction can also be carried out using the configuration menu. (p.52)
 If the value displayed in the gauge on the screen stops changing when horizontal or 
vertical keystone correction is being carried out, it indicates that the limit for 
horizontal or vertical 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, 74)
 If the projector is positioned outside the normal projecting range of 1.0 - 11.7 m (3.2 - 
38.5 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.
Automatic adjustment 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 adjustment is not carried out. If you press the [Auto] button on the 
remote control while computer signals are being projected, automatic adjustment will 
then be carried out.
 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 automatic 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 menu commands to adjust the 
tracking and sync settings manually. (p.49)
