Adjusting the projection size
Lens shift adjustment
The size of the projected image is basically determined by the distance from the projectors lens 
to the screen.
Hanging from the ceiling
A screen in a high location
Projector situated to the side so that the screen can be viewd sitting right in front of it
Projector situated on a shelf, etc.
When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens 
shift correction is adjusted optically. 
The lens shift dials can be used to position the image and is especially useful when using the 
projector in the following locations.      p.16 While referring to the table below, position the projector so that the images are projected onto the screen 
at the optimum size.
The values should be used as a guide for setting up the projector.
Be sure to read the separate Safety 
Instructions/World-Wide Warranty 
Te r m s
 booklet before installing the 
projector.
Do not stand this projector upright. 
This may damage your projector.
The height from the centre of the lens to the
bottom of the screen will vary depending on 
the lens shift setting.

Setting up
Installing the Projector
Projection methods
Avoid setting the projector up in places which are very dusty such as bedrooms.
Clean the air filter at least once every 3 months.
Clean the air filter more frequently if using the projector in a dusty environment.
When installing against a wall, leave a space of 20 cm (7.9 in.) or more between the projector 
and the wall.
A special method of installation is required in order to suspend the projector from the ceiling.
Please contact your dealer if you would like to use this installation method.
TIP
*You cannot shift the image by the full amount 
both vertically and horizontally.
Standard projection 
position 
(centre position for lens shift)
Ex) When the image is shifted horizontally 
by the full amount, it cannot be shifted 
vertically by more than 36 % of its 
height.
And when the image is shifted vertically 
by the full amount, it cannot be shifted 
horizontally by more than 17 % of its 
width.

Connecting Image Sources
*1 If a DVD has been connected using an RGB SCART adapter, change the InputA setting to RGB-
Video.   Selecting the image source p. 15
*2 Some regions may not have the RGB SCART adapter included as an accessory.
•Turn the power off for both the projector and the signal source before connecting them. 
If the power for either device is on at the time of connection, damage may result.
•Check the shapes of the cable connectors and the device ports before making the 
connections. If you try to force a connector to fit a device port with a different shape or 
number of terminals, a malfunction or damage to the connector or port may result.
•Some signal sources may have specially-shaped ports. In such cases, use the accessory or 
optional cables that are supplied with the signal source to make the connections.
•The cable that should be used to connect video equipment to the projector will depend on 
the type of video signal that the equipment outputs. Some kinds of video equipment output 
several different types of video signal. The image quality ranking of the video signal types is 
generally held to be as follows, in descending order of quality:
Component video
 > S-Video > Composite video
You should refer to the documentation provided with the video equipment being used to 
check what types of video signal formats the equipment can output. The composite video 
format is sometimes simply called video output.

The remote control is not supplied with batteries already inserted. Insert the accessory batteries before using 
the remote control.
Battery replacement period
If delays in the responsiveness of the remote control occur or if it does not operate after it has been used for 
some time, it probably means that the batteries are becoming flat. If this happens, replace the batteries with 
two new batteries.  Use two new AA batteries as replacement batteries.

Use the two lens shift dials to adjust the image position.
If you cannot position the projector straight 
in front of the screen, use the lens shift dial 
so that the image is centered on the screen.
If the lens shift dial becomes hard to turn further and the image position stops 
changing, no further adjustment is possible.      p.10 Lining up the marks on the shift dial and top surface brings the lens to the centre.

TIP
TIP
Correcting keystone distortion (Keystone)
When you wish to adjust the projection above or below the range of lens shift 
adjustment set the projector at an angle.
When the projector is angled, the projected image may distort into a trapezoid. In such 
cases, press        (   )      (   ) on the control panel, or                    on the remote control 
to adjust the images.
However, the image quality will decrease compared to if the lens shift function is used. 
When the lens is shifted to the left or right, complete keystone correction is not 
possible. When making keystone corrections set the lens at the centre left to right.
Adjusting the volume
The volume of the projectors built-in speaker can be adjusted as follows.
When the button is pressed to the       side, the volume increases,  and when it is pressed to 
the      side, the volume decreases.
Keystone distortion can be corrected within a maximum vertical angle of approximately 30.
You can also make adjustments from the configuration menu.       p.28
To reset the correction value, press and hold down       with       pressed down for at 
least 1 second on the control panel.
You can also make adjustments from the configuration menu.       p.30
