Adjusting the Screen ImageThese functions correct and adjust the projected images so that optimum 
images can be obtained.Adjusting the Image Size (Zoom Function)
The size of the projected image is basically determined by the distance 
from the projector to the screen. sp.16
The following procedures explain how to adjust the screen image once the 
projector itself has been set up.PROCEDUREAdjust by turning the zoom ring.
The image can be enlarged in this way to 1.2 times the normal size.
If you would like to enlarge the image further, move the projector 
further away from the screen. sp.16
Focusing the Screen Image
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 lets you enlarge parts of the image. sp.52

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. sp.82, p.99
 If the projector is positioned outside the normal projecting range of 
100–1210 cm (3.2–39.7 ft.), it may not be possible to obtain the 
correct focus. If you have trouble obtaining the correct focus, check 
the projection distance.

Adjusting the Screen ImageUser’s GuideAdjusting 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 you can not set up the projetor so that it is at right angle to the screen 
surface, you can tilt the projector up. By extending or retracting the front 
adjustable foot, you can adjust the projection angle upward to a maximum 
12°.Seen from the side

CAUTION
Do not tilt the projector at more than the maximum angle. Doing so 
may cause the projector to fall down or fall off a desk and may result 
in injury.

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.
If you tilt the projector up, keystone distortion will occur in the projected 
screen. However, the projector is equipped with an automatic keystone 
correction function that can automatically correct this keystone distortion 
on the screen. Automatic keystone correction is carried out approximately 
one second after the projector is tilted vertically while the power is on.

 When keystone correction is carried out, the projected image will 
become smaller.
 If the text part of the image is blurred after keystone correction is 
carried out, decrease the sharpness setting. sp.56, p.58
 Keystone correction can also be carried out using the configuration 
menu. sp.62
 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 reached. Check that the 
projector has not been set up at an angle which exceeds the proper 
limit.

Adjusting the Image QualityThe quality of the screen images can be adjusted as follows.Adjusting Computer Images and RGB Video Images
Automatic setup detects analogue RGB signals coming from a connected 
computer, and automatically adjusts these signals so that the optimum 
images can be obtained.
Automatic setup involves adjustment of the following three items:
Tracking
g, Position and Sync (synchronisation)
g.
Automatic Setup
TIP
 If Auto Setup in the Signal menu is set to OFF (the default 
setting for this item is ON), automatic setup is not carried out. In 
this case, press the [Auto] button on the remote control or the [Enter] 
button on the projectors control panel to make the adjustment while 
computer or RGB video images are being projected.
When you press the [Auto] button, the screen will turn to solid black 
colour for a moment and then return to a previous image. The auto 
adjustment is still in progress even after returning to the previous 
image. Wait about 3 seconds before pressing any other buttons.
 If you press the [Auto] button while the E-Zoom function or Freeze 
function is activating, the auto adjustment will start after canceling 
those functions.
 Sometimes the signals may not be adjusted correctly depending on 
the type of computer or RGB video signals being output. In such 
cases, use the configuration menu commands to adjust the tracking 
and sync settings manually. sp.45, p.46
