Adjusting the Image 
Once you see your image, you need to make certain adjustments:    
■If the image is too high or too low, you can reposition it. See 
below.
■To focus or zoom your image, see page 23. 
■If the image isn’t square, see page 23.
■If a computer image displays incorrectly, see page 25. 
■If you need to fine-tune the image and/or sound, see Chapter 6.
Adjusting the Height of Your Image 
If the image is too low on the screen, you can use the front adjustable 
foot to raise it. 
1. Stand behind the projector. Press the blue foot release lever up 
and lift the front of the projector. 
2. Once the image is positioned where you want it, release the lever 
to lock the foot in position.
3. If necessary, you can fine-tune the height or level the image by 
turning the projector’s adjustable rear foot. 
Raising the projector causes the image to distort or “keystone,” but 
you can correct the shape as described on page 23.

Focusing and Zooming Your Image 
Turn the focus ring on the projector to sharpen the image. 
Turn the zoom ring on the projector to reduce or enlarge the image. 
If the image still isn’t large enough, you may need to move the 
projector farther away from the screen. You can also use the 
E-Zoom 
buttons on the remote control to zoom in on a portion of the image. 
See page 31 for instructions. 
Adjusting the Image Shape 
In most cases, you can maintain a square or rectangular image by 
placing the projector directly in front of the center of the screen with 
the base of the lens level with the bottom of the screen. 
Even if the projector is slightly tilted (within a range of 30° up or 
down), the projector has an automatic keystone correction function 
that detects and corrects vertical keystone distortion.
It takes about one second after projection starts for the image to be 
corrected. During this time, a vertical keystone correction gauge 
appears on the screen. 
If your image is still distorted, you can correct it using the Keystone 
buttons on the projector’s control panel or the projector’s Setting 
menu.

Using Keystone Correction
To adjust your image when it is wider on the top or bottom, do the 
following:
■Press one of the two triangular buttons on the projector’s control 
panel, as shown below. Continue pressing the button until you 
are satisfied with the shape of the image.
■Or press the Menu button on the remote control or projector, 
select the 
Setting menu, and press Enter. 
From the Setting menu, select 
Keystone and press Enter. Use 
the  pointer button on the remote control to adjust the 
keystone setting as needed. 
If the image becomes uneven, decrease the sharpness setting. (See 
page 113.)
note
The image will be slightly 
smaller after adjusting. If 
it’s important to maintain 
the correct aspect ratio, use 
the menu system to perform 
keystone correction, then use 
the remote’s 
Resize button 
to adjust the aspect ratio. See 
page 32.

Correcting Computer Images
If you’re connected to a computer and the image doesn’t look right, 
press the 
Auto button on the remote control or the Enter button on 
the projector. This automatically resets the projector’s tracking, sync, 
resolution, and position settings. 
If the 
Auto button doesn’t correct the problem, you may need to 
adjust the tracking or sync using the projector’s Signal menu. See 
page 114 for more information.
Shutting Down the Projector
When you’ve finished using the projector, follow the recommended 
procedure to shut it down. This extends the life of the lamp and 
protects the projector from possible overheating. 
1. Turn off any equipment plugged into the projector. 
2. To turn off the projector, press the red P
Power button on the 
remote control or projector. 
You see a confirmation message. (If 
you don’t want to turn it off, press 
any other button.)
note
You must be projecting an 
image for this button to have 
any effect. The 
Auto button 
works only with computer 
images projected through the 
VGA port.
note
Lamp life results will vary 
depending on mode selected, 
environmental conditions, 
and usage.
Turn off this product when 
not in use to prolong the life 
of the projector.  
						

							26Displaying and Adjusting the Image3. Press the P
Power button again. The lamp turns off. When the 
projector beeps twice, you can unplug the power cord. 
(If the projector is mounted on the ceiling, you will need to wait 
20 seconds for the projector to cool down before you can unplug 
the power cord.)
If you want to turn the projector on again, make sure the orange 
light is not flashing, then press the P
Power button.
4. If you extended the adjustable front foot, press up on the blue 
foot release lever to retract it.
5. Close the A/V Mute slide.
Using the Direct Power On Function
The Direct Power On function enables faster setup. The projector will 
start up automatically when you plug it in; you won’t have to press the 
P
Power button. 
Follow these steps to enable Direct Power On: 
1. Press the 
Menu button on the remote control and select the 
Extended menu. 
2. Choose 
Operation and press Enter. 
3. Choose 
Direct Power On and press Enter.
4. Highlight 
On and press Enter. 
5. Press 
Esc or Menu to exit. 
The setting will take effect the next time you plug in the projector.
note
You can set the projector to 
automatically turn off the 
projector lamp and enter 
“sleep mode” when it has 
not received any signals for 
30 minutes. This conserves 
electricity, cools the 
projector, and extends the 
life of the lamp. If you want 
to start projecting again, 
press the 
P Power button. 
If you are done using the 
projector, unplug the power 
cord. To enable sleep mode, 
see page 122. 
note
If a power outage occurs 
when Direct Power On is 
enabled and the projector is 
plugged in, the projector will 
start when the power is 
restored.

							Using the Remote Control29
Controlling the Picture and Sound
You can use the remote control to preview and select your picture 
sources, temporarily turn off the picture and sound, freeze the action, 
zoom in on the picture, and adjust the volume. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can switch between the different sources: 
■The easiest way to select your source is to press the Search button 
on the remote control (or the 
Source Search button on the 
projector) repeatedly until you see the image you want on the 
screen. 
■On the remote control, there are four Source buttons. Use them 
to switch between equipment connected to the port identified on 
each button, or to use EasyMP to project wirelessly or from a 
USB drive.
After you select a source, the screen goes dark for a moment before the 
image appears. 
						

							30Using the Remote Control
Turning Off the Picture and Sound

the 
Freeze button. The sound continues. 
■To restart it, press the Freeze button again. 
note
This function pauses the 
image, but not the sound. 
Also, because the source 
continues to transmit 
signals, you won’t resume 
the action from the point 
you stopped it.
