Resizing the Image
Some computer images need to be resized to display in the projector’s 
native format: 1024 × 768 pixels. If only part of your computer image 
is displayed, you can correct it with the 
Resize button. 

Press the Resize button on the control panel. The screen image is 
automatically compressed.

Continue pressing the Resize button to pan around the screen in 
the original resolution. 
If you’re projecting from video equipment, pressing the 
Resize 
button switches the aspect ratio between 4:3 and 16:9. If you’ve 
zoomed in on your image (using the 
E-Zoom button on the remote), 
you can press the 
Resize button to return it the original display size.
Adjusting the Height of Your Image
If the image is too low, you can raise it by extending the projector’s 
feet. 
1. Stand behind the projector. Pull up the blue foot release levers 
and lift the front of the projector. This unlocks the feet.
2. Once the image is positioned where you want it, release the levers 
to lock the feet in position.
3. To fine-tune the height of the image, rotate the thumb wheels 
attached to the projector’s feet.
If the image is no longer square after raising it, see the next section.

							26Using the Projector
Adjusting the Image Shape
If the projected image isn’t square or has a “keystone” shape, do one or 
more of the following:

If your image looks like   or  , you’ve placed the 
projector off to one side of the screen, at an angle. Move it directly 
in front of the center of the screen, facing the screen squarely.

If your image looks like   or  , press the + or — side of 
the 
Keystone button to correct the shape of the image. After 
correction, your image will be slightly smaller.
You can also perform electronic keystone correction using the 
projector’s Setting menu. See page 52.
Adjusting the Tracking and Synchronization
If you’re projecting from a computer and you notice vertical stripes or 
the image is flickering or noisy, you can increase the clarity by pressing 
the   button on the control panel (or the 
Auto button on the remote 
control). This resets the projector’s tracking, sync, and position 
settings. If necessary, you can also correct the image manually using 
the 
Tracking and Sync buttons on the control panel.

Press the Tracking – and Tracking + buttons to eliminate vertical 
stripes.

Press the Sync – and Sync + buttons to eliminate flashing, 
blurring, or vertical noise on the screen image.

							Using the Projector27
Controlling the Projector
While giving your presentation, you may want to switch between 
picture sources, adjust the volume, or temporarily turn off the picture 
and sound. Follow the instructions below to access theses features 
from your projector’s control panel. You can also access these features, 
as well as many others, by using the remote control as described in 
Chapter 3. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can use the buttons on the control panel (or remote 
control) to switch between the different sources. 
On the control panel, press the 
Computer button to switch between 
the computer sources and press the 
Video button to switch between 
standard (composite) video, S-Video, and component video (BNC). 
After you select a source, the screen goes dark for a moment before the 
image appears.
Adjusting the Volume
If your presentation includes sound, you can adjust the volume with 
the 
Volume button on the projector’s control panel. Hold the Shift 
button down while pressing the
 + or — side of the Volume button.
Turning Off the Picture and Sound 
You can use the A/V Mute button on the control panel to turn off the 
image and sound and darken your screen. This is useful if you want to 
temporarily re-direct your audience’s attention without the distraction 
of a bright screen.

To turn off the picture, press the A/V Mute button. The screen 
goes dark.

To turn the image back on, press the button again.

							28Using the Projector
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. If you’ve connected a computer or laptop and it’s displaying only 
through the projector (the computer’s monitor is disconnected or 
turned off), shut down the computer first; otherwise you won’t be 
able to see your computer’s display if you try turning it off after 
the projector. 
2. To turn off the projector, press the red 
Power button on the 
projector or remote control. You see a confirmation message. (If 
you don’t want to turn it off, press any other button.)
3. Press the 
Power button again. The power light flashes orange for 
about a minute as the projector cools down. When the projector 
has cooled, the orange light stays on and the exhaust fan shuts off.
If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the 
Power button.
4. Replace the lens cap and unplug the power cord.
5. If you’re using a VCR or other video source, turn it off after you 
turn off the projector.
6. Disconnect all equipment, and store the projector in a protective 
case.
note
When the projector has not 
received any input signals for 
30 minutes, it automatically 
turns off the projector lamp 
and enters “sleep mode.” This 
conserves electricity, cools the 
projector, and extends the life 
of the lamp. If you are done 
using the projector, unplug 
the power cord. If you want 
to start projecting again, press 
the Power button.

caution
To avoid damaging the 
projector or lamp, never 
unplug the power cord 
when the power light is 
green or flashing orange.

If you’ve connected the mouse cable (as described in Chapter 1 or 
Appendix A), you can even use the remote control as a wireless mouse 
to control your computer or click through your slideshow-style 
presentations.
This chapter covers the following information:
