Selecting an Image Source
You may need to select the image source if you have multiple image 
sources connected to the projector (such as a computer or DVD 
player). Selecting the image source lets you switch between images 
input from different pieces of connected equipment. 
If you don’t see the image you want, press the 
Source Search button 
on the remote control or the projector until you see the image you 
want to project
If you still can’t see an image or can’t project the same image that is on 
your notebook or computer screen, see page 71 for solutions.
Adjusting the Image
Once you see your image, you may need to make certain adjustments:
■If the image is too high or too low, reposition it as described 
below.
■If the image isn’t square, see page 33.
■To focus or zoom your image, see page 34. 
■To quickly adjust the color, brightness, or contrast, see page 35.
■To change the image aspect ratio, see page 35.

Adjusting the Position of the Image
If the image is too low on the screen, you can use the front adjustable 
foot to raise it. 
1. Press the 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 the image is tilted or you need to fine-tune the height of the 
image, you can turn the projector’s adjustable rear feet.
Raising the projector may cause the image shape to distort or 
“keystone,” but you can correct the shape as described on page 33. 
Adjusting the Image Shape
You can maintain a rectangular image by placing the projector directly 
in front of the screen and keeping it level. This also produces the best 
picture quality. If the projector is tilted up or down (up to 30°), or 
placed at an angle, the shape may “keystone” and you may need to 
correct the image shape.
If your image is still distorted, do one of the following: 
						

							34Displaying and Adjusting the Image
■Press the appropriate keystone correction button on the 
projector’s control panel until the shape is evenly rectangular.
■Select the Keystone setting in the projector’s Settings menu (see 
page 49). Then use the arrow buttons on the remote control to 
adjust the shape of the image.
Focusing and Zooming the Image
Turn the focus ring on the projector to sharpen the image.
To enlarge or reduce the image, press the 
Wide (enlarge) or Tele 
(reduce) button on the projector’s control panel. You can also use the 
Zoom setting in the projector’s Settings menu; see page 49 for 
instructions.
If the image still isn’t large enough, you may need to move the 
projector farther away from the screen.

Selecting the Color Mode
The Color Mode adjusts the brightness, contrast, and color for various 
common viewing environments. Use this setting to quickly obtain a 
good picture.
You can select the

displays. 
■Blackboard: Projects accurate colors on a green chalkboard 
(adjusts the white point).
■Sports: For vivid TV images in a bright room (only available for 
component video, S-Video, or composite video sources). 
Resizing Video Images
You can resize your images by changing the aspect (width to height) 
ratio (depending on your input signal).
You can select the 
Aspect setting only from the projector’s Signal 
menu. See page 47 for instructions.
note
You cannot change the 
aspect ratio when displaying 
from a computer using the 
USB TypeB port . 
						

							36Displaying and Adjusting the ImageSelect from one of these 
Aspect options:
■Normal (for images sent through the Computer (Component 
Video)
 port only): Displays images using the full projection area 
and maintains the aspect ratio of the image. Choose this setting to 
automatically resize the image and make the best use of the 
display area.
■4:3: Displays images using the full projection area at an aspect 
ratio of 4:3.
■16:9: Converts the aspect ratio of the image to 16:9. 4:3 ratio

Presenting With the Remote 
Control
The projector includes a number of tools to enhance your 
presentation. All of them can be accessed using the remote control, 
which lets you operate the projector from anywhere in the room—up 
to 19.7 feet (6 meters) away. 
This chapter covers:
■Using the remote control
■Controlling the picture and sound
■Operating your computer with the remote control 
						

							38Presenting With the Remote Control
Using the Remote Control
Make sure batteries are installed as described on page 64. Follow these 
tips for using the remote control: 
■Point the remote control at the front or back of the projector, or 
at the screen.
■Stand within 19.7 feet (6 meters) of the projector.
■Aim the remote control within 30° to the side of, or 15° above or 
below, the remote control receivers on the projector.
Controlling the Picture and Sound
You can use the remote control to temporarily turn off the picture and 
sound, freeze the action, zoom in on the picture, and adjust the 
volume. 
Turning Off the Picture and Sound 
Press the A/V Mute button on the remote control or close the 
A/V Mute slide on the projector 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 the image and sound back on, press the button again, or open 
the 
A/V Mute slide.
You can create an image, such as a company logo or picture, to display 
on the screen whenever you press the 
A/V Mute button. (See page 54 
for more information.)
note
If a button is pressed for 
longer than 30 seconds, the 
remote control stops 
operating to conserve battery 
power. When you release the 
button, normal operation 
resumes.
Using the remote control 
under bright fluorescent 
lamps or in direct sunlight 
may affect projector 
response.

							Presenting With the Remote Control39
You can also set the Lens Cover Timer setting to automatically turn 
off the projector after 30 minutes to protect the projector if the 
A/V Mute slide is closed for a long time. See page 50 for instructions.
Stopping Action
Press the Freeze button on the remote control to stop the action in 
your video or computer image. The image freezes but the sound 
continues.
To restart the action, press the 
Freeze button again.
Zooming In on Your Image
You can zoom in on a portion of the image using the E-Zoom buttons 
on the remote control. 
1. Press the 
E-Zoom + button on the remote control. 
You see a crosshair indicating the center of the zoom-in area.
2. Use the arrow buttons to position the crosshair.
3. Continue pressing the 
E-Zoom + button to enlarge the selected 
area up to 4 times.
4. While the image is enlarged, you can:
■Use the arrow buttons to move around the screen.
■Press the E-Zoom – button to zoom out. 
5. Press the 
ESC button to return the image to its original size.
note
The Freeze function pauses 
the image, not the sound. 
Because the source continues 
to transmit signals, it will 
not resume at the same 
point.

Controlling the Volume
To change the volume on the projector, press the Volume button, 
then press the r button to increase the volume or the l button to 
decrease it.
You can also adjust the volume using the projector’s menu system. 
Seepage49. 
Operating Your Computer With the 
Remote Control
You can use the remote control in place of your computer’s mouse so 
you won’t have to stand next to the computer to control the 
presentation.
If you are not using the projector’s USB 
TypeB port to display your 
presentation, you can use the remote control buttons to do one of the 
following:
■Move through presentation slides using the Page Up (+) or Page 
Down
 (–) buttons
■Use the buttons as you would a wireless mouse by pressing the 
arrow, 
Enter, and Esc buttons
Before you can use one of these functions, you must connect a USB 
cable to the USB 
TypeB port on the projector (see page 19) and select 
the function you want to use.
note
To temporarily shut off the 
sound and picture, press the 
A/V Mute button or close 
the A/V Mute slide.
