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, do one of the following:
■On the EX30 or EX50, press the Source Search button on the 
remote control or the projector until you see the image you want 
to project.
■On the EX70, press the Search button or one of the Source 
buttons on the remote control, or press the 
Source Search 
button on the projector.
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 89 for solutions.
You can also select 
Slideshow to project from a USB device or 
SD card (EX70 only). See page 55 for instructions.

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 44.
■To focus or zoom your image, see page 45. 
■To quickly adjust the color, brightness, or contrast, see page 46.
■To change the image aspect ratio, see page 47.
■If you need to fine-tune the image and/or sound, see Chapter 5.
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 44.  
						

							44Displaying and Adjusting the Image
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.
The  EX50 and EX70 projectors include an 
Auto Keystone function 
that detects and corrects vertical keystone distortion up to 11°. It takes 
about one second after the projector starts for the image to be 
corrected.
If your image is still distorted, or you are using the EX30projector, do 
one of the following:
■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 65). 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.
EX50 or EX70: to enlarge or reduce the image, turn the zoom ring.
EX30: 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 65 
for instructions.
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 51 for instructions.

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
■Presenting a slideshow from a USB device or SD card (EX70 
only) 
						

							50Presenting With the Remote Control
Using the Remote Control
Make sure batteries are installed as described on page 82. 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.
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.
