or online help for details. 
On most systems, the   or 
CRT/LCD key lets you toggle 
between the LCD screen and the projector, or display on both at 
the same time.

Adjusting the Image
Once you see your image, you’ll need to make certain adjustments:
■To focus or zoom your image, see below. 
■If the image is too high or too low, you can reposition it. 
See page 34.
■If the image isn’t square, see page 35.
■To change the color mode for your image and surroundings, see 
page 36.
■If a computer image displays incorrectly, see page 37.
You can make many other adjustments to the image—such as 
changing the brightness, contrast, and aspect ratio—using the 
projector’s menu system. See Chapter 4 for more information

							34Using the ProjectorYou can also change the image size by moving the projector closer to 
or farther away from the screen. You can use the 
E-Zoom buttons on 
the remote control to zoom in on a portion of the image. See page 42 
for instructions. 
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. Press the blue foot release levers on 
each side and lift the front of the projector. This unlocks the feet.
2. Once the image is positioned where you want, release the levers to 
lock the feet in position.
3. To fine-tune the height of the image, 
rotate the projector’s feet.
If the image is no longer rectangular after 
raising it, see the next section.

							Using the Projector35
Adjusting the Image Shape
The projector automatically corrects images that are distorted when 
the projector is tilted up or down (up to a 15° tilt). The Keystone 
window appears on the screen while the projector makes the 
correction. If the projected image still isn’t rectangular 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  , the Auto Keystone feature 
may have been disabled or you may need to manually adjust the 
keystone correction value. (Auto Keystone is not available when 
you’re using ceiling or rear projection.) Follow the directions 
below:
■To turn on Auto Keystone, press the Menu button on the 
remote control. Use the directional button to select the 
Setting menu, then press Enter. If Auto Keystone is OFF, 
press to highlight this option and press 
Enter. Select ON in 
the Auto Keystone window that appears and press 
Enter to 
save your changes. Exit the menu by pressing the
 Menu 
button. 
■To manually adjust the keystone correction value, press the 
 or   side of the 
Keystone button on the projector to 
correct the shape of the image. After correction, your image 
will be slightly smaller.
You can also make keystone adjustments using the projector’s Setting 
menu. See page 52.EnterDirectional buttons Menu 
						

							36Using the Projector
Adjusting the Brightness
The brightness of an image depends on the source you are projecting 
and the amount of light in the room. If the image is too bright or not 
bright enough, here are two ways you can adjust it:
■Change the Brightness setting in the Image menu. See page 49.
■Select Low or High for the Brightness Control option in the 
Advanced menu. (See page 54.) Low brightness mode extends the 
life of the lamp and decreases the fan noise.
Adjusting the Color Mode
You may want to adjust the color mode to select a different setting 
that is appropriate for the image you’re projecting and the 
environment in which you’re projecting it.
If you’re projecting computer or RGB video images, the default color 
mode is 
Presentation, which is appropriate for presentations in 
bright rooms. For other images, the default color mode is 
Dynamic, 
which optimizes video images using natural colors.
The following table lists the 6 color modes available.  
Color mode Description
sRGB Use when projecting computer images conforming to 
the sRGB color standard (the default setting when 
projecting from a computer with analog video)
Dynamic Best for projecting movies with vivid color in bright 
rooms.
Presentation Use when you’re projecting a presentation in a bright 
room.
Theater Use when projecting movies in a dark room.
Living Room Best for playing video games or watching TV in a 
bright room.
Blackboard Choose this fixed color mode when you need to 
project against a green blackboard. 
						

							Using the Projector37
To change the color mode, press the Color Mode button on the 
remote control until you see the mode you want. The currently 
selected setting appears in the upper right corner of the screen. You 
can also use the projector menu system to select the Color Mode in 
the Image menu (see page 49).
Correcting Computer Images
If you’ve connected a computer and the image doesn’t look right, or it 
doesn’t fit properly on the screen, press the 
Auto button on the 
remote control. This automatically resets the projector’s tracking, 
sync, resolution, and position settings. You must be projecting an 
image for this button to have any effect. Additionally, if the 
Auto 
Setup
 option in the Image menu is set to OFF, the Auto function will 
not work. See page 50.
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’re using a computer, shut it down first; otherwise you may 
not be able to see your computer’s display to shut it down 
properly.
2. To turn off the projector, press the P 
Power button on the 
projector or remote control. 
You see this confirmation message: 
(If you don’t want to turn it off, 
press any other button or wait a few 
seconds until it disappears.)

Auto button
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 P 
Power button. You 
can turn Sleep mode on or of
f 
through the Setting menu. 
See page 53. 
						

							38Using the Projector3. Press the P 
Power button again. The lamp is turned off and the 
power light flashes orange for about 20 seconds as the projector 
cools down. When the projector has cooled, the light stays orange 
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 P 
Power button.
4. Retract the front feet as shown.
5. Replace the lens cap and unplug the power cord.
6. Turn off and disconnect any equipment plugged into the 
projector.
7. If you won’t be using the projector for a while, store it in the soft 
case that came with it or in a protective case.
caution
To avoid damaging the 
projector or lamp, never 
unplug the power cord 
when the power light is 
green or flashing orange.

Using the Remote Control
The remote control lets you access your projector’s features from 
anywhere in the room—up to 20 feet away. For example, you can turn 
the projector on and off, freeze the presentation, zoom in on a portion 
of your image, and access the menu system. (The projector menus let 
you adjust many projector settings; see Chapter 4.)
If you’re using a computer and you’ve connected the mouse cable 
as described in Chapter 1, you can use the remote control as a wireless 
mouse.
When using the remote control, stand within 20 feet of the projector. 
Point the remote control either at the front or back of the projector or 
at the screen (the projector’s front sensor can detect signals bounced 
off the screen). Press the button for the function you want to use.
This chapter covers the following information:
■Removing the battery tape
■Storing the remote control
■Controlling the picture and sound
