Projecting
Once you’ve set up the projector, you’re ready to turn it on, adjust 
the image, and give your presentation. 
Although you can operate the projector without it, the remote control 
lets you use additional features. See Chapter 3 for instructions on 
using the remote. This chapter covers the following:
■Turning on the projector and other equipment
■Adjusting the image
■Adjusting the volume
■Shutting down the projector

Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1. Then turn on your 
projector, as described below.
If you turn on your connected computer or video equipment before 
starting the projector, the projector automatically detects and displays 
the image source. If you turn on the projector first, or have multiple 
pieces of connected equipment, you may have to select the image 
source manually. See page 34.
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Push in the tabs and remove the lens cap.
2. Connect one end of the power cord to the projector’s power inlet. 
3. Connect the other end to an electrical outlet. 
The power light on top of the projector turns orange, indicating 
that the projector is receiving power but not yet turned on. Wait 
until the light stops flashing but stays orange.
caution
Do not use the projector with 
the lens cap in place. The 
heat generated by the lamp 
can damage it.

4. Turn on your computer or video source if you have not already. 
5. Press the P 
Power button on top of the projector to turn it on. 
(You can also press the P 
Power button on the remote control.)
The projector beeps and the power light flashes green as the 
projector warms up. The projector lamp comes on in about 4 
seconds and the power light stays green. 
■If you’re using a computer, you should see your computer 
display projected after a moment or two. If not, you need to 
select the image source. See page 34.
(Windows only: If you see a message saying that it has found 
a plug-and-play monitor, click 
Cancel.) 
■If you’re projecting a video, press the Source Search button 
on the projector or remote control to switch to your video 
source. Then press the 
Play button on your DVD player or 
other device.
■If you are prompted to enter a password, see page 67.
To focus and adjust the image, see page 37. If a projected image fails 
to appear, see “What To Do If You See a Blank Screen” on page 34.
When you’re done with your presentation, shut down the projector as 
described on page 41.
note
If you are using the remote 
control for the first time, be 
sure to insert the batteries as 
described on the Quick 
Setup poster.

Chapter 1.

cap is off. 
■Make sure you’ve selected the correct image source; see the 
previous section. Allow a few seconds for the projector to sync up 
after pressing the button.

If you’re using a PC laptop:
■Hold down the Fn key and press the function key that lets you 
display on an external monitor. It may have an icon such as   
or it may be labelled 
CRT/LCD. Allow a few seconds for the 
projector to sync up after pressing it. Check your laptop’s manual 
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. 
■If you’re projecting from a laptop, and you don’t see the same 
image on the projection screen and computer screen, check your 
monitor settings to make sure both the LCD screen and the 
external monitor port are enabled. 
From the Control Panel, open the 
Display utility. Click the 
Settings tab, then click Advanced. The method for adjusting 
the settings varies by brand; you may need to click a 
Monitor tab, 
then make sure the external Monitor port is set as your primary 
display and/or enabled. See your computer’s documentation or 
online help for details.

Adjusting the Image
Once you see your image, you’ll need to make certain adjustments:
■To focus or zoom your image, below. 
■If the image is too high or too low, you can reposition it. 
See page 38.
■If the image isn’t square, see page 39.
■To adjust image brightness, see page 39.
■If a computer image displays incorrectly, see page 40.
■To change the color mode for your image and surroundings, see 
page 40.
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.
Focusing and Zooming Your Image
Rotate the focus ring to sharpen the image.
Rotate the zoom ring to reduce or enlarge the image.
You 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 45 
for instructions.

Adjusting the Height of Your Image
If the image is too low, you can raise it by extending the projector’s 
front adjustable foot.
 
1. Stand behind the projector. Press up on the blue foot release 
lever and lift the front of the projector to extend the front 
adjustable foot.
2. Once the image is positioned where you want, release the lever to 
lock the foot in position.
3. To fine-tune the height of the image, 
rotate the foot at the back of the 
projector.
If the image is no longer rectangular after 
raising it, see the next section.

Adjusting the Image Shape
If the projector is tilted up or down, the images that are displayed will 
be distorted. To correct the distortion or “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  , you need to adjust the 
keystone correction value. Press the   or   buttons 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 Settings 
menu. See page 59.
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 54.
■Select Low or High for the Brightness Control option in the 
Settings menu. (See page 59.) Low brightness mode extends the 
life of the lamp and decreases the fan noise.

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 a 
computer image for this button to have any effect. Additionally, if the 
Auto Setup option in the Signal menu is set to OFF, the Auto 
function will not work. See page 57.
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. 
The following table lists the color modes available.  
Color mode Description
Photo Best for projecting still images with vivid color in a 
bright room (Computer input only).
