							Setting Up the Projector31
Connecting External Speakers
You can output sound to external speakers with built-in amplifiers. 
When you play sound through external speakers, the projector’s 
built-in speaker system is disabled.
1. Locate the appropriate cable to connect your speakers. 
Depending on your speakers, you may be able to use a 
commercially available audio cable with a stereo mini-jack 
connector on one end and pin jacks on the other end. For some 
speakers, you may have to purchase a special cable or use an 
adapter.
2. Connect the stereo mini-jack end of the audio cable to the 
Audio Out port on the projector. 
  
3. Connect the other end of the cable to your speakers. 
The projector’s internal speaker system is disabled while sound is 
output to external speakers, and you can’t use the projector or remote 
control to adjust the volume. .

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 36.
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Open the 
A/V Mute slide (lens cover).
2. Connect one end of the power cord to the projector’s power inlet.  
						

							Projecting35
3. Connect the other end to an electrical outlet. The PPower light 
on top of the projector turns orange, indicating that the projector 
is receiving power but not yet turned on. 
4. Turn on your computer or video source if you have not already. 
5. Press the P 
Power button on the projector or on the remote 
control to turn it on. 
The projector beeps and the P
Power light flashes green as the 
projector warms up. The projector lamp comes on in about 
5seconds and the P
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 36.
(With Windows, if you see a message saying that it has found 
a plug-and-play monitor, click 
Cancel.) 
■If you’re projecting a video, you may need to 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 66.
To focus and adjust the image, see page 38. If a projected image fails 
to appear, see “What To Do If You See a Blank Screen” on page 36.
When you’re done, shut down the projector as described on page 42.
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.

Selecting the Image Source
Selecting the image source lets you switch between images input from 
different pieces of equipment connected to the projector (such as a 
computer and DVD player). If you don’t see the image you want, 
press the 
Source Search button on the remote control or projector 
until the correct device image is projected. If a projected image fails to 
appear, see the next section for help.
Once you see your image, turn to page 38 for instructions on focusing 
and making other image adjustments. 
What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No Signal 
after turning on your computer or video source, try the following:
■Make sure the cables are connected correctly, as described in 
Chapter 1.
■Make sure the PPower light is green and not flashing and the 
A/V Mute slide is open. 
■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. 
■Check the Signal menu to make sure the correct input source is 
selected. See page 54.
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. 
note
The name of the selected 
image source appears briefly 
in the upper right corner of 
the screen. 
						

							Projecting37
■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. 
If you’re using a Macintosh laptop with OS X:
You may need to set up your system to display on the projector screen 
as well as the LCD screen. Follow these steps:
1. From the Apple menu, select 
System Preferences, then click 
Display or Displays.
2. Select VGA Display or Color LCD, click Arrange or 
Arrangement, and make sure Mirror Displays is checked.

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 39.
■If the image isn’t square, see page 40.
■To adjust image brightness, see page 40.
■If a computer image displays incorrectly, see page 41.
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, and 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 47 
for instructions.

Adjusting the Height of Your Image
If the image is too high or low, you can correct it by adjusting the 
projector’s front 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.
The projector automatically corrects images that are distorted when 
the projector is tilted up or down (up to a 30° tilt). The Keystone 
window appears on the screen while the projector makes the 
correction. If the projected image still isn’t rectangular, follow the 
instructions in the next section. 
						

							40Projecting
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 may need to turn on Auto Keystone. See page 56 for 
instructions.
You can also make keystone adjustments using the projector’s Settings 
menu. See page 56.
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 53.
■Select Low or High for the Brightness Control option in the 
Settings menu. (See page 57.) Low brightness mode extends the 
life of the lamp and decreases the fan noise.
