Positioning the Projector
If the projector isn’t already installed in the room you’re using, 
you’ll probably want to place it on a table in front of the screen. 
This lets you stand in the front of the room, face the audience, 
and remain close enough to the equipment to be able to control 
it. Try to leave as much space as possible between the projector 
and the screen to get a good-size image. 
Use the figure below to help you determine placement. Image 
size increases with distance, but can vary depending on how you 
position the zoom ring and whether you’ve adjusted the image 
with other settings.
Also keep these considerations in mind: 
❏Place the projector on a sturdy, level surface.
❏Make sure there is plenty of space for ventilation around 
and under the projector. Do not set the projector on top of 
anything that could block the vents under the projector. 
❏Make sure the projector is within 10 feet (3 meters) of a 
grounded electrical outlet or extension cord. 
Ideally, you should place the projector directly in front of the 
center of the screen, facing it toward the screen squarely. The 
base of the lens should be at about the level of the bottom of the 
screen. 
If you place the projector below screen level, you’ll have to tilt it 
up by extending the front adjustable foot. This causes the image 
to become “keystone” shaped, but you can correct the 
distortion. (See “Adjusting the Image Shape” on page 6.)
Turning On and Off the Projector
Turn on any connected computer or video equipment before 
starting the projector so it can automatically detect and display 
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 5). 
Follow these steps to turn on the projector: 
1. Open the A/V mute slide (lens cover). 
2. Plug one end of the power cable into the projector, and the 
other end into an electrical outlet.
The 
Power light turns orange.

4 2/08 3. Press the P
Power button on the remote control or on top 
of the projector. 
The projector beeps once and the 
Power light flashes green 
as the projector warms up, then an image begins to appear. 
When the 
Power light stops flashing and remains green, the 
projector is ready for use.
4. If you are prompted to enter a password, see page 9.
Warning: Never look into the lens when the lamp is on. This can 
damage your eyes and is especially dangerous for children.
Using the Direct Power On Function
The Direct Power On function enables faster setup. The 
projector starts up automatically when you plug it in or turn it 
on with a wall switch. You don’t have to press the P
Power 
button.
Follow these steps to enable Direct Power On: 
1. Press the 
Menu button on the remote control or projector 
and select the 
Extended menu. 
2. Choose 
Operation and press Enter. 
3. Choose 
Direct Power On and press Enter.
4. Highlight 
On and press Enter. 
5. Press 
Menu to exit. The setting will take effect the next 
time you plug in the projector.
Note: If a power outage occurs when Direct Power On is enabled 
and the projector is plugged in, the projector will restart when the 
power is restored.
Shutting Down the Projector
This projector incorporates Instant Off technology. To turn it 
off, you can press the P
Power button, unplug it, or turn off a 
power switch that supplies power to the projector. You don’t 
have to wait for the projector to cool off first. 
1. To turn off the projector, press the P
Power button on the 
remote control or projector. You see a confirmation 
message. (If you don’t want to turn it off, press any other 
button.)
2. Press the P
Power button again. The projection lamp 
turns off and you can unplug the power cord. 
If you want to turn the projector on again, make sure the 
orange 
Power light is not flashing, then press the PPower 
button.
Note: Turn off this product when not in use to prolong the life of the 
projector. Lamp life results vary depending on the mode selected, 
environmental conditions, and usage. 
Sleep Mode
You can set the projector to automatically turn off the lamp and 
enter “sleep mode” when it has not received any signals for up 
to 30 minutes. This conserves electricity, cools the projector, 
and extends the life of the lamp. You can enable sleep mode in 
the Extended menu under 
Operation. If you are done using the 
projector, unplug the power cord. If you want to start 
projecting again, press the P
Power button. 
Troubleshooting Display Problems
You Can’t Project an Image
If you don’t see the image you are trying to project, try the 
following: 
❏Make sure the cables are connected correctly.
❏Make sure the 
Power light is green and not flashing and the 
A/V mute slide (lens cover) is open. 
❏If you’ve connected more than one computer and/or video 
source, you may need to press the 
Source Search button 
on the projector’s control panel or the 
Search button on 
the remote control to select the correct source. (Allow a few 
seconds for the projector to sync up after pressing the 
button.)
❏If you’re using a PC notebook, see the next section.

The Projector and Notebook Don’t Display the 
Same Image
If you’re projecting from a notebook, and you can’t see your 
image on the projection screen and on your computer at the 
same time, follow these guidelines:
If you’re using a PC notebook:
❏On most systems, there’s a function key that lets you toggle 
between the LCD screen and the projector, or display on 
both at the same time. It may be labeled 
CRT/LCD or have 
an icon such as  . You may have to hold down the 
Fn 
key while pressing it. Allow a few seconds for the projector 
to sync up after changing the setting. 
❏If the function key doesn’t permit you to display 
simultaneously on both screens, you should 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. In the 
Display Properties dialog box, 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 Mac 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 
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 may need to make certain 
adjustments, as described in this section.
Adjusting the Height of the Image
If the image is too low on the screen, you can use the front 
adjustable foot to raise it. 
1. Stand behind the projector. Press the foot release lever 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 necessary, you can fine-tune the height or level the image 
by turning any of the projector’s adjustable feet. 
Raising the projector causes the image to distort or “keystone,” 
but you can correct the shape as described on page 6.
Focusing and Zooming the Image
To sharpen the image, turn the focus ring on the projector. 
To reduce or enlarge the image, turn the zoom ring on the 
projector. 
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 8 for instructions.

Adjusting the Image Shape
You can maintain a square or 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 placed at an angle, you’ll need to correct the image 
shape by using one of the functions described below. 
Automatic Image Adjustment
Use the projector’s Quick Setup feature to set up quickly for a 
presentation. This function automatically corrects the shape 
and position of the image to fit on a screen with a 4:3 aspect 
ratio. It can correct image distortion when the projector is 
placed up to a 45° angle to the screen (vertically) and 20° 
(horizontally).
1. Press the 
Quick Setup button on the projector’s control 
panel.
You see this message projected:
2. Aim the projector so the message appears near the middle of 
the screen. Then use the zoom ring to enlarge the image so 
the white frame (not shown above) extends beyond the 
edges of the screen on all sides.
3. Press the 
Quick Setup button again. Two white boxes flash 
momentarily onto the screen, and the adjustment is 
complete. Your projected image now fits on the screen 
(some slight overlap is normal).
The Quick Setup adjustment is retained when the projector is 
turned off. If the projector is installed in a fixed location, you 
won’t need to repeat the adjustment each time you turn it on. 
To fine-tune the Quick Setup adjustment, use Quick Corner
®.
Using Quick Corner
Use Quick Corner to adjust the shape and size of the image 
when it’s uneven on all sides, or to finely adjust the image after 
performing Quick Setup. If you just used Quick Setup, you can 
use the projector’s arrow buttons to make the Quick Corner 
adjustment. If not, you’ll have to select 
Quick Corner as 
follows: 
1. Press the 
Menu button on the remote control or on the 
projector’s control panel.
2. Select the 
Settings menu and press Enter. 
3. Select 
Keystone and press Enter. 
4. Select Quick Corner and press Enter.
You see this screen:
5. Use the  pointer button on the remote control (or the 
arrow buttons on the projector) to select the corner you 
want to adjust, and press 
Enter.
6. Use the  pointer button on the remote control (or the 
arrow buttons on the projector) to adjust the shape. 
7. Repeat steps 5 and 6 as needed to adjust any remaining 
corners. 
When done, press 
Menu to exit the menu system.
Using Keystone Correction
The projector automatically corrects vertical keystone distortion 
when it is tilted within a range of 45° up or down.
It takes about one second after projection starts for the image to 
be corrected. During this time, a vertical keystone correction 
gauge appears on the screen. If keystone correction isn’t 
automatically performed, you may need to turn on the 
Auto V-Keystone setting in the projector’s Settings menu.
Corrected image Projector tilted up Projector tilted down 
						

							PowerLite 1825
2/08 7 You can manually adjust the shape of the image to compensate 
for vertical and horizontal keystone distortion. First make sure 
the Keystone setting in the projector’s Settings menu is set to 
H-Keystone or V-Keystone: 
1. Press the 
Menu button on the remote control (or on the 
projector’s control panel).
2. Select the 
Settings menu and press Enter. 
3. Select 
Keystone and press Enter. 
4. Select 
H/V-Keystone and press Enter.
5. Select 
H-Keystone (for horizontal adjustment) or 
V-Keystone (for vertical adjustment) and use the l and r 
arrow buttons to adjust the shape of the image.
Note: The vertical keystone values increase or decrease in .5° 
increments; so 30=15°, 60=30°, etc.
If the image becomes smaller, use the zoom ring to enlarge the 
image so it fits the screen. If the image contains faint lines or a 
gridlike pattern, decrease the sharpness setting.
Resizing Video images
You can use the Resize button on the remote control to adjust 
how an image fits into the display area. Press 
Resize to switch 
the aspect ratio between 4:3 and 16:9. This lets you play certain 
digital video images or movies recorded on certain DVDs in 
16:9 widescreen format. You can also select 
16:9 (Up) or 
16:9 (Down) to reposition videos to accommodate subtitles or 
supertitles.
For computer images, select 
Normal to automatically resize the 
image and make the best use of the display area. 
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, do one of the following:
❏Change the 
Brightness setting in the Image menu. 
❏Select 
Low or High for the Brightness Control option in 
the Setting menu. Low Brightness mode extends the life of 
the lamp and decreases the fan noise.
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.
Press the 
Color Mode button on the remote control, and then

Using the Remote Control
When using the remote control, stand within 20 feet (6 meters) 
of the projector. Point the remote control either at 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. Avoid using the remote under bright fluorescent 
lamps or in direct sunlight, or the projector may not respond 
properly.
Switching Between Picture Sources
If your projector is connected to more than one computer 
and/or video source, you can switch between the different

Use them to switch between equipment connected to the 
port identified on each button, or to use EasyMP.
After you select a source, the screen goes dark for a moment 
before the image appears.
Turning Off the Picture and Sound
You can temporarily turn off the image and sound when you 
want to redirect your audience’s attention. There are two ways 
to do this: 
❏Press the 
A/V Mute button on the remote control. This 
turns the image off and stops the sound. To turn the image 
and sound back on, press the button again.❏Close the A/V mute slide, as shown below:
Stopping Action
To stop the action and keep the current image on the screen, 
press the 
Freeze button. The sound continues.
Note: This function pauses the image, not the sound. Because the 
source continues to transmit signals, when you resume the action, it 
won’t be at the point you stopped it.
To restart it, press the Freeze button again. 
Zooming Part of 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  pointer button 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  pointer button to move around the screen.
❏Press the 
E-Zoom button to zoom out. 
5. When done, press the Esc button to return the image to its 
original size.

Checking Projector Status
If your projector isn’t working correctly, first turn it off, wait for 
it to cool (the 
Power light stops flashing orange), and unplug it. 
Then plug the power cord back in and turn on the projector. If 
this doesn’t solve the problem, check the lights on top of the 
projector.
What To Do When the Lights Flash
