Powering up the Projector
NOTE: Always use the power cord 
that shipped with the projector.
1Remove the lens cap.
2Plug the power cord into the back of the projector, then plug it 
into your electrical outlet. A surge-protected power strip is 
recommended.
The LED on the top of the projector (Figure 11 on page 18) 
lights orange after a few seconds.
3After the LED lights orange, press the Power button on the 
projector ’s keypad or remote.
NOTE: The first time you connect 
your computer to the projector, the 
computer may display a message 
stating that new hardware was 
found. The Add New Hardware 
Wizard may appear. Use the Wiz-
ard to load the correct driver (the 
computer considers the projector a 
Plug and Play Monitor). 
The fans start to run, the LED on the top of the projector 
lights green, and the InFocus startup screen appears. It 
takes about one minute for the image to achieve full bright-
ness.
4If you connected a video player, turn it on.
The video image should display on the projection screen. If 
it doesn’t, press the 
Source/Select button on the keypad 
(page 18) or the 
Video button on the remote to display your 
video image.
5If you connected a computer, turn it on. 
The computer image should display on the projection 
screen. If it doesn’t, press the 
Source/Select button on the 
keypad or the 
Computer button on the remote to display 
your computer ’s image. 
NOTE: With some computers, 
the order in which you power up 
the equipment is very important. 
Most computers should be turned 
on last, after all other peripherals 
have been turned on. Refer to your 
computer’s documentation to 
determine the correct order. 
Make sure your laptop’s external video port is activated; 
see “Portable and Laptop Activation Chart” on page 42 for 
details.
If necessary, make adjustments to the image using the pro-
jector ’s on-screen menus. To open the menus, press the 
Menu button on the keypad or remote. For more informa-
tion about the menus, see page 21.

Setting up the Projector
Turning Off the Projector
To turn off the projector, press the Power button. A dialog box 
appears, asking for confirmation. Press the Power button again to 
turn the lamp off. The fans continue to run for a minute, then the 
projector shuts off.
If you want to turn the lamp back on, you must allow 90 seconds 
for the lamp to cool. The lamp won’t light if it’s too hot.
NOTE: To maximize lamp life,
allow the projector to run for at
least five minutes before turning
it off.
If you want to turn off the projector for a short period of time, 
press the 
Po w e r button twice. This puts the projector in standby 
mode. The lamp goes out, and the fans run and the LED blinks 
orange for 1 minute. After 1 minute, the fans turn off and the LED 
lights solid orange. To exit standby mode and return to normal 
operation, press the 
Po w e r button.

USING THE PROJECTOR
This section describes how to use and make adjustments to the 
projector. It also provides a reference to the keypad and remote 
buttons and the options available from the on-screen menus.
Basic Image Adjustment
1Make sure you have powered up your equipment in the right 
order (page 13).
2If the image doesn’t display completely, zoom the image 
(page 15), adjust the height of the projector (page 16) or center 
the image by adjusting its horizontal or vertical position 
(page 24). Be sure the projector lens is at a 90 degree angle to 
the screen.
3If the image is out of focus, rotate the focus ring (page 15).
4If the colors don’t look right, adjust the brightness, contrast, 
tint, or color (page 22).
Adjusting the Projector
To focus the image, rotate the focus ring (Figure 8) until the image 
is clear. To zoom the image, rotate the zoom ring. This adjusts the 
image size.
NOTE: To obtain the best overall 
focus quality, open the menu and 
focus on the text. This will ensure 
that the best overall image quality 
is achieved.

Using the Remote Control
To control the computer ’s mouse from the projector ’s remote, 
you must connect the USB or PS/2 mouse cables to the computer 
and the projector. See page 10 for details. 
Point the remote control at the projection screen or at the front or 
rear of the projector (not at the computer). The range for opti-
mum operation is about 40 feet. If you point the remote at the 
projection screen, the distance to the screen and back to the pro-
jector must be less than or equal to 40 feet. For best results, point 
the remote directly at the projector.
