Highlighting Your Presentation
You can display a pointer to call out something on the screen, or draw 
straight or curved lines to emphasize particular points. There are three 
preset pointer tools you can choose from, and each one can be 
customized for a different look.
Using the Pointer Tool
1. To activate the pointer tool, press the Effect button on the 
remote control. A pointer appears on the screen.
If you prefer to use a different style of pointer, continue pressing 
the 
Effect button to select the desired style. Three preset 
options are available, but you can customize the look of each one 
(see page 42).
2. Use the  pointer button on the remote control to position the 
pointer on the screen. 
3. To draw a straight line, place the pointer where you want the line 
to begin and press 
Enter. Move the pointer to where you want the 
line to end, and press 
Enter again. 
4. To draw a curved line, place the pointer at the start of the line, 
then press and hold the 
Enter button until it lights. Then use the 
pointer button to move the pointer and draw on the screen. 
Press 
ESC when done. 
5. If you want to draw additional lines, repeat steps 3 and 4.
6. When done drawing, press 
ESC to clear the screen.

Projecting Images Without a Screen
Even if you don’t have a screen, you can project images onto surfaces 
like blackboards and colored walls without loss of image color. Your 
projector has a sensor that measures the conditions of the projection 
surface and automatically adjusts the colors and shading of your 
image. For example, if you’re projecting onto a surface near a window, 
your image appears clear and well-defined rather than faint.
Making Initial Color Corrections
Press the Wall Shot button on either the remote control or the 
projector’s control panel while projecting an image. 
Wall Shot’s status appears in the upper right corner of your screen. 
Then you see a sequence of colors flash for approximately five seconds 
while the sensor measures the conditions of the projection surface and 
adjusts the image.
When you turn the projector off, the projector stores the correction 
values obtained by the last Wall Shot measurements. This is useful if 
you’re projecting against the same surface and under the same 
conditions. To retrieve these corrections, just press the 
Wall Shot 
button again while projecting an image.
note
If the status message 
indicates that Wall Shot is 
off, press the 
Wall Shot 
button again to turn it on.

							44Using the Remote Control
Adjusting Color Corrections for a New Surface
Adjust the correction values if you’re projecting on a new surface or in 
a new location.
1. Press the 
Wall Shot button on the remote control or projector 
while you’re projecting an image. Wait for the Wall Shot status 
screen.
2. Press the 
Wall Shot button until you see Wall Shot 
Readjustment
 on the status screen. 
You see a sequence of colors flash for about five seconds as the 
projector adjusts the color correction values for the new 
projection surface. 
Operating Your Computer with the 
Remote Control
If you’ve connected a computer to the projector with a USB cable, as 
described on page 56, you can use the remote control in place of your 
computer’s mouse. This gives you more flexibility when delivering 
PowerPoint and other slideshow-style presentations, since you won’t 
have to stand next to the computer to change slides.

■Press the Enter button to left-click, or press it twice to 
double-click; press the 
ESC button to right-click.
■To drag-and drop, hold down the Enter button for about one

Enabling Password Protection
To prevent unauthorized use, you can assign the projector a password. 
If you do, a screen will appear requesting the password whenever the 
projector is plugged in. If an incorrect password is entered three times 
in succession, the projector’s operation is locked and the power cord 
must be disconnected and reinserted to redisplay the password screen. 
If an incorrect password is entered nine times in succession, the user 
must contact the dealer to unlock the projector.
The default setting for the Password Protect function is off. Follow 
these steps to turn password protection on:
1. Press the 
Freeze button on the remote control for about five 
seconds.

in PowerPoint
note
It’s a good idea to write your 
password down. Also, make 
a note of the “Request 
Code: xxxxx” number that 
appears in the Password 
Protect Release screen. If you 
do forget the password, you’ll 
need this code when you 
contact the dealer.
If you leave the projector 
plugged in, the Password 
Protect Release screen will 
not appear. You only need a 
password if you unplug and 
reconnect the power cable.

Connecting to Computers, 
Cameras, and Other 
Equipment
This chapter tells you how to connect the projector to a laptop or 
dekstop computer, or to video equipment, such as a VCR or DVD 
player. You can also connect the projector to a digital camera, video 
camera, external speakers, or an external monitor.
Follow the instructions in this chapter on:
■Connecting to a computer
■Connecting an external monitor
■Connecting video equipment
■Connecting to a digital camera
■Playing sound through the projector 
						

							50Connecting to Computers, Cameras, and Other Equipment
Connecting to a Computer 
You can connect the PowerLite projector to any computer that has a 
standard video output (monitor) port, including desktop models, 
PC notebook and laptop computers, Macintosh PowerBooks and 
iBooks, and hand-held devices. You can connect up to three 
computers at the same time:
■To connect to the Computer port (standard VGA cable 
connection), see page 51.
■To connect using the BNC ports, see page 53.
■To connect using the DVI (Digital Video Interface) port, see 
page 54.
After connecting to the computer, you may also want to:
■connect a USB cable so you can use the remote control as a 
mouse; see page 56
■connect a monitor to the projector so you can view your 
presentation close-up as well as on-screen (not necessary if you’re 
using a laptop); see page 57
■connect an audio cable to play computer audio; see page 65 
note
If you connect a Windows-
based computer to the 
projector, you may see a 
New Hardware Wizard 
saying your computer has 
found a plug-and-play 
monitor; if so, click Cancel.
note
If you’re using a PowerBook 
or an older Macintosh and 
you can’t connect the cable 
to your computer, you may 
need to use the Macintosh 
desktop adapter, as shown 
on page 55 (available from 
EPSON; see page 14).
