vertical and horizontal keystone distortion.
Before performing horizontal or vertical keystone, use the lens shift 
function to horizontally center the lens and vertically move the lens to 
the top or bottom (see page 29); otherwise, the distortion will not be 
corrected accurately. Also, the distortion may not be corrected 
accurately for some zoom settings.
1. Press the 
Menu button on the remote control or projector.
2. Select the 
Settings menu and press Enter. 
3. From the Settings menu, select 
Keystone and press Enter.

depending on its aspect ratio.
■Full (PowerLite 4200W only): Displays images using the full 
width of the projection area, but does not retain the aspect ratio. 
4:3 ratio images are elongated horizontally.
■Native (computer images only if you are using the PowerLite

Presenting With the Remote 
Control
The projector includes a number of tools to enhance your 
presentation. All of them can be accessed using the remote control, 
which lets you operate the projector from anywhere in the room—up 
to 49 feet (15 meters) away. 
You can use the remote control to adjust the picture (page 36), as a 
pointer to highlight your presentation (page 38), or to control two or 
more projectors at the same time (page 40). If you have the optional 
wireless mouse receiver, you can also use your remote control as a 
wireless mouse when projecting from a computer (page 39). 
This chapter covers:
■Using the remote control
■Controlling the picture
■Highlighting your presentation
■Operating your computer with the remote control
■Operating two or more projectors with the remote control

Using the Remote Control
Make sure batteries are installed as described on page 82. Follow these 
tips for using the remote control: 
■Point the remote control at the front of the projector or at the 
screen.
■Stand within 49 feet (15 meters) of the projector.
Controlling the Picture
You can use the remote control to preview and select your picture 
sources, temporarily turn off the picture, freeze the action, and zoom 
in on the picture.
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can switch between the different sources: 
■The easiest way to select your source is to press the Search button 
on the remote control (or the 
Source Search button on the 
projector) repeatedly until you see the image you want on the 
screen.
■On the remote control, you can press one of the Source buttons 
to select the connected device you need.
After you select a source, the screen goes dark for a moment before the 
image appears.
note
If a button is pressed longer 
than 30 seconds, the remote 
control stops operating to 
conserve battery power. 
When you release the 
button, normal operation 
resumes.
note
Using the remote under 
bright fluorescent lamps or 
in direct sunlight may affect 
projector response.

Turning Off the Picture
You can temporarily turn off the image by pressing the A/V Mute 
button on the remote control. This turns the image black. To turn the 
image back on, press the button again.
You can have the screen turn blue (using the Display setting as 
described on page 67) or display an image such as a company logo 
when you press the 
A/V Mute button. (See page 64 for more 
information on displaying an image.)
Stopping Action
Press the Freeze button on the remote control to stop the action in 
your video or computer image.

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.
note
Because the source continues 
to transmit signals, when 
you resume the action, it 
won’t be at the point you 
stopped it. 
						

							38Presenting With the Remote Control2. 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.
Highlighting Your Presentation
You can display a pointer to call out important information on the 
screen, and you can choose from three shapes for the pointer.
Using the Pointer Tool
1. To activate the pointer tool, press the Pointer button on the 
remote control. A pointer appears on the screen.
If you prefer to use a different style of pointer, see the instructions

With the optional wireless mouse receiver (see page 9), you can use 
the remote control in place of your computer’s mouse. This gives you 
more flexibility when delivering slideshow-style presentations, since 
you won’t have to stand next to the computer to change slides.

Operating Two or More Projectors With 
the Remote Control
If you’re using more than one projector, you can control all the 
projectors—or just selected ones—by using the projector ID system. 
To operate a projector, set the remote control’s ID to match that of 
the projector. Or you can control all the projectors at once by setting 
the remote control’s ID to zero. 
Setting the Projector ID
The projector’s default ID is set to Off. This lets it respond to 
commands from any remote control. To change the ID, follow these 
steps:
1. Press the 
Menu button on the remote control. You see the 
projector’s menu screen. 
2. Select 
Extended, press Enter, select Projector ID, then press 
Enter again.
