INTRODUCTION
The InFocus®LP™425z and LP435z lightweight multimedia pro-
jectors are specifically designed for the mobile presenter. They
generate crisp, clear images using Digital Light Processing™
(DLP) technology. The projectors are easy to connect, easy to use,
and easy to maintain. The soft carry case makes it easy to trans-
port the 7.4 pound projectors. The 425z has SVGA 800x600 graph-
ics, the 435z has XGA 1024x768 graphics. The user interfaces of
the two products are identical; information in this User’s Guide
applies to both products.
NOTE: The 425z automatically
expands 640x480 images to
800x600. You can display these
images at 640x480 by turning off
the Auto Resize feature. See “Auto
Resize” on page 28.

The SVGA resolution of the 425z’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com-
pressed to 800x600. The 425z cannot compress screen resolutions
above 1024x768. If your computer’s screen resolution is higher
than 1024x768, reset it to a lower resolution before you connect
the projector.
LP435z
NOTE: The 435z automatically
expands 640x480 and 800x600
images to 1024x768. You can dis-
play these images at their original
resolutions by turning off the Auto
Resize feature. See “Auto Resize”
on page 28.

Usage Guidelines
•Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.
•Do not block the grills on the projector. Restricting the air flow
can cause it to overheat and turn off. If this happens, you must
wait a minute before attempting to turn it back on.
•Handle the projector as you would any product with glass
components. Be especially careful not to drop it.
•Avoid leaving the projector in direct sunlight or extreme cold
for extended periods of time. If this happens, allow it to reach
room temperature before use.
•This projector is not intended for use in mainframe computer
rooms as defined in the Standard for the Protection of Elec-
tronic Computer/Data Processing Equipment, ANSI/NFPA 75.
•Transport the projector in a vendor-approved hard or soft case.
Part numbers for these cases are listed on page 48.

Introduction
Warranty
This product is backed by a limited two-year warranty. The
details of the warranty are printed at the back of this manual. A
longer term warranty can be purchased from your InFocus
dealer. Refer to page 48 for the part number.

SETTING UP THE PROJECTOR
1Place the projector on a flat surface.
•The projector must be within 10 feet (3 m) of your power
source and within 8 feet (2.4 m) of your computer.
•If you want to project from behind a translucent screen, set
up the projector behind your screen. See “Rear Projection”
on page 31 to reverse the image.
•If you are installing the projector on the ceiling, refer to the
Ceiling Mount Installation Guide that comes with the Ceiling
Mount Kit for more information. To turn the image upside
down, see “Ceiling Projection” on page 30. The Ceiling
Mount Kit is sold separately; see page 48.
2Position the projector the desired distance from the screen.
•The distance from the lens of the projector to the screen and
the zoom setting determine the size of the projected image.
Figure 4 shows three projected image sizes. For information
about image sizes at minimum and maximum zoom set-
tings, see “Projected Image Size” on page 55.
3Make sure the projector and your computer are turned off.

Setting up the Projector
Connecting the CableWizard™3to the Projector
CAUTION: Turn off the
computer, monitor and projector
whenever you connect or
disconnect cables.
The CableWizard3(referred to as “CableWizard” in this manual
for brevity) simplifies the connection process by providing a cen-
tral hub for all the connections between the projector and your
computer. The connectors on the CableWizard are labeled with
icons. The CableWizard also has an LED that lights solid green
when the projector is on and CableWizard is functioning prop-
erly. A slowly blinking LED indicates CableWizard is waiting to
initialize with the projector; a rapidly blinking LED indicates a
problem with CableWizard.
Connect the end of the CableWizard cable to the
connector on the projector’s connector panel (Figure 5).
NOTE: The projectors are
optimized for use with newer
CableWizards (2 and 3). If you
have a CableWizard 1from older
models of InFocus projectors, we
do not recommend using it as
image quality is reduced. The label
on the bottom reads CableWizard
or CableWizard II or
CableWizard3.
FIGURE 5
Connecting the CableWizard to the projector
NOTE: In some older computers,
the monitor connector does not
have a hole for Pin 9. If you have
trouble connecting the
CableWizard cable to your
computer, contact InFocus
Technical Support.

Preparing to Connect Your Equipment to the Projector
NOTE: Before you continue,
make sure the projector and your
equipment are turned off. If you’re
connecting a computer, make sure
the distance between it and the
projector is 10 feet or less.
Now you’re ready to connect your equipment. Computers are
connected to the CableWizard. Video players are connected
directly to the projector.
Steps for connecting the different types of equipment are given
on the pages listed below.
NOTE: The computer audio in
connector on the connector panel
is only used with the optional
CableWizard Lite cable. If you are
using CableWizard, the audio
cable should be connected to the
CableWizard, not directly to the
projector.

The projector is compatible with these major broadcast video
standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM.
It automatically adjusts to optimize its performance for the
incoming video. The input signals for SECAM, PAL-M, and
PAL-N video are similar to other video signals and cannot be
automatically detected, therefore they must be chosen manually.
