SAFETY SUMMARY
Please read these instructions carefully before using your LP 420.
Failure to comply with them could result in fire, electrical shock,
personal injury or damage to equipment.
These graphics are used throughout this manual to draw your
attention to important information about the projectors.
NOTE: Additional useful details or tips.
CAUTION: Steps to take to avoid damage to your equipment.
WARNING: Steps to take to avoid personal injury.
These graphics are used on the projector’s labels.
Attention - Refer to this User’s Guide for important
safety information.
CAUTION-Hot Surfaces - Avoid touching hot surfaces.
Do not touch until the projector has cooled.
Do Not Look Into The Lens!
Be extremely careful not to look into the projection lens when the projec-
tor is turned on. The bright light may harm your eyes. Be especially care-
ful to keep children from looking into the lens.
Power Source
Use only a three-wire grounding type power source. The power source
should not exceed 275 volts rms between the supply conductors or
between either conductor and the ground.
Power Cord
Use only the power cord that was shipped with the projector. Although
other power cords might be similar in appearance, they have not been
safety-tested with the projector. Do not use a power cord if it has become
damaged or frayed. Contact your In Focus dealer or call In Focus if you
need to replace your power cord.

Safety Summary
Grounding
The projector is grounded through the grounding conductor on the
power cord. To avoid electric shock, plug the power cord into a properly
wired receptacle. Do not defeat the purpose of the grounding-type plug.
Lamp
To avoid overheating and unacceptable image quality, replace the projec-
tion lamp with a lamp of the specified type. Refer to page 33 for lamp
specifications and to page 25 for instructions on replacing the lamp.
Lamp Compartment
To avoid burns, do not open the lamp module door until the projector is
turned off and the lamp has cooled for at least 30 minutes. Follow the
instructions in this manual for lamp replacement carefully.
Hot Surfaces
Allow the projector to cool at least 30 minutes before replacing a lamp.
When you open the lamp housing, be very careful not to touch the hot
surfaces inside.
Ventilation and Overheating
Openings in the projector case provide ventilation to protect it from
overheating. Keep loose papers and other objects well away from the
grills. Do not place the projector on top of or close to a computer or other
heat-producing equipment.
Liquid Spills
Do not set drinks on top of the projector. Spilled liquids can flow inside
and cause damage.
NOTE: If you open the projector
case, you will void the warranty.
Do Not Disassemble
All service must be performed by an authorized In Focus service center.
The only user-serviceable part in the projector is the projection lamp,
which you can replace by opening the lamp cover on the side of the pro-
jector (see page 25). Do not open any other part of the projector. If your
projector needs repair, call your local Authorized Service Provider or In
Focus Technical Support as described on page 4. Before you call, refer to
“Troubleshooting” starting on page 29 to see if you can resolve the prob-
lem yourself.

INTRODUCTION
The In Focus LP 420™ is specifically designed for the mobile pre-
senter. It packs SVGA graphics with 16.7 million colors into a
small, 6.8 pound package. It generates crisp, clear images using
Digital Light Processing™ (DLP) technology. The LP 420 is easy
to connect, easy to use, and easy to maintain.
NOTE: The 420 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 20 for more infor-
mation.
Image Resolution
The SVGA resolution of the 420’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com-
pressed to 800x600. The 420 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 420.
Compatibility
The projector is compatible with a wide variety of computers and
video devices, including:
•IBM-compatible computers, including laptops, up to 1024x768
resolution.
•Apple Macintosh and PowerBook computers up to 1024x768
resolution.
•Most standard VCRs, camcorders and laser disc players.
Unpacking the Projector
NOTE: The 420 ships standard
with computer and audio cables. If
you want mouse control of your
computer, you must order the
optional CableWizard and remote.
The projector comes with the items shown in Figure 1. Check to
make sure all are included. Contact your In Focus dealer imme-
diately if anything is missing.
If you are experienced in setting up presentation systems, use the
LP 420 Quick Start card that was included in the shipping box. For
complete details on connecting and operating the projector, refer
to this User’s Guide. User’s Guides are also available for down-
load from our website at www.infocus.com.

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 compo-
nents. 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 temper-
ature before use.
This projector is not intended for use in mainframe computer
rooms as defined in the Standard for the Protection of Electronic Com-
puter/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 35.

1Place the projector on a flat surface.
•The projector must be within 10 feet (3 m) of your power
source and within 6 feet (1.8 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 23 to reverse the image.
2Position the projector the desired distance from the screen.
•The distance from the lens of the projector to the screen
determines the size of the projected image. Figure 3 shows
