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.
