SAFETY SUMMARY

Please read these instructions carefully before using your LP 740.

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 250 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 26 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 bottom of the

projector (see page 26). 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 problem yourself.

Introduction

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 a mainframe computer

room as defined in the Standard for the Protection of Electronic

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 34. Call your In

Focus dealer to order.
