SAFETY SUMMARY

Please read these instructions carefully before using your projec­tor. 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
projector is turned on. The bright light may harm your eyes. Be
especially careful to keep children from looking into the lens.

Power So urce

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.

iii

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
projection lamp with a lamp of the specified type. Refer to
page 49 for lamp specifications and to page 41 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.

NO TE: If you open the projector

case, you will void the warranty.

iv

Ventilation and Overheating

Openings in the projector case provide ventilation to protect it
from overhe ating. Keep loose papers and other ob jects 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.

Do Not Disassemble

All projector 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 41). Do not
open any other part of the projector. If your projector needs
repair, call In Focus Technical Support as described on page 5.
Before you call Technical Support, you may want to refer to
“Troubleshooting” on page 44 to see if you can resolve the prob­lem yourself.

INTRODUCTION

The In Focus

®

LP™ 725 and 735 lightweight multimedia projec­tors combine powerful and sophisticated features with easy-to­use, intuitive controls. Built-in multimedia features include
audio, a palette of 16.7 million colors and active matrix liquid
crystal display (LCD) technology. The 700 series projectors are
ideal for high-performance business, training and imaging appli­cations that demand exceptional color quality. The 725 has SVGA
800x600 graphics, the 735 has XGA 1024x768 graphics. The user
interfaces of the two products are identical; information in this
User’s Guide applies to both products.

Image Resolution

LP 725

The SVGA resolution of the 725’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are co m­pressed to 800x600. The 725 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 725

LP 735

.

The XGA resolution of the 735’s projected image is 1024x768.
Screen resolutions between 1024x768 and 1280x1024 are com­pressed to 1024x768. The 735 cannot compress screen resolutions
above 1280x1024. If your computer’s screen resolution is higher
than 1280x1024, reset it to a lower resolution before you connect

NO TE: The 725 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 35 for more infor­mation.

NOTE: The 735 automatically
expands 640x480 and 800x600
images to 1024x768. You can dis­play these images at their original
resolutions by turning off the Auto
Resize feature. See “Auto Resize”

Usage Guidel ines

•

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. Do not place the projec­tor on cloth table coverings, as they may get sucked up to the
vents. Restricting the air flow can cause it to overheat and turn
off.

•

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 fo r use in a mainf ram e co mputer
room as defined in the Sta ndar d for th e Pr otection of Electr o nic
Computer/Data Processing Equipment, ANSI/NFPA 75.

•

Transport the projector in a vendor-appro ved h ard or soft case.
Part numbers for these cases are listed on page 52. Call your In
Focus dealer to order.

SETTING UP THE PROJECTOR

Place the projector on a flat surface.

1

•

The projector must be within 10 feet (3 m) of your power
source and within 10 feet 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 38 to reverse the image.

•

If you are installing the projector on the ceiling, refer to the

LP 700 Series Ceiling Mount Installation Guide

that comes
with the Ceiling Mount Kit for more information. To turn
the image upside down, see “Ceiling” on page 38. The Ceil­ing Mount Kit is sold separately; see page 52.

Position the projector the desired distance from the screen.

2

•

The distance from the lens of the projector to the screen
determines the size of the projected image. Figure 4 shows
three projected image sizes using the lens at minimum
focusing distance. For more information about image size,
see “Projected Image Size” on page 58.

NO TE: An optional extension
cable, sold separately, lets you
increase the distance between the
projector and your computer to
70 feet (21 m). See “Optional
Accessories” on page 52.

Make sure the projector and your computer are turned off.
