SAFETY SUMMARY

Please read these instructions carefully before using your
LitePro 720 or 730. Failure to comply with them could resu lt 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 LitePro labels.

Attention - Refer to this User’s Guide for important

safety information.

Hot Surfaces - Avoid touching hot surfaces. Do not

touch until the LitePro has cooled.

Do Not Look Into The Lens!

Be extremely careful not to lo ok into the projection lens when the
LitePro is turned on. The bright light may harm your eyes. Be
especially careful 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 LitePro.
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

T o avoid over heating and unacce ptable image quality, replace the
projection lamp with a lamp of the specified type. Refer to
page 51 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 2 minutes.
Follow the instructions in this manual for lamp replacement care­fully.

Hot Surfaces

Allow the projector to cool at least 2 minutes before replacing a
lamp. When you open the lamp housing, be very careful not to
touch the hot surfaces inside.

NOTE: If you open the LitePro

case, you will void the warranty.

iv

Ventilation and Overheating

Openings in the projector case provide ventilation to protect it
from overheating. Keep loose papers and other obj ects 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 LitePro service must be performed by an authorized In Focus
service center. The only user-serviceable part in the LitePro 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 LitePro. If your LitePro needs repair, call In
Focus Technical Support as described on page 5. Before you call
Technica l Support, you may want to refer to “Trou bleshooting”
starting on page 45 to see if you can resolve the problem yourself.

INTRODUCTION

The In Focus LitePro

720 and 730 lightweight multimedia pro­jectors combine powerful and sophisticated features with easy­to-use, intuitive controls. Built-in multimedia features include
audio, a palette of 16.7 million colors a nd a c tive 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 720 has SVGA
graphics, the 730 has XGA graphics. The user interfaces of the
two products are identical; information in this User’s Guide
applies to both products.

Image Resolution

LitePro 720

The SVGA resolution of the 720’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com­pressed to 800x600. The 720 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 720.

LitePro 730

The XGA resolution of the 730’s projected image is 1024x768.
Screen resolutions between 1024x768 and 1280x1024 are com­pressed to 1024x768. The 730 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
the 730.

NOTE: The 720 automatically
expands 640x480 images to
800x600. Yo u can display these
images at 640x480 by turning off
the Auto Resize feature. See “Auto
Resize” on page 35 for more infor­mation.

NOTE: The 730 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”
on page 35 for more information.

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.

•

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 us e.

•

Transport the projector in a vendor - appr oved hard or soft case.
Part numbers for these cases are listed on page 53. Call your In
Focus dealer to order.

details of the warranty are printed at the back of this manual.
Longer term warranties can be purchased from your In Focus
dealer. Refer to page 54 for part numbers.

SETTING UP THE PROJECTOR

1 Place the projector on a flat surface.

•

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
LitePro 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 54.

2 Position 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 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 60.

NOTE: An optional extension
cable, sold separately, lets you
increase the distance between the
projector and your computer to
70 feet (21 m). See “Accessories”
on page 53.

3 Make sure the projector and your computer are turned off.
