SAFETY SUMMARY
Please read these instructions carefully before using your
LitePro 720 or 730. 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 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 look 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 con-
ductors 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.

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 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 pro-
jector is turned off and the lamp has cooled for at least 2 minutes.
Follow the instructions in this manual for lamp replacement care-
fully.
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.
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 LitePro
case, you will void the warranty.
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
Technical Support, you may want to refer to “Troubleshooting”
starting on page 45 to see if you can resolve the problem yourself.

INTRODUCTION
The In Focus LitePro®720 and 730 lightweight multimedia pro-
jectors combine powerful and sophisticated features with easy-
to-use, 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 appli-
cations 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.
NOTE: The 720 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 infor-
mation.

Usage Guidelines
•Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.
NOTE: If the LitePro overheats
and turns off, you must wait about
30 seconds before you attempt to
turn it back on.
•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 use.
•Transport the projector in a vendor-approved hard or soft case.
Part numbers for these cases are listed on page 53. Call your In
Focus dealer to order.

SETTING UP THE PROJECTOR
1Place 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.
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.
•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 Ceil-
ing Mount Kit is sold separately; see page 54.
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 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.
3Make sure the projector and your computer are turned off.
