SAFETY SUMMARY
Please read these instructions carefully before using your projec-
tor. 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 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 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.

iv
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 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 projector
case, you will void the warranty.
Do Not Disassemble
All projector service must be performed by an authorized In
Focus service center. The only user-serviceable part in the projec-
tor 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 prob-
lem yourself.

INTRODUCTION
The In Focus®LP™ 725 and 730 lightweight multimedia projec-
tors 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 725 has SVGA
800x600 graphics, the 730 has XGA 1024x768 graphics. The user
interfaces of the two products are identical; information in this
User’s Guide applies to both products.
NOTE: 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 infor-
mation.
Image Resolution
LP 725
The SVGA resolution of the 725’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com-
pressed 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 730
NOTE: The 730 automatically
expands 640x480 and 800x600
images to 1024x768. You can dis-
play these images at their original
resolutions by turning off the Auto
Resize feature. See “Auto Resize”
on page 35 for more information.
The XGA resolution of the 730’s projected image is 1024x768.
Screen resolutions between 1024x768 and 1280x1024 are com-
pressed 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.

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 projector 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.
•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 52. 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 “Optional
Accessories” on page 52.
•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 Ceil-
ing Mount Kit is sold separately; see page 52.
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 58.
3Make sure the projector and your computer are turned off.

Setting up the Projector
Connecting the CableWizard™ to the Projector
CAUTION: Turn off the
computer, monitor and projector
whenever you connect or
disconnect cables.
The CableWizard simplifies the connection process by providing
a central hub for all the connections between the projector and
your computer. The connectors on the CableWizard are labeled
with icons.
Connect the end of the CableWizard cable to the
connector on the projector’s connector panel (Figure 5).
NOTE: The projectors are
optimized for use with
CableWizard II. If you have
CableWizards from other models
of In Focus projectors, we do not
recommend using them. Image
quality is reduced by using a
CableWizard other than Cable
Wizard II. The label on the bottom
reads CableWizard or
CableWizard II.
FIGURE 5

Setting up the Projector
Preparing to Connect Your Equipment to the Projector
NOTE: Before you continue,
make sure the projector and your
equipment are turned off. If you’re
connecting a computer, make sure
the distance between it and the
projector is 10 feet or less and
you’ve selected the appropriate
connectors on the CableWizard.
Now you’re ready to connect your equipment. Computers are
connected to the CableWizard. Video players and other equip-
ment, such as external speakers, are connected directly to the pro-
jector.
Steps for connecting the different types of equipment are given
on the pages listed below.
NOTE: In some older computers,
the monitor connector does not
have a hole for Pin 9. If you have
trouble connecting the
CableWizard computer cable to
your computer, contact In Focus
Technical Support.
