Important Operating Considerations for Safety
•
Refer all service to qualified service personnel. Servicing your own projector
can be dangerous to you and will void the warranty.
•
Refer to this guide for proper startup and shutdown procedures.
•
Follow all warnings and cautions in this manual and on the projector.
•
•
Place the projector in a horizontal position no greater than 15 degrees off
axis.
Only use replacement parts specified by InFocus. Unauthorized substitutions
may result in fire, electrical shock, or injury, and may void the warranty
•
•
Locate the projector at least 4' (1.2m) away from any heating or cooling
vents.
Only genuine InFocus lamps are tested for use in this projector. Use of non
InFocus lamps may cause electrical shock and fire, and may void the projector
warranty.
•
Do not block ventilation openings. Locate the projector in a well-ventilated
area without obstructions to intake or exhaust vents. Do not place the
projector on a tablecloth or other soft covering that may block the vents.
•
Hg – Lamp contains mercury. Manage in accordance with local
disposal laws. See www.lamprecycle.org.
•
The projector uses a high-pressure mercury glass lamp. The lamp may fail
prematurely, or it may rupture with a popping sound if jolted, scratched, or
handled while hot. The risk of lamp failure or rupture also increases as the
lamp age increases; please replace the lamp when you see the “Replace Lamp”
message.
•
In the unlikely event of a lamp rupture, particles may exit through the
projector vents. Keep people, food, and drinks out of the "keep out" area
under and around the projector, as indicated by the "X" areas below.
•
Do not place the projector in direct sunlight, humid, greasy or dusty places or
in places where the projector may come into contact with smoke or steam.
•
•
Do not touch or block the projector lens with any objects as this can damage
the projector lens. Scratches, gouges and other lens damage are not covered
by the product warranty.
Do not look directly into the lens while the projector is being used.
•
Do not drop the projector.
•
Do not spill liquid on the projector. Spilled liquid may damage the projector.
•
Use the power cord provided. Connect the power cord to a receptacle with
a protective safety (earth) ground terminal. A surge-protected power strip is
recommended.
•
Do not overload wall outlets.
•
When disconnecting the power cord, hold the plug, not the cord.
•
Wash hands after handling the cables supplied with this product.
•
The projector remote control uses batteries. Make sure the batteries’
polarity (+/-) is aligned correctly. Dispose of used batteries in accordance
with local disposal laws.
•
Use an InFocus approved ceiling mount kit for proper fitting, ventilation and
installation. The warranty does not cover any damage caused by use of nonapproved ceiling mount kits or by installing in an improper location.
•
When the projector is ceiling mounted, wear protective eyewear to prevent
eye injury before opening lamp door.

Follow these instructions to help ensure image quality and lamp life over the
life of the projector. Failure to follow these instructions may affect the
warranty. For complete details of the warranty, see the Warranty/Safety
booklet.

Positioning the projector
Table 1: IN3924 (XGA) Screen size
To determine where to position the projector, consider the size and shape of your
screen, the location of your power outlets, and the distance between the
projector and the rest of your equipment. Here are some general guidelines:
Diagonal Screen Size
(inches/m)

Position the projector on a flat surface at a right angle to the screen. IN3924
must be at least 45” (1.0m) from the projection screen, and IN3926 must be
at least 51” (1.3m) from the projection screen.
If you are installing the projector on the ceiling, we strongly recommend using
InFocus approved ceiling mounts for proper fitting, ventilation and installation.
Refer to the installation guide that comes with the InFocus Ceiling Mount Kit
(p/n PRJ-MNT-UNIV) for more information. The warranty does not cover
any damage caused by use of non-approved ceiling mount kits or by installing
in an improper location. To turn the image upside down, see “Ceiling mount”
on page 28. We recommend using an InFocus authorized ceiling mount.
Position the projector the desired distance from the screen. The distance
from the lens of the projector to the screen and the video format determine
the size of the projected image.
The image offset for IN3924 is 115% +/-5%. This means that if you have an
image 60 inches (1.5 meters) tall from a table-mounted projector, the bottom
of the image will be 9 inches (22.9 cm) above the centerline of the lens. The
image offset for IN3926 is 113% +/-5%. This means that if you have an image
60 inches (1.5 meters) tall from a table-mounted projector, the bottom of the
image will be 7.8 inches (19.8 cm) above the centerline of the lens.

Connecting a computer source
connect VGA cable
VGA connection
Connect one end of the provided computer cable to the Computer 1/Computer 2
connector on the projector and the other to the VGA connector on your
computer. If you are using a desktop computer, you will need to disconnect the
monitor cable from the computer’s video port first.
HDMI connection
connect HDMI
HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI
provides an interface between sources, such as set-top boxes, DVD players, and
receivers and your projector. Plug an HDMI cable into the video-out connector on
the video device and into the HDMI connector on the projector.
Connecting power
connect power
Connect the black power cord to the Power connector on the rear of the
projector and to your electrical outlet. If the Power Saving Mode feature is off, the
Power LED on the Status Indicator Panel (page 12) blinks orange. If the Power
Saving Mode feature is on, the Power LED is steady orange. By default, this feature
is off. You can change the setting, see page 29.. NOTE: Always use the power cord
that shipped with the projector.
connect audio cable
Optional computer connections
To get sound from the projector, connect an audio cable (optional cable, not
included) to your computer and to the Audio in connector on the projector. You
may also need an adapter.
If you are using a desktop computer and want to see the image on your computer
screen as well as on the projection screen, connect to the desktop’s computer
cable to Computer 1 and the desktop’s monitor cable to the Monitor out
connector on the projector.
Displaying an image
press Power button
Press the Power button.
The Power LED lights orange, and the fans start to run. When the lamp comes on,
the start up screen displays. It can take up to a minute for the image to achieve full
brightness.
No start up screen? Get help on page 13.
Turn on your computer or video device.
turn on computer or
video device
The image should appear on the projection screen. If it doesn’t, press the Source
button on the projector’s keypad or remote.
If you are using a VGA cable to connect your computer to the projector:
If using a laptop, make sure its external video port is active.
Many laptops do not automatically turn on their external video port when a
projector is connected. Usually a key combination like FN + F8 or CRT/LCD key
turns the external display on and off. Locate a function key labeled CRT/LCD or a
function key with a monitor symbol. Press FN and the labeled function key
simultaneously.
activate laptop’s external port
