Important Operating Cons
iderations for Safety
• 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.
• Locate the projector at least 4 (1.2 m) away from any heating or cooling 
vents.
• 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.
• Do not place the projector in direct sun light, 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. Di spose 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 co ver any damage caused by use of non-
approved 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.
• Refer all service to qualified service personnel. Servicing your own projector can be dangerous to you and will void the warranty.
• Only use replacement parts specified by  InFocus.  Unauthorized substitutions 
may result in fire, electrical shock, or injury, and may void the warranty
• 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. 
• 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 po pping 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. Please keep people, food, and drinks at least 3’ (1m) away 
from all projector vents. For ceiling applications, keep people, food and drinks 
out of the keep out area under and around the projector, as indicated by 
the illustration.

Positioning the projector
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:
• Position the projector on a flat surface  at a right angle to the screen. IN112a/
IN112aT and IN114a/IN114aT must be at least 45.3” (1.2m) from the projection 
screen, IN116a must be at least 55.4” (1.4m) from the projection screen, 
IN114STa must be at least 15” (0.4m)  from the projection screen, IN118HDa 
must be at least 37.5” (1.0m) from the  projection screen, and IN118HDSTa must 
be at least 30.6” (0.78m) from the projection screen.
• If you are installing the projector on th e ceiling, we strongly recommend using 
InFocus approved ceiling mounts for proper fitting, ventilation and installation. 
Refer to the installation guide that come s with the InFocus Ceiling Mount Kit (p/n 
PRJ-MNT-UNIV) for more information. Th e warranty does not cover any damage 
caused by use of non-approved ceiling moun t 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 an d the video format determine the size of 
the projected image.

Connecting a computer source
VGA connection
Connect one end of the provided computer cable to th 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
HDMI is a standard, uncompressed, all- digital audio/video interface. HDMI 
provides an interface between sources, su ch 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.
NOTE: The IN112aT/IN114aT do not have an HDMI connector.
Connecting 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 Stat us Indicator Panel (
page 12) blinks blue. If the Power Saving 
Mode feature is on, the Power LED is steady  blue. 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.
Optional computer connections
To get sound from the projector, connect an audio cable (optional cable, not 
included) to your computer and to th  Audio 1/Audio 2 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

The Power LED lights blue,  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. Note: When the feature, AC Power On, is enabled, the projector 
automatically turns on when power is connected. This allows control of ceiling 
mounted projectors with a wall power switch.

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. 
Refer to your laptops documentation fo r more information about your laptops
