Important Information About Your Projector
Important Safety Information
Warning: Never look into the projector lens when the lamp is turned on; the bright light can damage your
eyes. Never let children look into the lens when it is on. Never open any cover on the projector, except the
lamp and filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as
specifically explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing
to qualified service personnel.
Warning: The projector and its accessories come packaged in plastic bags. Keep plastic bags away from
small children to avoid any risk of suffocation.
Caution: When you replace the lamp, never touch the new lamp with your bare hands; the invisible residue
left by the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.
Remote Control Information
You can operate the projector by remote control via a line-of-sight infrared (IR) receiver at the front of the
projector. The projector may not respond to remote control commands under the following conditions:
p
There is an object between the remote control IR emitter and the IR receiver on the projector.
p
Ambient light is too bright.
p
Certain types of fluorescent lighting are used.
p
A strong light source shines into the IR receiver.
p
Other equipment that emits infrared energy, such as a radiant room heater, is in the room.
These conditions commonly cause problems for most infrared-controlled equipment. Try the following
solutions:
p
The remote control unit’s batteries may be low on power; replace them.
p
Dim the ambient lighting and/or turn off any fluorescent lights.
p
Close any window coverings and/or move the projector out of direct sunlight.
p
Turn off other equipment that emits infrared energy.
If the remote control still does not work properly, remember you can always control your computer-based
iii
presentation directly from the computer, even in an environment containing one of the conditions listed above.

Setting Up the Projector
T
his chapter describes how to unpack the projector, connect it to
other equipment, and turn it on.
Before it can project any images, the projector must be connected to
a video source, such as a computer, VCR, camcorder, or DVD
player. If you want, you can connect your projector to both a
computer and a second video source. You can also do any of the
following:
p
Connect the projector to an audio source for one or both video
sources. The audio source can be the computer, a video device
capable of producing audio (such as a VCR or camcorder), or
another device such as a stereo.
11
p
Connect the mouse cable to use the remote control as a wireless
mouse. Except for some laptops, this disables your computer’s
mouse. If you are also viewing the display on your monitor, the
remote control’s pointer controls the screen cursor.
p
Connect the projector to an external speaker or public address
(PA) system to amplify the audio.
Unpacking the Projector
When you unpack the projector, make sure you have all these
components:

Installing the Remote Control Batteries
You can use the remote control as a wireless mouse instead of your
computer’s mouse to control your presentation. If you purchased the
optional ELP Link III kit, you can assign different functions to the
Effects buttons, and even program the buttons with your own
customized functions. (See “Assigning Functions to the Effects
Buttons” on page 102.) Follow these steps to install the batteries:
1. Slide off the battery compartment cover
.
2. Insert the two AA batteries included with the projector. Make
sure the polarity of the batteries is correct.

3. Replace the battery compartment cover.
When replacing batteries, take the following precautions:
p
Don’t mix old and new batteries.
p
Replace batteries as soon as they run out. If the batteries leak,
wipe away battery fluid with a soft cloth. If fluid gets on your
hands, wash them immediately.
p
Remove the batteries if you plan not to use the projector for a
long period of time.
Where to Place the Projector
Before you start connecting cables, decide where you want to place
the projector and computer or video source. Follow these
guidelines:
p
Place the projector on a sturdy, level surface within five feet of
your computer or video source. Remember not to place the
projector near sources of heat, or in a location where the cord is
likely to be stepped on.
p
Because the distance between the projector and screen
determines image size, position the projector the proper distance
from the screen for the size image you want to project. Use the
following table to determine the correct distance. (For more
precise calculations, see page 52.)
