Important Information About Your ProjectorImportant Safety InformationWarning: 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 InformationYou 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  
						

							 
         ivpresentation directly from the computer, even in an environment containing one of the conditions listed above.

Introduction
T
he EPSON
® PowerLite
® projector is a compact, lightweight 
projector that lets you project full-color images and video onto a 
large screen for presentations. It supports IBM
® compatible PCs and 
laptops, as well as Apple
® Macintosh,
® Power Macintosh,
™ and 
PowerBook
® computers. 
Note: The projector also supports a wide range of video formats. 
See page 153 for details on supported computers and video formats.
In addition to its size and versatility, your projector offers the 
following advantages:
p
You can connect it simultaneously to two image sources: one 
PC or Apple Macintosh computer plus one video source, such as 
a VCR or camcorder. 
p
You can connect the projector to an audio source for one or both 
image sources. The audio source can be the computer, video 
source, or another device such as a stereo. 
						

							Introduction  2
p
It produces images that can be easily seen in rooms light enough 
to take notes. The PowerLite 5550C displays images in SVGA 
at a resolution of 800 ×
 600 pixels. The PowerLite 7550C 
displays images in XGA at a resolution of 1024 ×
 768 pixels.
p
Its two speakers employ a built-in SRS 3D Sound System for 
rich, powerful audio output. You can also connect an external 
speaker when further amplification is required.
p
You can select front, rear, or ceiling projection, according to the 
specific needs of your presentation.
p
The projector’s new patented SizeWize
™ chip supports a variety 
of computer output resolutions. For example, the resize feature 
lets you display VGA or XGA images at the projector’s SVGA 
resolution.
p
You can control your projector through a hand-held remote 
control, which can also act as a wireless mouse to control the 
cursor on your computer screen during presentations. 
p
The optional ELP Link III software enables you to control the 
projector from a computer. In addition, it lets you assign 
functions both to your keyboard and to the remote control, and 
even program the keyboard and remote control with your own 
customized functions.
p
The projector’s sleep mode conserves electricity by 
automatically turning off the lamp after the projector has not 
been used for 30 minutes. The projector remains on, but the 
lamp is turned off, cooling the projector and extending the life 
of the lamp.
