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 and rear of 
the projector. The projector may not respond to remote control commands under the following conditions:
❐There is an object between the remote control IR emitter and the IR receiver on the projector.
❐Ambient light is too bright.
❐Certain types of fluorescent lighting are used.
❐A strong light source shines into the IR receiver.
❐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:
❐The remote control unit’s batteries may be low on power; replace them.
❐Dim the ambient lighting and/or turn off any fluorescent lights.
❐Close any window coverings and/or move the projector out of direct sunlight.
❐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 
presentation directly from the computer, even in an environment containing one of the conditions listed above.

Introduction
Your EPSON® PowerLite® projector is a brilliant, lightweight, 
portable projector that allows you to project full-color images and 
video onto a large screen for presentations. You can connect it 
simultaneously to three image sources: two computers or workstation 
sources, plus one video source, such as a VCR, DVD player, 
camcorder, or digital camera. You can also connect audio for each 
image source.
Images are displayed in full color (16,770,000 colors) at an SVGA 
resolution of 800 × 600 pixels on the PowerLite 5350, and an XGA 
resolution of 1024 × 768 pixels on the PowerLite 7250 and 7350. The 
projectors support a wide variety of video inputs, from VGA to UXGA 
with resolutions up to 1600 × 1200. It produces bright images that can 
be easily seen in rooms light enough to take notes.  
						

							Introduction
  2
Your projector’s two speakers employ a built-in SRS 3D Sound System 
for rich, powerful audio output. You can even connect an external 
speaker when further amplification is required.
For your presentations, you can select front, rear, or ceiling projection. 
This provides maximum flexibility in choosing the best display 
method for each environment.
You control your projector through a hand-held remote control unit, 
with menus provided for image source switching and image 
adjustment. The remote control can also act as a wireless mouse to 
control operations on your computer screen during presentations. 
Additionally, you can install the projector’s ELP Link IV software to 
control the projector’s settings from your computer and enhance your 
presentations with special effects.
Your projector features a new patented SizeWise
™ chip for support of 
SVGA, UGA, XGA, and SXGA (PowerLite 5350), and XGA, VGA, 
SXGA and UXGA (PowerLite 7250 and 7350) output. No matter 
what type of computer output is used, the result is a full-size video 
image of outstanding clarity.
The projector supports a wide range of computers and workstations: 
IBM
® compatible PCs and laptops, Apple® Macintosh,®  Power 
Macintosh,™ Power Macintosh G3,™ iMac,™ and PowerBook® 
computers, and workstations such as the Sun® SPARCstation.™ 
(The PowerLite 5350 is not recommended for use with high-end 
workstations). The video source can be HDTV, NTSC, PAL, or 
SECAM. The projector automatically senses the video format, which 
can be composite video, S-Video, or component video. See Chapter 7 
for details on supported computers and video formats.
