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:

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 solutions:

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.

iii

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 compact, lightweight projector that lets you project SVGA (PowerLite 5500C) or XGA (PowerLite 7500C) full-color images and video onto a large screen for presentations. 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. You can also connect audio for each image source.

Images are displayed in SVGA at a resolution of 800 × 600 pixels (PowerLite 5500C) or XGA at a resolution of 1024 × 768 pixels (PowerLite 7500C). Your projector produces bright images that can be easily seen in rooms light enough to take notes.

The projector’s 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.

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 can 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 optional ELP Link III software to control the projector’s settings from your computer and reconfigure the projector’s special effects.

Your projector features a new patented SizeWize™ chip for supporting a variety of computer output resolutions. For example, if you have the PowerLite 5500C, the resize feature lets you display VGA or XGA images at the projector’s SVGA resolution. On the PowerLite 7500C, you can resize the image to display VGA, SVGA, or SXGA images at the projector’s XGA resolution. No matter what type of computer output is used, the result is a full-size video image of outstanding clarity.

Your projector supports IBM® compatible PCs and laptops, as well as Apple Macintosh, Power Macintosh™, and PowerBook™ computers. The video source can be NTSC, PAL, or SECAM. The projector automatically senses the video format, which can be composite video or S-Video. See Chapter 7 for details on supported computers and video formats.

2 Introduction

Getting the Most Out of Your Projector

Your projector comes with a full set of features that allow you to control the settings for the image display, video, and audio. Read this section for a quick summary of the important features.

Remote Control

The buttons on the remote control let you turn the projector on and off, and provide direct access to blank, freeze, volume, mute, and image source switching. Use the remote control buttons to access custom functions with the optional ELP Link III software and the projector’s menu system. You can even use the remote control in place of your computer’s mouse.

Sleep Mode

Sleep mode conserves electricity by automatically turning off the lamp after the projector has not been used for 30 minutes. In sleep mode, the projector remains on but the lamp is turned off, conserving electricity, cooling the projector, and extending the life of the lamp.

Control Panel

The control panel buttons on the projector duplicate the remote control buttons and let you perform additional functions, such as adjusting the tracking and sync for computer images.

Where to Get Help

Installation

This chapter describes how to unpack and set up your projector, and connect it to other equipment. The projector must be connected to a computer or a video source such as a VCR, camcorder, or laser disc player before it can project any images. You may also want to:

●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.

●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.

●Connect the projector to an external speaker to amplify the audio.

Unpacking the Projector

When you unpack the projector, make sure you have all these components:

Before You Connect the Projector

Before you begin, decide where you want to place the projector and computer or video source. Be sure to place the projector on a sturdy, level surface within five feet of the computer or video source. The distance between the projector and the screen determines the image size. Place the projector between 2.4 and 53.7 feet (0.8 and 16.4 meters) away from the screen; use the table below to determine the proper distance. (For more precise calculations, see page 45.)

Caution: Do not hold or lift the projector by the lens; this can damage the lens.
