Introduction

The 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:

pYou can connect it simultaneously to two image sources: one PC or Apple Macintosh computer plus one video source, such as a VCR or camcorder.

pYou 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.

1

pIt 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.

pIts 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.

pYou can select front, rear, or ceiling projection, according to the specific needs of your presentation.

pThe 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.

pYou 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.

pThe 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.

pThe 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.

Setting Up the Projector

This 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:

pConnect 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

pConnect 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.

pConnect 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:

Projector

Remote control

2 AA batteries

Power cord

Additional Components

Depending on how you plan to use the projector, you may need these additional components:

pFor complete control of the projector from your computer or to program enhanced special effects on the remote control, you need the optional ELP Link III kit. You can purchase the kit from

your dealer or by calling EPSON Accessories at [phone] (U.S. sales only).

14	1 • Setting Up the Projector

pTo receive an S-Video signal, you will need an S-Video cable. (One is usually provided with your video device.) A separate cable is required for each video source.

pTo connect the projector to a Macintosh PowerBook, you may need a video-out cable and an adapter. (The video-out cable is provided by—or can be purchased from—Apple Computer for all PowerBooks that have video-out capability and require the cable. If your PowerBook doesn’t include one, see your Macintosh dealer. Additionally, some PowerBooks come with an adapter for a high-density, 15-pin, VGA connector.)

pTo connect the projector to an external sound system, you need an RCA-to-3.5 mm stereo audio cable. You can obtain one from your computer dealer.

pTo use the remote control when the projector is not in line-of-sight of the remote, you need an optional infrared repeater. For more information, call [phone] or visit this web address: www.xantech.com.

pTo connect a serial mouse cable to your computer, you may require a special connector, cable, or other components. You can obtain these items from your computer dealer.

pTo protect your projector, you can connect a Kensington MicroSaver® anti-theft device in the hole on the back of the projector. Contact your local computer dealer.

When replacing batteries, take the following precautions: p Don’t mix old and new batteries.

pReplace 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.

pRemove 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:

pPlace 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.

pBecause 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.)

You can connect the projector to two video sources simultaneously (for example, a computer and a VCR), and you can connect a separate audio source for each video source.

If you will be using the optional ELP Link III software, you’ll also need to connect the ELP Link III cables. See Chapter 4 for instructions after you finish connecting the projector to your computer.

Note: If you want to use the remote as a mouse and your computer doesn’t have a PS/2 mouse connector, you must use the ELP Link III kit to connect the projector to a computer.
