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.

If the remote control still does not work properly, remember you can always control your computer-based

Introduction

he EPSON® projector that lets you project full-color images and video onto a large screen for presentations. It supports IBM laptops, as well as Apple PowerBook

The projector also supports a wide range of video formats.

Note:

See page 153 for details on supported computers and video formats.

In addition to its size and versatility, your projector offers the following advantages:

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 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.

PowerLite® projector is a compact, lightweight

compatible PCs and

computers.

Macintosh,®

Power Macintosh,™

and

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.

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.

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

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.

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.

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.

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.

Introduction

Safety Instructions

Always follow these safety instructions:

1. Place the projector on a flat, stable surface.

2. Don’t use the projector near water or sources of heat. Don’t

place the projector or remote control on top of heat-producing equipment, and avoid places subject to shocks and vibrations, or high or rapidly changing temperatures and humidity.

3. Use attachments only as recommended.

4. Use the type of power source indicated on the projector. If

you’re not sure of the power available, consult your dealer or power company.

5. Place the projector near a wall outlet where you can easily

unplug it.

Placez le projecteur près d’une prise de contacte où la fiche peut être débranchée facilement.

6. Insert the projector’s three-wire grounding-type plug into a

properly grounded outlet. If you have a two-prong outlet, contact an electrician to replace it. Don’t touch the plug with wet hands, as this can cause electric shock.

7. Always insert the plug firmly into the outlet. Also, avoid dusty

outlets. Failure to follow these precautions could result in fire.

8. Don’t overload wall outlets, extension cords, or integral

convenience receptacles. This can cause fire or electric shock.

Safety Instructions

9. Don’t place the projector where the cord can be walked on, which can result in fraying or damage to the plug.

10. Unplug the projector from the wall outlet before cleaning. Use a damp cloth for cleaning. Don’t use liquid or aerosol cleaners.

11. Don’t block the slots and openings in the projector case. They provide ventilation and prevent the projector from overheating. Don’t operate the projector on a sofa, rug, or other soft surface, or in a closed-in cabinet unless proper ventilation is provided.

12. Never push objects of any kind through cabinet slots. Never spill liquid of any kind into the projector.

13. Except as specifically explained in this User’s Guide, don’t attempt to service the projector yourself. Refer all servicing to qualified service personnel. Opening or removing covers may expose you to dangerous voltages and other hazards.

14. Unplug the projector during electrical storms, or when it will not be used for extended periods.

15. Unplug the projector from the wall outlet and refer servicing to qualified service personnel under the following conditions:

When the power cord or plug is damaged or frayed

Introduction

Setting Up the Projector

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:

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.

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 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

Before you start connecting cables, decide where you want to place the projector and computer or video source. Follow these guidelines:

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.

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.)

Where to Place the Projector

In addition to front projection, your projector supports rear

Connecting to a Video Source Other Than a Computer

In addition to your computer, you can connect a VCR, camcorder, DVD player, or any other compatible video source to your projector.

If you want, you can connect a single video source, such as a VCR. You don’t have to connect a computer unless you want to use the optional ELP Link III software. You can also connect a computer plus a second video source simultaneously. If your video source has audio capability, it can also be an audio source.

The projector can receive composite video or S-Video:

If your video device has a one-pin RCA video jack, it’s a composite video source. Use the audio/video (A/V) cable supplied with the projector to connect the projector to your video device.

If your video device has a four-pin video jack, it’s an S-Video source. To connect the video device to your projector, use the S-Video cable supplied with your video device, or obtain an S-Video cable from your computer dealer.

The projector is not compatible with a cable TV-style F

Note:

connector.

If both a composite video and S-Video device are connected to the projector, the projector automatically selects S-Video as the default video source. To display composite video, disconnect the S-Video device.

Connecting to a Video Source Other Than a Computer

The projector supports NTSC, PAL, PAL60, and SECAM video formats, and automatically detects and identifies the video format. However, if automatic selection is not possible for some reason, you can specify that a specific video format be detected (see page 74).

If you change the Video Signal setting in the Setting menu to

Note:

specify a particular video format, the projector will be able to detect only the format specified. To have the projector automatically detect any supported video format, reset the Video Signal setting to Auto.

Follow these steps to connect a video device:

1. Turn off the projector and video device, if they’re on.

2. Locate the appropriate video cable:

If your video source has a large, round, four-prong S-Video connector, use the cable that came with your video device, or purchase an S-Video cable from your computer dealer.

If your video source has a small, round, one-prong composite (RCA) video connector, use the audio/video (A/V) cable that came with the projector. (The A/V cable has three RCA plugs on either end of the cable.)

1 • Setting Up the Projector

3. For S-Video, insert one end of an S-Video cable into the projector’s S-Video In connector. Insert the other end into the S-Video Out jack on your video device.

2. Audio source (if different from the computer or video source)

3. External amplified speaker or PA system (if you’ve connected one)

4. Projector (see instructions below)

5. Computer

When you’re ready to turn off the equipment, do so in the reverse order.

Turning the Projector On and Off

Before you turn on the projector, make sure it is plugged in and connected to your video source.

1. Remove the projector lens cap.

2. Turn on the main power switch located at the rear of the projector and wait until the power light turns orange.

Turning the Equipment On and Off

3. Press the Power button on the remote control or the control panel on top of the projector. The power light flashes green as the projector warms up. When the projector is fully warmed up, this light remains green.

If computer or video equipment is attached, the computer or video signal is projected. Allow about 30 seconds for full illumination.

Warning:

Never look into the lens when the lamp is on. This can damage your eyes. It is especially important that children not look into the lens.

When you want to stop projecting images, press the Power button again. The fan remains on and the power light flashes orange for about two minutes as the projector cools down.

Note:

while the power light is orange, there may be a delay before a projected image appears.

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’s power light turns a steady orange and only a minimum amount of the projector’s circuitry remains on. This conserves electricity, cools the projector, and extends the life of the lamp.

When the projector is in sleep mode, press the Power button to resume projecting images, or press the power switch on the back of the projector to turn it off.
