Setting Up the Projector

This chapter tells you how to set up the projector and connect it to a

laptop computer or video source. If you need to connect the projector to a desktop or workstation computer, see Appendix A.

You’ll find instructions for the following in this chapter:

■ Positioning the projector

■ Connecting to a laptop computer

■ Connecting to video sources

Setting Up the Projector 9

caution

p y

Don’t hold or lift the

rojector by the lens, or

ou may damage it.

note

It’s easier to position the

rojector when the screen is directly in front of the room. If the screen is placed diagonally in a corner, it’s much more difficult to aim the projector correctly at the screen and get a rectangular image.

Positioning the Projector

Before connecting the projector, you need to decide where to place it. The location you choose depends on the size of the room and what you are projecting.

■ Place the projector on a sturdy, level surface, between

3.2 and 38.5 feet from the screen.

■ Make sure there is plenty of space for ventilation around and

under the projector.

■ Make sure the projector is within 6 feet of an electrical outlet or

extension cord and within 5 feet of your computer and/or video source.

■ Place the projector directly in front of the center of the screen,

facing the screen squarely. Otherwise, your image will not be rectangular.

Most presenters find it convenient to place the projector in front of the audience, leaving as much space as possible between the projector and the screen to get a good-sized image. This lets the presenter stand in the front of the room, face the audience, and remain close enough to the equipment to be able to control it.

Use the figure below as a guideline to help you determine how far from the screen to place the projector. Image size generally increases with distance, but may vary depending on how you position the zoom ring and whether you have adjusted the image size with other settings.

10 Setting Up the Projector

33.2 to 38.5 feet 6.5 to 7.5 feet 3.2 to 3.7 feet

If you place the projector below the level of the screen, you’ll have to

A p

p p

tilt it up by extending the feet as shown. Tilting the projector upward causes the image to lose its rectangular shape, but the Auto Keystone feature corrects the distortion automatically. If the image does not regain its rectangular shape, the Auto Keystone feature may have been disabled. To turn it on or for more information on keystone correction refer to the next chapter.

If you place the projector level with the bottom of the screen, the image will be rectangular and you won’t have to adjust it. If you place the projector higher than the bottom of the screen, the image will still be rectangular, but you won’t be able to fill the whole screen with the image.

note

fter positioning the

rojector, you may want to

connect a Kensington

icroSaver anti-theft device

to the lock port on the

rojector’s left side. You can urchase this from EPSON;

see page 7.

Setting Up the Projector 11

Connecting to a Laptop Computer

note

To connect to desktops and other computer systems, see

ppendix A. If you have an iBook with an RCA videoout port, follow the instructions for connecting to a video device on page 16.

You can connect the PowerLite projector to any computer that has a standard video output (monitor) port, including PC notebook and laptop computers, Macintosh PowerBooks and iBooks, and hand-held devices.

Connecting the Computer Cable

Before you start, make sure your computer and the projector are turned off.

1. Connect one end of the computer cable to the projector’s

Computer/Component Video port.

note

Laptop configurations vary. See your computer manual

or the location of the ports

needed to connect your

rojector.

12 Setting Up the Projector

2. Connect the other end of the computer cable to your laptop’s video-out or monitor port.

If you’re using a PowerBook or iBook and you can’t connect the cable, you may need to use the Macintosh desktop adapter as shown on page 79 (available from EPSON; see page 7).

3. Tighten the screws on the connectors.

If you don’t need to make any other connections, you can plug in your projector and turn it on. See page 20 for instructions.

Connecting the Cable for Remote Mouse Control

Using the remote control as a wireless mouse lets you click through slideshow-style presentations, such as PowerPoint, from up to 20 feet away (for details, see page 34). This gives you more flexibility in delivering your presentation, since you won’t need to stand near your computer.

1. Locate the USB mouse cable and connect one end of the cable to the projector’s USB port.

2. Connect the other end of the cable to the external mouse port or USB port on your laptop, as shown.

3. If necessary, configure your laptop to work with an external mouse.

If you don’t need to make any other connections, you can plug in your projector and turn it on. See page 20 for instructions.

Setting Up the Projector 13

Amplifying Computer Audio

Your laptop probably has its own sound system; however, it may not be adequate for your presentation. If you need more volume, you can connect a computer audio cable to take advantage of the projector’s built-in amplifier and speaker. You can obtain a computer audio cable (3.5-mm stereo miniplug cable) from a computer or electronics dealer.

1. Connect one end of the audio cable to the

Audio In jack on the

projector.

2. Connect the other end of the audio cable to your laptop’s headphone jack or audio-out jack. (Jack locations vary; see

your computer manual if you’re not sure which jack to use.)

If you don’t need to make any other connections, you can plug in your projector and turn it on. See page 20 for instructions.

14 Setting Up the Projector

Connecting to Video Sources

You can connect a DVD player, VCR, camcorder, laser disc player, gaming consoles, such as Microsoft Xbox, Sony PlayStation 2, and Nintendo GameCube, digital camera, or any other compatible video source to your projector.

The projector supports HDTV, NTSC, PAL, and SECAM, and automatically detects the video format.

The projector can receive composite video, S-Video, and component video. The type of cable you use depends on whether you have composite video, S-Video, or component video.

note

The projector does not support TV antenna cable F connectors.

■ For composite video, use the included RCA AV cable included

with the projector.

■ For component video, you will need the optional EPSON

component video cable (ELPKC19).

■ For S-Video, use the S-Video cable supplied with your video

device or obtain one from you electronics dealer.

Follow the instructions below for your type of connection.

To play audio from your video equipment, you will need a special adapter cable. See your projector dealer to obtain the correct cable.

Setting Up the Projector 15

Connecting the RCA Video Cable

Before starting, make sure the projector and your DVD player or other video source are turned off.

1. Connect one end of the yellow RCA plug to the projector’s

Video

jack.

2. Connect the other end of the plug to the video-out jack on your

video source.

16 Setting Up the Projector

Connecting an S-Video Cable

If your video source has an S-Video jack, you can use it to project a higher quality video image. However, you’ll need an S-Video cable, which may be included with your video source, or may be purchased.

Before starting, make sure the projector and your DVD player or other video source are turned off.

1. Insert one end of an S-Video cable into the projector’s port.

2. Insert the other end into the S-Video output port of your video source.
