Connecting to an Audio Source
The projector has two inputs for audio: one for your computer and one for your
video source. Each input has two audio jacks: the L jack controls the left speaker
and the R jack controls the right speaker. If you’re connecting to an audio
source that has only a single plug, connect it to the L Audio In jack.
To receive audio from the computer or video source, use the video/audio cable
supplied with the projector. To receive audio from both the computer and video
source, you need to obtain an additional cable from your computer dealer. 
1. Connect one end of the audio cable to the appropriate (computer or video
source) Audio In jacks on the projector. Insert the white plug in the L Audio
In jack and the red plug in the R Audio In jack. (You don’t use the yellow
plug unless you’re supplying composite video.)
2. Connect the other end of the cable to the audio source. Insert the white plug
in the L Audio Out jack, and the red plug in the R Audio Out jack.

							14 1  •  InstallationConnecting to an External Speaker or PA System
For most small- or medium-sized rooms, the projector’s internal speakers are
sufficient. If you need extra amplification for a large room, you can connect the
projector to an external amplified speaker or PA system.
To connect the projector to an external sound system, you need to obtain an RCA-
to-3.5mm Stereo audio cable. You can get one from your computer dealer.
Before beginning, turn off the projector and the speaker or PA system.
1. Connect the cable’s 3.5mm stereo miniplug into the projector’s Audio Out
jack.
2. Connect the RCA plug to the external amplified speaker or PA system. Insert
the cable’s red plug into the R side, and the white plug into the L side.
You should now adjust the Fade menu setting. See page 39.

Setting Up Serial Communication
The RS-232C Serial Communication Kit allows your computer and projector
to communicate so you can access the projector menus from your computer
and use the remote control to control your computer. The kit consists of a
cable, a Macintosh adapter, and two software utilities: ELP Link and ELP
Remote Programmer.
Instructions for installing the cable and software are given in the next two
sections. For information on using ELP Link, see Chapters 2 and 3. For
information on the ELP Remote Programmer, see Chapter 4.
By default, the Serial setting in the Options menu is on to enable communication
when the Serial Communication Kit is installed. If, after installing the kit, you
cannot enable communication, make sure the Serial setting has not been turned
off. See Chapter 3 for more information about the menus.
Connecting the serial cable
To connect the serial RS-232C cable to your computer and projector:
1. Connect one end of the serial RS-232C cable to the projector’s RS-232C
connector.
2. If you have a Macintosh, attach the RS-232C adapter to the modem port on
the Macintosh.

The modem port is identified by the following icon:
                                             
3. Connect the other end of the RS-232C cable to the PC’s RS-232C serial
connector or to the RS-232C adapter on your Macintosh. The serial
connector on your PC is a nine-pin male connector. It may be labeled Serial,
RS-232C, COM1, or something similar. If you have a 25-pin serial connector,
you need to obtain a 25-pin to 9-pin converter.
Installing the software
Two diskettes are provided with the kit: one for the Macintosh and one for the PC.
Use only the diskette appropriate for your platform. Each contains ELP Link and
the ELP Remote Programmer.
Before installing the software, exit any open programs. Insert the appropriate
diskette in a diskette drive. Then do the following:
• Windows.
®  For version 3.1, in the Program Manager, choose Run from the
File menu; for Windows 95, choose Start and then Run. In the Command Line
text box, type A:SETUP or B:SETUP as appropriate. Choose OK. Then
follow the onscreen instructions.
• Macintosh. Double-click on the ELP Installer icon and follow the onscreen
instructions.

Connecting the Remote Control with the Lead Wire
If you set up the projector for rear projection and want to use the remote control
to control the projector, you need to connect the remote control directly to the
projector with the optional lead wire. You might also need to directly connect
the remote control if anything is blocking the path between the remote control
and the projector.
To directly connect the remote control, connect one end of the lead wire to the
projector’s Remote jack. Connect the other end to the output terminal at the front
end of the remote control. Make sure both ends are plugged in securely.

2Using the Projector
T
his chapter provides the following information about using your projector:
• Turning the equipment on and off
• Focusing and positioning the image
• Controlling the projector with the remote control, operation panel, and ELP
Link software
• Monitoring the status of the projector
• Using rear projection. 
						

							20 2  •  Using the ProjectorTurning the Equipment On and Off
Always turn on the projector and its attached equipment in the following order:
1. Monitor
2. Video source
3. Audio source (if different than computer or video source)
4. Projector
5. External amplified speaker or PA system
6. Computer.
The projector’s power switch is at the back. When you turn on the projector, the
green power indicator comes on and the lamp begins to warm up. Remove the
lens cap. After a few seconds, an image appears on screen.
u
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.
If the lamp does not come on when you turn on the projector, the projector may
be in standby mode. To turn off standby mode, press the Standby button on the
remote control. 
To turn off the projector and other equipment, reverse the order shown above.
After you turn off the projector, the fan may remain on a few minutes to dissipate
heat from the lamp. Always wait 10 to 60 seconds before turning the projector
back on. If you turn on the projector immediately after turning it off, the lamp
might be too hot and the projector will not turn on.

Focusing and Positioning the Screen Image
When an image appears on screen, check that it is in focus and correctly
positioned on the screen. To focus the image, rotate the focus ring, which is the
outside ring on the lens. To adjust the size of the image, rotate the zoom ring,
which is the inside ring. Rotate the zoom ring clockwise to make the screen
image larger or counterclockwise to make it smaller.
