Setting Up the Projector
This chapter describes how to unpack your projector, connect it to 
other equipment, and turn everything on. The projector must be 
connected to a computer or a video source such as a VCR, camcorder, 
digital camera, or laser disc player before it can project any images. 
You may also want to set up the projector for one or more of the 
following:
❐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, you 
use the remote control’s pointer to control the screen cursor.
❐Provide audio for one or both image sources. The audio source can 
be the computer, video source, or another device such as a stereo.
❐Connect to an external speaker or PA system to amplify the audio.

❐Projector Software CD ROM
You will not need all these components; your configuration will 
determine which ones you need.
Save all packaging in case you need to ship the projector in the future. 
Always transport the projector in its original packaging (or the 
equivalent), or use a carrying case if you are carrying the projector by 
hand. (See page 141 for instructions.)
Additional Components
Depending on how you plan to use the projector, you may need 
additional components:
❐To receive an S-Video signal, you need an S-Video cable. (One is 
usually provided with your video device.) A separate cable is 
required for each video source.
❐To connect a second computer, you need a computer video and 
audio cable.

❐To connect the projector to a Macintosh PowerBook, you may 
need a video-out cable. (One is provided by—or can be purchased 
from—Apple for all new PowerBooks that have video-out 
capability.) If your PowerBook does not include one, see your 
Macintosh dealer.
❐You can not currently use the ELP Link IV software with a Power 
Macintosh G3 or iMac. Check with your dealer for future support.
❐To 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.
❐To connect the mouse cable to your computer, you may require a 
special connector, cable, or other components. You can obtain 
these items from your computer dealer. 
Note: You can connect a Kensington MicroSaver
® anti-theft device in 
the hole on the projector’s right side. Contact your computer dealer.

Installing the Remote Control Batteries
You can use the remote control as a wireless mouse instead of your 
computer’s mouse to control your presentation. You can also use it to 
control the projector menus and use the Effects buttons. 
Follow these steps to install the batteries in the remote control:
1. Slide off the battery compartment cover.
2. Insert the two AA batteries included with the projector. Make sure 
the polarity of the batteries is correct.

3. Replace the battery compartment cover.
When replacing batteries, take the following precautions:
❐Do not mix old and new batteries.
❐Replace 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.
❐Remove batteries if you will not be using the projector for a long 
period of time.
Before You Connect the Projector
Before you start connecting the projector to your equipment, decide 
where you will want to place your projector and computer or video 
source. The distance between the projector and the screen determines 
the actual image size. Place the projector somewhere between 4 and 
54.7 feet (1.2 and 16.7 meters) away from the screen; use the general 
guidelines in the table below to determine the proper distance. (For 
more precise calculations, see “Positioning the Projector” on page 62.) 
Caution: Do not hold or lift the projector by the lens. This can damage the 
lens.

Be sure to place the projector on a sturdy, level surface within five feet 
of the computer or video source.
