Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speakers, you can use a computer audio cable. The 
required cable (3.5-mm stereo miniplug cable) is available from 
computer or electronics dealers.
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 the speaker or 
audio out port on the computer’s sound card.

Connecting to a Desktop Macintosh 
You can connect the projector to any desktop Macintosh. This section 
includes instructions for the following:

Connecting the computer video cable 

Connecting the mouse cable (if you want to use your remote 
control as a mouse)

Connecting an optional audio cable (if you’ll be projecting with 
audio)
When you connect the projector to a desktop Macintosh, you cannot 
view your display on the Macintosh monitor.
Follow the steps in each section for the cables you need to connect. 
Before beginning, turn off the projector and computer if they are on.
Connecting the Computer Cable
Follow these steps to connect the computer cable. You may not need 
to use the adapter as shown.
1. Disconnect the monitor cable from the video port on the back of 
the Macintosh.
2. Connect one end of the computer cable to the projector’s 
Computer port, as shown. 
 
3. Connect the other end of the computer cable to the video port on 
the Macintosh. 
note
Macintosh configurations 
vary. See your computer 
manual for the location of the 
ports needed to connect your 
projector. Older models may 
require a Macintosh adapter, 
which you may purchase 
from EPSON; see page 8.

adapter (if 
needed) 
						

							78Appendix A: Connecting to Additional EquipmentIf it doesn’t fit, you may have to use a Macintosh desktop adapter, 
which you can buy from EPSON (see page 8). 
To use the adapter, remove its cover as 
shown and set its DIP switches according 
to the resolution you want to use, such as 
16-inch mode. See your Macintosh 
documentation for instructions.
Replace the cover and connect the 
adapter to the free end of the computer 
video cable. Then plug the cable (with 
the adapter) into the video port on your 
Macintosh.
4. Tighten the screws on the connectors.
Connecting the Mouse Cable
To use the remote control as a mouse, follow the steps below. 
If the Macintosh has a USB port, you can use the USB mouse cable 
that came with the projector. If it has a round mouse port, you’ll need 
a Macintosh ADB mouse cable. See your projector dealer for help in 
obtaining the correct cable.
1. Connect one end of the mouse cable to the projector’s USB port. 
 
2. Disconnect your Macintosh’s mouse cable. Connect the other end 
of the projector’s mouse cable to a USB port on your Macintosh.

Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speakers, you can use a computer audio cable. The 
required cable (3.5-mm stereo miniplug cable) is available from 
computer or electronics dealers.
1. Connect one end of the audio cable to the 
Audio In port on the 
projector. 
  
2. Connect the other end of the audio cable to the speaker or 
audio-out jack on the Macintosh.       
Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions 
up to 1600
×1200 pixels. Since 1280×1024 pixels is the default 
resolution for most leading workstations, your projector is ideal for 
displaying workstation video output.
There is no standard for workstation video output. Workstations that 
follow the SXGA standard and use the HD15 (standard VGA) 
connector won’t need an adapter cable or any special connection 
device. However, your system may vary; contact your computer dealer 
if you need help connecting your workstation.

Appendix B: Notices81
Appendix B: Notices
This appendix includes safety instructions and other important 
information about your EPSON PowerLite 703c.
Important Safety Instructions
Follow these safety instructions when setting up and using the 
projector:

Do not place the projector on an unstable cart, stand, or table.

Do not use the projector near water or sources of heat.

Use attachments only as recommended.

Use the type of power source indicated on the projector. If you are 
not sure of the power available, consult your dealer or power 
company.

Place the projector near a wall outlet where the plug can be easily 
unplugged. 
Placez le projecteur près d’une prise de contacte où la fiche peut être 
débranchée facilement.

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. Do not hold the plug with wet hands.

Take the following precautions for the plug. Failure to comply 
with these precautions could result in sparks or fire: Do not insert 
the plug into an outlet with dust present. Insert the plug firmly 
into the outlet.

Do not overload wall outlets, extension cords, or integral 
convenience receptacles. This can cause fire or electric shock. 
						

							82Appendix B: Notices

Do not place the projector where the cord can be walked on. This 
may result in fraying or damage to the plug.

Unplug the projector from the wall outlet before cleaning. Use a 
damp cloth for cleaning. Do not use liquid or aerosol cleaners.

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

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

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

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

Do not place the projector and remote control on top of 
heat-producing equipment or in a hot location.

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. If liquid has been 
spilled into the projector, or if it has been exposed to rain or 
water. If it does not operate normally when you follow the 
operating instructions, or if it exhibits a distinct change in 
performance, indicating a need for service. If it has been dropped 
or the housing has been damaged.

If you use the projector in a country other than where you 
purchased it, use the correct power cord for that country.

Do not stand on the projector or place heavy objects on it.

Do not attempt to remove the lamp immediately after use. Allow 
the lamp to cool for approximately one hour before removing it.

Do not use the projector outside of the required temperature 
range (41 to 95 °F). Doing so may cause an unstable display and 
an excessive load on the fan, leading to projector damage.  
						

							Appendix B: Notices83

Do not store the projector outside of the required temperature 
range (14 to 140 °F) or in direct sunlight for long periods of time. 
Doing so may cause damage to the case.

Do not use the projector with the lens cap in place. The heat 
generated by the lens may damage the cap.

The liquid crystal display panel contains more than 99.99% active 
pixels. However, 0.01% of the pixels may be missing or constantly 
illuminated.
Remote Control Information
You can operate the projector by remote control via a line-of-sight 
infrared (IR) receiver at the front and rear 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:

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 correctly, you can always run 
your computer-based presentation directly from the computer.
