Connecting to an External Speaker or 
PA System
 
Although the projector’s internal speakers are enough for 
most small- or medium-size rooms, you can connect the 
projector to an external speaker or public address (PA) system 
for large rooms or to gain maximum benefit.
To connect the projector to an external sound system, you 
need to obtain an RCA-to-3.5 mm stereo audio cable. You 
can get one from your computer dealer.
1. Turn off the projector and speaker or PA system if they are 
on.
2. Connect the cable’s 3.5 mm stereo miniplug to the 
projector’s Audio Out jack. 
3. Connect the RCA plugs to the external amplified speaker 
or PA system. Insert the cable’s red plug into the Audio R 
jack, and the white plug into the Audio L jack.
♦Note: The internal speakers are disabled when an external 
audio system is used.

Turning the Equipment On and Off
Turn on the projector and its attached equipment in the 
following order.
1. Computer
2. Video source
3. Audio source (if different from computer or video source)
4. Projector
5. External speaker or PA system (if necessary)
When you turn off the equipment, do so in the reverse order.
Turning the Projector On and Off
1. Remove the projector lens cap.
2. When you plug in the projector power cord, the power 
indicator flashes orange for few seconds. Then the light 
remains orange.
3. Press the Power button on the remote control or 
operation panel. The power indicator 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.
♦Warning: Never look into the lens when the lamp is on. This can 
damage your eyes. It is especially important that children are not 
allowed to look into the lens.
♦Caution: When turning the projector on or off with the remote 
control, be sure to turn the remote control on first with the power 
switch.

After you press the power button to turn off the projector, a
confirmation message appears. If you want to turn off the 
projector, press the power button again. If you don’t want to 
turn off the projector, press any button. The fan will remain 
on and the operation indicator will flash orange for about one 
minute as the projector cools down.
When the projector has cooled down, the operation indicator 
stops flashing and remains orange.
♦Note: If you press the Power button to turn the projector back on 
while the operation indicator is orange, there may be a delay 
before a projected image appears.

Focusing and Positioning the Screen 
Image
When an image appears on the screen, check that it is in focus 
and correctly positioned on the screen.
•To focus the image, rotate the focus ring (the outer ring on 
the lens). 
•To adjust the size of the image, rotate the inner zoom ring. 
Rotate the zoom ring between W (wide) and T (tele) 
marks.

If you need to raise or lower the image on the screen, extend 
or retract the two feet at the bottom of the projector as 
follows:
1. Stand behind the projector and support the front of it 
while you lift the foot adjust levers above the feet. This 
unlocks the feet so they can move up and down freely. Do 
not let the projector drop.
♦Caution: Do not hold the projector by its lens. This can damage 
the lens.
2. While lifting the foot adjust levers, raise or lower the 
projector until the screen image is positioned correctly.
3. Release the lever to lock the feet in their new position.
4. To fine-tune the height of the projector, turn the feet 
clockwise to raise the height or anti-clockwise to lower it.

Resize Button 
The Resize button allows you to select the projection method 
for certain types of image input signals from a computer.
With images up to XGA size (1024 × 768) for the EMP-713/
703 or SVGA size (800 x 600) for the EMP-503, you can 
choose from two projection methods. You can either display 
the image in the center of the projection area(Window 
display) or display the image full size(Resize display).
You can also choose from two projection methods with 
images greater than XGA size for the EMP-713/703 or 
SVGA size for the EMP-503 : either project a portion of the 
image or project the entire image in a compressed format. 
The projector automatically reduces the image size to the 
projectors maximum resolution. The Resize button cannot 
be used with images at XGA size for the EMP-713/703 or 
SVGA size for the EMP-503 resolution.
When the image source is Video, the resize button lets you 
choose an aspect ratio either resize display or 16:9.
