Connecting Video source devices
You can connect your projector to various Video source devices that provide any one 
of the following output sockets:
• Component Video
• S-Video
• Video (composite)
You need only connect the projector to a Video source device using just one of the 
above connecting methods, however each provides a different level of video quality. 
The method you choose will most likely depend upon the availability of matching 
terminals on both the projector and the Video source device as described below:
Best video quality
The best available video connection method is Component Video (not to be confused 
with composite Video). Digital TV tuner and DVD players output Component Video 
natively, so if available on your devices, this should be your connection method of 
choice in preference to (composite) Video.
See Connecting a Component Video source device on page 15 for how to connect 
the projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite 
Video. If you have both composite Video and S-Video output terminals on your Video 
source device, you should elect to use the S-Video option.
See Connecting an S-Video source device on page 15 for how to connect the 
projector to an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less 
than optimal result from your projector, being the least video quality of the available 
methods described here.
See Connecting a composite Video source device on page 16 for how to connect the 
projector to a composite Video device.

Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component 
Video output sockets available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a Component Video source device:
1. Take a VGA (D-Sub) to HDTV (RCA) cable, Component Video cable or a 
Component Video to VGA (D-Sub) adaptor and connect the end with 3 RCA type 
connectors to the Component Video output sockets of the Video source device. 
Match the color of the plugs to the color of the sockets; green to green, blue to 
blue, and red to red.
2. If you are using the VGA (D-Sub) to HDTV (RCA) cable and the Component Video 
to VGA (D-Sub) adaptor, connect the other end of the cable (with a D-Sub type 
connector) to the Computer in 1 or Computer in 2 socket on the projector. If you 
are using the Component Video Cable, connect the other end of 3RCA type 
connectors to the Y Cb/Pb Cr/Pr sockets on the projector.
Important
•
If the selected video image is not displayed after the projector is turned on and the 
correct video source has been selected, check that the Video source device is turned on 
and operating correctly. Also check that the signal cables have been connected 
correctly.

Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video output 
socket available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an S-Video source device:
1. Take an S-Video cable and connect one end to the S-Video output socket of the 
Video source device.
2. Connect the other end of the S-Video cable to the S-Video socket on the projector.
Important
•
If the selected video image is not displayed after the projector is turned on and the 
correct video source has been selected, check that the Video source device is turned on 
and operating correctly. Also check that the signal cables have been connected 
correctly.
•If you have already made a Component Video connection between the projector and this 
S-Video source device using Component Video connections, you need not connect to 
this device using an S-Video connection as this makes an unnecessary second 
connection of poorer picture quality. See Connecting Video source devices on page 
14 for details.

Connecting a composite Video source device
Examine your Video source device to determine if it has a set of unused composite 
Video output sockets available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a composite Video source device:
1. Take a Video cable and connect one end to the composite Video output socket of 
the Video source device.
2. Connect the other end of the Video cable to the Video socket on the projector.
Important
•
If the selected video image is not displayed after the projector is turned on and the 
correct video source has been selected, check that the Video source device is turned on 
and operating correctly. Also check that the signal cables have been connected 
correctly.
•You need only connect to this device using a composite Video connection if Component 
Video and S-Video inputs are unavailable for use. See Connecting Video source 
devices on page 14 for details.
About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
• You can use a wireless microphone as long as a wireless module is attached to the
projectors microphone input jack and it works well with the associated devices. To
ensure a quality use of the wireless microphone, it is recommended that your
microphone conforms to the specifications listed in the table below.

Operation
Powering On/Off the Projector
Powering On the Projector:
1. Remove the projector lens cap.
2. Complete the AC power cord and peripheral signal cable(s) connections.
3. Press   to turn on the projector.
The projector takes a minute or so to warm up. 
4. Turn on your source (computer, notebook, DVD, etc.). The projector automatically
detects your source.
• If you are connecting multiple sources to the projector simultaneously, press 
SOURCE on the projector to select your desired signal or press your desired 
signal key on the remote control.
Warning
•
Remove the lens cap first before powering on.
•Never look into the lens when the lamp is on. This can damage your eyes.
•This focal point concentrates high temperature. Do not place any object near it to avoid 
possible fire hazard.
Powering Off the Projector:
1. Press   to turn off the projector lamp. You will see a message Power off appear
on the screen.   
2. Press   again to confirm.
• When the Power LED begins flashing, the projector has entered stand-by mode.
3. Disconnect the AC power cord from the electrical outlet and the projector.
4. Do not turn on the projector right after power off

Adjusting the Projector Height
The projector is equipped with an elevator foot to adjust the image height.
To raise or lower the image:
1. To raise or lower the image, press the elevator button and raise or lower the front
of the projector. Release the button to lock the adjustment.
2. To level the image on the screen, turn the tilt-adjustment feet to fine-tune the 
height.
Note
•
To avoid damaging the projector, make sure that the elevator foot and tilt-adjustment 
feet are fully retracted before placing the projector in its carrying case.
Adjusting the Projector Zoom and Focus
1. Focus the image by rotating the focus ring. A still image is recommended for focusing.

Adjusting Projection Image Size
Refer to the graphic and table below to determine the screen size and projection distance.
Note
•
Position the projector in a horizontal position; other positions can cause heat build-up 
and damage to the projector.
•Keep a space of 30 cm or more between the sides of the projector.
•Do not use the projector in a smoky environment. Smoke residue may build-up on 
critical parts and damage the projector or its performance
.
•Consult with your dealer for special installation such as suspending from a ceiling.
There is 3% tolerance among these numbers due to optical component variations. 
It is recommended that if you intend to permanently install the projector, you 
should physically test the projection size and distance using the actual projector in 
situ before you permanently install it, so as to make allowance for this projectors 
optical characteristics. This will help you determine the exact mounting position so 
that it best suits your installation location.
