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 Component Video to VGA (D-Sub) adaptor cable 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. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with 
a D-Sub type connector) to the D-SUB IN socket on the projector.
3. If you wish to make use of the projector (mixed mono) speaker(s) in your 
presentations, take a suitable audio cable and connect one end of the cable to the audio 
output socket of the device, and the other end to the AUDIO socket of the projector. 
Once connected, the audio can be controlled by the projector On-Screen Display 
(OSD) menus. See Adjusting the sound on page 39 for details.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 19 for details.
• 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.
3. If you wish to make use of the projector (mixed mono) speaker(s) in your 
presentations, take a suitable audio cable and connect one end of the cable to the audio 
output socket of the device, and the other end to the AUDIO socket of the projector. 
Once connected, the audio can be controlled by the projector On-Screen Display 
(OSD) menus. See Adjusting the sound on page 39 for details.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 19 for details.
• 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 19 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.
3. If you wish to make use of the projector (mixed mono) speaker(s) in your 
presentations, take a suitable audio cable and connect one end of the cable to the audio 
output socket of the device, and the other end to the AUDIO socket of the projector. 
Once connected, the audio can be controlled by the projector On-Screen Display 
(OSD) menus. See Adjusting the sound on page 39 for details.

• 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 19 for details.
