Setting Up the Projector 17
Connecting an S-Video Cable
If your video source has an S-Video jack, you can use it to project a
higher quality video image. However, you’ll need an S-Video cable,
which may be included with your video source, or may be purchased.
Before starting, make sure the projector and your DVD player or
other video source are turned off.
1. Insert one end of an S-Video cable into the projector’s S-Video
port.
2. Insert the other end into the S-Video output port of your video
source.
3. Connect the audio plugs on the RCA A/V cable as described on
page 16.
