To connect a video source to the projector:
1. Turn off the projector and video source if they are on.
2. If your video source uses a small, round, one-prong composite
(RCA) video connector, you'll need the audio/video cable that
comes with the projector. If your video source uses a large, round,
four-prong S-Video connector or a BNC type connector, you will
need to purchase the appropriate cable or use the cable that came
with your video source.
3. For composite video, connect the yellow RCA plug on one end of
the audio/video cable to the projector's Video jack. Connect the
other yellow RCA plug to the video-out jack of your video source.
