Notes:
•Installing your projector on the
ceiling must be done by a
qualified technician. Contact
your dealer for more
information.
•Ensure that you have enough
ventilation around your
projector so heat can dissipate.
Do not cover the vents of the
projector.
•Do not use the projector in a
smoky environment.
•Do not use the projector where
temperatures vary greatly. The
projector must be used at
temperatures between 41 ℉
(5 ℃ ) and 104 ℉ (40 ℃ ).
②Connections
Connecting Attentions
• Turn off all equipments before making any connection.
• Use the proper cable for each connection.
• Insert the cable plugs firmly, loose connections may increase noise and reduce
performance of signals. When pulling out a cable, be sure to pull it out by the plug, not the
cable itself.
Connecting to a PC
You can connect the projector to a PC, a Notebook or a Macintosh with the supplied
VGA cable. The projector support VGA, SVGA, XGA, WXGA, SXGA and SXGA+ signal.
However, we recommend that you set the output mode of your computer to SVGA (DS-250)
or XGA (DX-280/300/380/400) to obtain the best performance.
Notes:
•When using with a notebook, be sure to connect the projector and notebook while the projector is in
standby mode and before turning on the power of the notebook. In most case, the output signal from the
notebook is not turned on unless connected to the projector before being powered up.
•Displaying an image on the notebook’s LCD screen does not necessarily mean it outputs the signal to the
projector. Usually, a combination function keys can enable/disable the external display. For details, refer to
the operation instructions supplied with your notebook.
•Do not tie your VGA cable and power cable together. Otherwise the picture signal will be interfered.

User’s Manual

Connecting to Equipment with Video Output
Connect your DVD’s composite video and audio outputs with the supplied AV cable.
Note:
•Usually, connect the video signal with the yellow line of the AV cable. And the white line for mono audio or
the left of stereo audio, the red line for right of stereo audio (Yellow = Video, White = Mono/L, Red = R).
Connecting to Equipment with S-video Output
Connect your DVD’s S-video output with the supplied S-video cable and audio outputs
with the supplied AV cable.
Note:
•The pins of the S-video connector are slim, plug the cable carefully.

User’s Manual
11
Connecting to Equipment with Component Video RCA Output
Connect your DVD’s component video outputs with the supplied AV cable. One more
AV cable is needed (commercially available) when you want to output audio from the
projector’s speaker.
When connecting the component cable, match the jack colors with the component
cable (Green = Y, Blue = Pb, Red = Pr).
Notes:
•The component output jacks of the DVD might be labeled as Y,Pb,Pr / Y,B-Y,R-Y / Y,Cb,Cr according to
the equipment.
•When non-interlaced source is connected to the video input (Video, S-video, Component Video) of the
projector, the projecting images might be abnormal (the screen would divide to two parts). Please change
the DVD output signal to interlaced signal.
Connecting to Equipment with Component Video RGB Output
Some equipment, such as some new DVDs and D-TV set-top box, can output their
component video signal with the RGB (or VGA) connector. Use the supplied VGA cable for
connection. Supported signal can be found in Appendix E on Page 29.
Note:
•The Audio In L and R jacks are shared between the VGA and all videos inputs.
