16 INSTALLATION AND CONNECTIONS
Step 3: Depending on the video input capabili-
ties of your video display and the connections
available on your A/V receiver or surround
processor, make one of the following connec-
tions. For the highest video quality use compo-
nent video connections, if available. An S-Video
connection is the next best quality, followed by
a standard composite video connection.

Installation Notes
■ For this installation, make the connections
from the receiver or processor to your video
display and speakers as described in the
owner’s manuals for those products.
display and speakers as described in the
owner’s manuals for those products.
■ Only one type of audio connection is
required, either digital or analog. If possible,
a digital connection is preferred as that will
enable you to listen to DVD soundtracks
with the clarity, definition and channel
separation made possible by Dolby Digital
and DTS. However, if you do not yet have a
receiver capable of digital audio processing,
you will still benefit from an analog
connection so that the receiver may create
a multichannel soundfield using Dolby Pro
Logic or other matrix decoding.

DISASSEMBLY
CAUTION BEFORE STARTING SERVICING
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a
proper grounding treatment as required.
Many screws are used inside the unit. To prevent missing, dropping, etc. of the screws, always use a
magnetized screw driver in servicing. Several kinds of screws are used and some of them need special
cautions. That is, take care of the tapping screws securing molded patrs and fine pitch screws used to secure
metal parts. If they are used improperly, the screw holes will be easily damaged and the parts can not be fixed.
