3 INSTALLATION Before You Begin Before you move or change components on the subscriber’s entertainment system: • Review the installation instructions. • Determine if you are connecting to a standard analog NTSC TV (supporting an RF input), a composite (baseband) video input, or a High-Definition TV (supporting component video input, HDMI™ input, or an IEEE-1394 input). • Determine if the subscriber has other equipment to be connected to the terminal (home theater or A/V receiver, VCR, etc.).
3 INSTALLATION Video Connection Options Use the following guidelines to determine the best video connection for the subscriber’s home entertainment system. To determine the available video inputs on the TV, check the manual supplied with the TV or the TV itself. The DCX3200 offers the following video outputs: Component (YPbPr) HDTV and SDTV The YPbPr output provides three component analog video signals to the TV. It is the most widely supported HD video connection.
3 INSTALLATION Audio Connection Options When connecting to a home theater receiver, depending on its inputs, you can use the following DCX3200 audio outputs: HDMI Unlike a DVI connection, an HDMI™ connection is capable of carrying digital video and audio signals to the TV or a home theater receiver equipped with HDMI™ switching support. The HDMI™ connection can deliver Dolby® Digital Plus, Dolby® Digital, Linear PCM, and other digital audio formats to a compatible TV or home theater receiver.
3 INSTALLATION 2. Determine if you are connecting the audio to a home theater receiver or directly to the TV: • For an HDMI™ or IEEE-1394 video connection, no additional audio connections to the TV are required. • If the receiver or TV has a digital audio (S/PDIF) input, use the digital audio OPTICAL (S/PDIF) or COAXIAL (S/PDIF) outputs. • Otherwise, use the baseband left and right audio outputs. 3. Locate the cabling diagram(s) that best match the subscriber’s configuration. 4.

3 INSTALLATION Connecting HDTV — Separate Video/Audio Connections Cable In Connect an RF coaxial cable to the cable wall outlet and the Cable In connector on the DCX set-top. DVI If the TV has a DVI input, use the DVI connection for the video: • Connect a HDMI-to-DVI adapter or cable to the HDMI™ out connector on the DCX set-top and the DVI connector on the TV. Note: A DVI connection supports only the video connection between the DCX set-top and the HDTV.

3 INSTALLATION Connecting an A/V Receiver — Audio There are several options available for audio connections to the A/V receiver: • Digital audio (OPTICAL S/PDIF) • Digital audio (COAXIAL S/PDIF) • Stereo audio (AUDIO L and R) If the A/V receiver supports it, the optical (S/PDIF) or coaxial (S/PDIF) audio outputs may be used in place of the stereo audio outputs (AUDIO L and R). These outputs offer a higher level of audio quality, including support for Dolby® Digital audio.

5 TROUBLESHOOTING Troubleshooting guidelines follow. If problems still occur after performing the diagnostics, call the TRC for assistance as described in the Introduction. Problem Possible Solution The DCX settop will not power on The DCX set-top may have received a software update and may not power on while the new software is being installed. Try again in a few minutes. The remote control does not work • Verify that the AC power cord is connected to the DCX set-top and an AC outlet.
5 TROUBLESHOOTING Problem Possible Solution There is no video on the TV screen Verify that the TV is powered on and set to the appropriate input source for the DCX set-top. Verify that the DCX set-top is powered on and tuned to an authorized cable channel. Verify that all video cables between the DCX set-top and the TV are firmly connected. Verify that the coaxial cable feed is firmly connected to the DCX set-top and the wall jack.
5 TROUBLESHOOTING Problem Possible Solution There are black bars above and below the picture All 4:3 HDTVs display HD programs in letterbox format (black bars above and below the picture) because of the shape of the display screen. • Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables most standard-screen TVs to display a full screen picture when the DCX3200 is tuned to a 4:3 program. • Set the TV TYPE to 4:3 Pan-Scan.
