DCT3080 Installation Manual Installation This section provides instructions to cable the DCT3080 and check its operation. The cabling diagrams illustrate connections to high-definition or standard-definition TVs, home theater receivers, and stereo VCRs. Important Safety Considerations The DCT3080 requires careful handling to avoid potential damage to its internal hard disk drive or the loss of recorded data. Be sure to follow these requirements during transportation and installation.
DCT3080 Installation Manual • • • • • consumer electronics devices, such as stereo receiver/amplifiers and televisions, is permitted as long as the air surrounding the terminal does not exceed 40 ºC (104 ºF). Place the terminal on a flat surface not prone to vibration or impact. Do not install the terminal in an area where condensation occurs. To prevent the temporary loss of guide data and cause a temporarily non-responding terminal, do not plug the AC power cord into a switched power outlet.
DCT3080 Installation Manual 1 Start the Diagnostics as described in Section 4, “Diagnostics.” d 01 is displayed on the front-panel LED. 2 Using a remote control, within five seconds press REPLAY, MY DVR three times, and LIVE TV. (On some remote controls, the MY DVR key may be labeled “LIST.”) If you correctly enter this key sequence in five seconds or less, the hard drive is cleared and the front-panel LED displays Clr. 3 If Clr is not displayed, re-enter the key sequence in step 2.
DCT3080 Installation Manual Audio Connection Options Connect the stereo audio cable to the AUDIO R and L connectors on the DCT3080 and the audio left and right connectors on the TV. If the equipment supports it, use the OPTICAL SPDIF or coaxial digital SPDIF output instead of the AUDIO R and L outputs. In most cases, these outputs offer better audio quality, including support for 5.1 Surround Sound.
DCT3080 Installation Manual Installation Overview You are connecting to a standard definition TV – Connect the S-VIDEO connector using an S-video cable, or connect the composite VIDEO connector using an RCA phono cable. If the TV only has a coaxial RF input, connect it to the DCT3080 RF OUT connector. Determine if you are connecting the audio to a home theater receiver or directly to the TV: If the receiver or TV has an SPDIF input, use the optical spdif or coaxial spdif outputs.
DCT3080 Installation Manual Connecting to an A/V Receiver – Audio Only Connect the stereo audio cable to the AUDIO R and L connectors on the cable terminal and the corresponding connectors on the HDTV. If your equipment supports it, use the OPTICAL SPDIF or coaxial digital SPDIF outputs instead of the AUDIO R and L outputs. In most cases, SPDIF offers better audio quality, including support for Dolby 5.1 Surround Sound.
DCT3080 Installation Manual Connecting to a Stereo TV Depending on the TV’s inputs: If possible, use the S-VIDEO and AUDIO connectors on the DCT3080. If the TV has no S-Video input, use the composite VIDEO and AUDIO connectors on the DCT3080. If the TV has an RF input only, use the RF OUT connector on the cable terminal.
