Important Safety Considerations
An advanced set-top containing an internal hard drive requires careful handling to avoid
damaging the drive. Be sure to follow these guidelines.
During Transportation to the Subscriber Home
Transport the set-top in its shipping box or an equally padded container.
Transport the set-top in a vehicle from 41ºF (5ºC) to 122ºF (50ºC).
Do not expose the set-top to rain or moisture.
Do not drop the set-top or expose the set-top to shock or vibration.
To avoid damage from condensation, avoid drastic temperature changes.
During Installation
To maintain normal operating temperature, provide for adequate ventilation and airflow
around the set-top. If you must transport or store the set-top in a cold or hot vehicle, allow time
for the set-top to adapt to the temperature in the subscriber home before applying AC power.

Position the set-top on a flat surface with at least 2 inches of air space above and on all sides to
allow free airflow around the unit.
Do not block the slots, openings, and air vents on the set-top.
Do not place anything on top of the set-top.
Do not position the set-top in an enclosed entertainment center or cabinet that does not provide
adequate ventilation.
DCT6400 Series Installation Manual
3-2
Installation
Do not position the set-top near any external heat source that could raise the temperature
around the unit. Do not place the set-top on top of another heat-producing electronic device.
Do not plug the AC power cord into a switched power outlet.
Before applying AC power, ground the set-top by connecting it to the coaxial cable wall outlet.
Do not apply power until the set-top has acclimated to the operating environment. It should
acclimate 54ºF (30ºC) per hour to a temperate change. For example, consider moving a set-top
that has been in a 41ºF (5ºC) truck for more than one hour into a subscriber home with a
temperature of 77ºF (25ºC). In this case, you should allow the set-top to warm up for at least 40
minutes before applying power.
Do not apply power to set-top until it reaches a safe operating temperature of 59 to 104ºF
(15 to 40ºC) and 5 to 90% non-condensing humidity.
To allow the internal disk drive to spin down and park its heads, wait 10 seconds after
disconnecting power before moving the set-top.
Before You Begin
Before you move or change components on the subscriber entertainment system:
Review the installation instructions.
Determine if you are connecting the set-top to a standard TV, a composite (baseband)
monitor, or a component monitor.
Verify that you have the necessary audio/visual cables and other required items.
If the set-top was previously used, clear its hard drive before installing the set-top at a new
subscriber location
Clearing the Hard Drive
On a previously-used set-top, delete all recorded programs from the hard drive before installing it
at a new subscriber location. This prevents your new subscriber from viewing programming they
may not have purchased or may not want to see.
To prevent subscribers from accidentally deleting all of their recorded programs, a specific set of
keystrokes is required to clear the hard drive. Having a TV connected to the set-top is optional.
To clear the hard drive:
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
If Clr is displayed, press any other key to reset the set-top, turn it off, and complete the
clearing process.

Video Connection Options
Use the following guidelines to determine the best video connection for the subscriber home
entertainment system.
To determine the available video inputs on the TV, check the manual supplied with the TV.
The DCT6400 offers the following video outputs:
Component
video (Y Pb Pr)
HDTV and
SDTV
The Y Pb Pr outputs provide component video, the most widely supported HD
video connection.
S-Video
SDTV only
If the TV has no component video inputs, use the S-Video connection.
Video
(composite)
SDTV only
If the TV has no S-Video inputs, use the composite video (VIDEO) connection.
RF
SDTV only
If the TV only has an RF input, connect the DCT6400 using an RF Modulator,
which can be purchased at most electronics stores.
DVI-D
or
IEEE 1394
HDTV and
SDTV
DVI and IEEE 1394 offer higher quality HD video than component video.
If the TV has a DVI input, use the DVI-D output on the set-top instead of the
IEEE 1394 connection.
The IEEE 1394 is a video and audio connection, so no audio connections are
required if you use the IEEE 1394 connection and plan to use the TV’s
speakers as the primary audio source.
Audio Connection Options
Connect the stereo audio cable to the AUDIO R and L connectors on the DCT6400 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.
When connecting to a home theater receiver, depending on the capabilities of the receiver, you
can use the following audio outputs on the set-top:
coaxial SPDIF
If the receiver supports it, use the OPTICAL SPDIF or coaxial SPDIF audio output to deliver
Dolby AC-3 audio to a Dolby Digital home theater receiver.
Baseband
and L
If the audio receiver does not support Dolby Digital, use the baseband AUDIO R and L
outputs to connect to the audio receiver.
OPTICAL SPDIF or
AUDIO R
The cabling diagrams show sample audio/video connections to an audio receiver, where the
receiver functions as an audio/video router. When connecting to an audio receiver, reference its
installation instructions for directions on connecting to baseband and S/PDIF ports.
The VCR and TV receive their audio/video signals from the currently selected input device on the
audio receiver. This is important when the subscriber has another audio/video device such as a
DVD player, a secondary VCR, a CD player, or other electronic component. We recommend
connecting the TV to the monitor output so on-screen menus for the receiver can be displayed. (In
many cases the receivers themselves have interactive on-screen menus).

Determine if you are connecting the set-top to a:
High-definition TV
or monitor
Use the component video (Y Pb Pr), DVI-D, or IEEE 1394 outputs. No other video
connection supports HDTV.
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 an RF input, use an
RF Modulator, which can be purchased at most electronics stores.
Determine if you are connecting the audio to a home theater receiver or directly to the TV:
For an IEEE 1394 connection, no audio connections are required to the TV.
If the receiver or TV has a S/PDIF input, use the OPTICAL SPDIF or coaxial SPDIF outputs.
Otherwise, use the baseband left and right AUDIO OUT outputs.

Cabling to an HDTV for Video
For HDTV video, for the best possible video quality:
If the TV has a DVI input, connect to the DVI-D connector on the set-top.
If the TV has no DVI input but does have an IEEE 1394 connector, connect to the
IEEE 1394 connector on the set-top. Because IEEE 1394 is a video and audio connection, no
audio connections to the TV are required if you use this method.
Otherwise, use the component video (Y, Pb, and Pr) connectors.

Installing the Optional IR Blaster
The optional IR Blaster provides control of the subscriber VCR from the set-top. It consists of a
low-power infrared transmitter attached to a six-foot cord and a mounting bracket. The
mounting bracket is a clear plastic holder that has a pad of adhesive tape that enables you to
install the IR Blaster near the VCR IR receiver. A mini-pin connector at the end of the cord
connects the IR Blaster to the set-top. The IR Blaster is sold separately as an accessory item.
The availability and functionality of the IR Blaster depends on the installed application
software. Some EPGs may not support the IR Blaster.
Figure 3-5
IR transmitter installed in mounting bracket
Once installed, the IR Blaster is activated automatically through the electronic program guide.
Individual VCR codes are broadcast through the out-of-band data channel and are updated
periodically as new codes are added.
The procedure for installing the IR Blaster is described in the following paragraphs.
Locating the IR Receiver on the VCR
The IR receiver area is not visible on some VCRs. To locate it:
Obtain a piece of opaque material, such as a 3- by 5-inch index card.
Use the card to block off areas of the VCR where the IR receiver might be located. Try to
turn the VCR on and off with the remote control pointed directly at it, and close enough to
reduce the possibility that the receiver will see IR reflections.
Note the blocked area where the VCR is unresponsive to the remote control. This region
contains the sensor and can be marked by loosely taping the index card to the area.
Because the IR Blaster radiates in an area approximately 40 degrees wide, you do not need to
be precisely on target with the receiver. You may prefer to offset the location of the IR Blaster
transmitter so that it is less likely to interfere with operation of the VCR remote control.

Boot Cycle
After connecting the proper cabling to the set-top, plug the power cord into the set-top and
electrical wall outlet. Begin performing the boot cycle procedure:
After a few moments, the LED displays HUNT and then FR 1.
The set-top searches for the headend out-of-band (OOB) frequency carrier. If the OOB
frequency is not set to 75.25 MHz, the LED flashes FR 1 and then flashes FR 2. This
searching process repeats until the correct OOB frequency is found and the required
message for the set-top model is acquired.
The LED displays and OOB frequencies are:

When the correct OOB frequency is acquired, the LED flashes FR number.
When multiple OOB frequencies are used, the set-top pauses 40 seconds on each valid
frequency. The LED displays dl and a progress indicator, which identifies a software object
download. The progress indicator, or crawling ant, moves one position around the dl display
for each segment of download received. If the dl stops moving up and down on the LED for
an extended period of time, contact the headend operator.
The progress indicator usually moves at a consistent rate as segment downloads are
received. If all the segments are retrieved in the first pass, the EF, AU and FP messages are
displayed on the LED. If segments are dropped, the progress indicator appears to stall and
then inch forward after the dropped segments are retired.

The software download may take up to 45 minutes (or longer if the system is experiencing
high demand). As long as the progress indicator is spinning, the download is progressing.
When the progress indicator alternates between rapid and sluggish movement, this may
indicate that the stream is spinning too fast for existing plant conditions.
When the software object download is complete, the LED displays:
EF
For up to 60 seconds during flash erasure
FP
For up to 60 seconds during flash programming
When the LED display is blank, the set-top is ready for initialization and service
authorization using the addressable controller. Verify that the set-top is powered up or reset

Troubleshooting
This section provides troubleshooting guidelines. If problems still occur after performing the
diagnostics, call the TRC for assistance as described in Section 1, “Introduction.”
Problem
Possible Solutions
The set-top will not
power on.
The 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.
Verify that the AC power cord is connected to the set-top and an AC outlet.
Unplug the set-top from the AC outlet, plug it back in, and then press the
POWER button.
If the set-top is connected to a switched outlet on another unit, verify that that unit
is powered on. Unplug the power cord from the set-top’s AC outlet, plug it back it
in, and then press the POWER button.
Press the POWER button on the set-top front panel instead of the remote control.
The batteries in the remote control may be depleted.
The remote control does
not work.
Verify that the remote control is in “Cable” mode.
Verify that there are no obstructions between the remote control and the set-top.
Aim the remote control directly at the set-top front panel, not the TV or VCR.
The angle between the remote control and the set-top may be too large. Stand in
front of the set-top and not too far to either side.
Press and release operation keys one at a time, firmly and deliberately.
Try changing channels using the buttons on the set-top front panel.
Check the batteries in the remote control. Install new batteries if needed.
There is no audio when
viewing cable channels.
Verify that the MUTE button on the set-top or the remote control has not been
pressed. Press MUTE on the remote control to restore sound.
If the set-top audio output is connected to the TV, verify that the Mute button on
the TV has not been pressed.
If the set-top audio output is connected to a home theater receiver, verify that the
receiver is set to the appropriate input source and the MUTE button on the receiver
has not been pressed.
Verify that you have the correct cables for the audio ports.
Verify that the audio cables are firmly connected between the set-top and the TV,
VCR, or home theater receiver.
There is no audio from
the center and/or
surround speakers of a
home theater receiver
connected to the set-top.
Not all Dolby Digital programs feature full 5.1 surround sound. In some cases, the
programs may only contain left and right stereo audio.
Verify that the S/PDIF cable (coaxial or optical) is firmly connected to the set-top
and the home theater receiver.
Verify that the home theater receiver is set to a surround sound audio mode
(Dolby Digital, Dolby Pro Logic®, or Dolby Pro Logic II.
Verify that the receiver is properly configured to work with all connected
speakers.

Troubleshooting
Problem
Possible Solutions
There is no video on the
TV screen.
Verify that the TV is powered on and set to the appropriate input source for the
set-top.
Verify that the set-top is powered on and tuned to an authorized cable channel.
Verify that the coaxial cable is firmly connected to the set-top and the wall jack.
Verify that all video cables between the set-top and the TV are firmly connected.
The set-top DVI output may not yet be enabled. Use the component video
(Y Pb Pr) output instead.
If the set-top video output is connected to a home theater unit, verify that the
home theater unit is powered on and set to the appropriate input source.
Not all HDTVs can display every output format (1080i, 720p, 480p, or 480i)
available on the DCT6400 Series. To select a different format:
There are no graphics,
closed captions, or
program guides
appearing on the TV
screen.
1
Ensure that your set-top is plugged into a power outlet and is turned off.
2
Press the MENU key on the front panel. Your settings are displayed on the
front panel.
3
Press the ▲ and ▼ keys to display the DVI/YPbPr OUTPUT setting.
4
Press the ► key to cycle through the available output formats until a picture
displays on the TV.
The set-top cannot generate graphics on all video outputs at all times. If the
set-top is set to 1080i, 720p, or 480p output format, graphics are only available
on the high definition video outputs (DVI and component video). If the set-top is
set to 480i, graphics are available on all video outputs. For more information, see
“Graphics Overlaying the Video” in Section 3, “Installation.”
If the set-top is connected to a standard definition (SD) TV, verify that the set-top
is configured to use the 480i output mode.
Verify that closed captions on the set-top have been enabled in the User Settings
menu.
There are black bars to
the right and left of the
picture.
Wide screen TVs display 4:3 programs in this format unless set to Stretch. Turn
on the 4:3 OVERRIDE feature in the User Settings menu. This enables most
wide screen TVs to stretch the video to fill the screen (see the TV manual for
information about stretching 4:3 video).
If the set-top is connected to a wide screen TV, verify that the TV TYPE is set to
16:9 in the User Settings menu.
Many HD programs are broadcast in pillar-box format with black bars to the left
and right of the picture. These programs are broadcast in 16:9 HD formats even
though the video is not 16:9.
DCT6400 Series Installation Manual
Troubleshooting
Problem
Possible Solutions
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.
5-3
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 set-top is
tuned to a 4:3 program.
Set the TV TYPE to 4:3 Pan-Scan. This enables the set-top to remove the black
bars above and below the picture when possible.
Some SD programs are broadcast in the letterbox format with black bars above
and below the picture. Some wide screens TVs offer a zoom feature that may be
able to remove the black bars (see the TV manual for information about zooming
4:3 video).
There are black bars on
all four sides of the
picture.
This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To cause 4:3
SD programming to fill the screen, depending on the capabilities of the TV, set
4:3 OVERRIDE to 480i or 480p.
This may occur on a 16:9 TV if the active video for an SD broadcast is in
letterbox format. To confirm, wait for a commercial or look for a graphic, such as
a network logo. If the commercial fills the screen from top to bottom, or the
graphic appears below the active video, the program is being letterboxed by the
broadcaster. You can minimize this by activating the zoom feature on the TV.
A broadcaster may include black bars on either side of a wide screen broadcast.
This is called a “hybrid” aspect ratio and results in a black border surrounding the
video on a 4:3 TV. Because this is part of the broadcast, the set-top cannot
correct the video. You may be able to minimize the border using the zoom feature
on the TV.
There is a humming
noise.
The DCT6400 series provides an internal fan to cool the integrated hard drive.
During normal operation, the fan emits a low humming noise, similar to a
personal computer. The volume varies occasionally when the fan speed adjusts
to changes in the temperature around the set-top. The hard drive remains on
even when the set-top is turned off.
