Change the Way You Watch TV  
DVR makes it easy to watch TV on your terms.  
The Explorer 8240HD Digital Video Recorder (DVR) is the simple way to take control over your  
TV – and your life. You take control because DVR lets you decide what’s on TV and when. So  
there’s no more putting off the things you need to do, just because there’s a show on TV you want  
to watch. Just think what DVR can do for you:  
Never miss a minute of your favorite movie or the big game. Simply pause the live action and  
play again when you’re ready. You can even rewind what you missed.  
Two of your favorite shows on at the same time? Simple. Just record one program while you  
watch the other. You can even record two programs at the same time while watching a  
previously recorded program. Your VCR can’t do that.  
Is your favorite sports team having an away game and you can’t go? Imagine being able to  
record it and watch it in High Definition (HD) at a more convenient time. In HD, the picture is so  
clear you’ll almost forget that you’re not there.  
Don’t miss another minute of the TV shows you love!  
Follow the instructions in this guide to install the 8240HD, to become familiar with the buttons on  
the front panel, and to access your cable services. Then, enjoy the features of the 8240HD and  
change the way you watch TV!

Frequently Asked Questions About HDTV  
What is Digital Television?  
Digital television (DTV) is a huge leap forward in television technology compared to analog  
television that has been widely available since the 1940s. DTV is delivered and displayed using  
digital encoding, similar to the way a PC operates. By using digital technology, there is no variation  
in picture and sound quality from the origination point until it is displayed on your television. You  
always receive a high-quality picture without the wavy lines or static you might sometimes get from  
a weak analog signal.  
Because DTV receives and displays digital images that contain many times more picture elements  
(pixels - the small dots that make up the color image on your screen) than standard analog  
television, you can get a sharper on-screen image than with analog. Additionally, DTV supports  
CD-quality sound. DTV includes SDTV (Standard Definition Television), EDTV (Enhanced  
Definition Television), and HDTV (High-Definition Television). That means that all HDTV is digital,  
but not all digital TV is high-definition. A high-definition program must originate in HD format and be  
broadcast in HD format. Having an HDTV system does not mean that everything you watch will be  
in high-definition. Getting the signal from digital cable also does not mean it is high-definition.  
What is Standard-Definition Television?  
Standard-definition television (SDTV) is basic digital television programming delivered by cable.  
Typically, the SDTV screen is the same, nearly square shape as an analog television screen.  
Digital images on an SDTV set are crisp and clear—noticeably better than on a standard analog  
television set using an antenna to receive over-the-air signals.  
What is High-Definition Television?  
High-definition television (HDTV) is a completely new way to send and receive television broadcast  
signals. HDTV images are made up of pixels that are much smaller and closer together than those  
used in standard analog television, and there are millions of them. Thus, HDTV can display five to  
six times the detail of analog television to deliver picture quality that is much more realistic,  
dimensional, and precise. SDTV programs can be viewed on an HDTV. Another feature of HDTV is  
digital surround sound using Dolby Digital®, which is the same technology used to produce the  
sound you hear in movie theaters.  
Are Local TV Stations Broadcasting in HDTV?  
Many local TV stations are transmitting digital signals. However, transmitting a digital signal does not  
mean transmitting an HDTV signal. Some stations are using the new bandwidth to broadcast several  
standard-definition channels. Most stations, once they begin broadcasting in digital, are offering HD  
content from their parent network (for example, CBS, ABC, NBC, Fox, WB, UPN, and PBS).  
Why Are Some HDTVs 4:3 Aspect Ratio and Others 16:9?  
The aspect ratios differ because television manufacturers build both standard-screen and wide-  
screen HDTVs to appeal to consumer viewing preferences. The two aspect ratios are as follows:  
On wide-screen (16:9) HDTVs, the programming is displayed on the full screen.  
On standard-screen (4:3) HDTVs, the programming is displayed in letterbox format in the middle  
of the screen. (There are bars surrounding the picture.)  
Where Are the Connection Diagrams?  
The diagrams at the end of this guide show examples of common ways to connect the 8240HD to  
your HDTV, DVD, and home theater receiver. However, these diagrams do not show every  
possible combination of devices. Refer to the user’s guides that came with your other electronic  
devices for further information.  
What Cables Do I Need?  
Some of the cables and adaptors shown in the diagrams may not be included with the 8240HD.  
The required cables are shown in the connection diagrams in this guide.

Picture Formats  
What is the Difference Between a Standard-Screen and a  
Wide-Screen HDTV  
The type of screen your HDTV has (wide screen or standard screen) determines how the 8240HD  
displays programs on the screen. The picture format for an HDTV is a combination of aspect ratio  
and screen resolution and is different for standard-screen and wide-screen HDTVs.  
What is Aspect Ratio?  
An aspect ratio is the ratio of the width to the height of the TV screen. The aspect ratios differ  
because the television industry manufactures both standard-screen and wide-screen HDTVs to  
appeal to consumer viewing preferences.  
What is the Screen Resolution and Scan Rate?  
The screen resolution indicates the amount of detail that the picture displays. Resolution is  
identified by the number of display lines on the screen. The techniques that an HDTV uses to  
“paint” the picture on the screen are referred to as progressive and interlaced.  
With the progressive method, every pixel on the screen is refreshed simultaneously. The  
interlace method involves refreshing pixels in alternation — first the odd lines and then the even  
lines.  
For advance setup, select the scan modes that your TV can support. Refer to your DVR and HDTV  
user’s guides to choose the proper scan rates (480i, 480p, 720p, 1080i) for your setup.  
For example, a resolution of 1080i indicates that the screen shows 1080 lines in an interlaced  
display, and 480p indicates that the screens shows 480 lines in a progressive display.  
Notes:  
The screen resolution (1080i, 480p, and so forth) is sometimes referred to as the scan rate.  
The terms are interchangeable.  
You can stretch and zoom the displayed picture using the built-in capability of the 8240HD by  
pressing the # key on the remote control. Refer to your DVR user’s guide for more information  
on this feature.  
A standard-screen HDTV has a 4x3  
aspect ratio. The screen is 4 units wide for  
every 3 units tall.  
A wide-screen HDTV is one-third wider than a  
standard-screen HDTV. The screen is 16 units  
wide for every 9 units tall.

Connecting the 8240HD to an HDTV With an  
HDMI Connector  
WARNING:  
Electric shock hazard! Unplug all electronic devices before connecting or disconnecting any  
device cables to the 8240HD.  
Important Note Regarding the HDMI Interface on the 8240HD  
The HDMI interface will automatically configure the audio output for a format supported by the  
television. Because not all TVs support a DolbyDigital input, the HDMI interface may automatically  
select a 2-channel stereo audio configuration instead of Dolby Digital. When the output is  
configured for 2-channel audio, this configuration is carried over to the other digital audio outputs  
of the 8240HD. This configuration prevents your home theater system or Dolby Digital decoder  
from providing the full Dolby Digital surround sound effect.  
On the 8240HD, you may override the automatic selection of audio by the HDMI interface by  
completing the following steps.  
1. Press SETTINGS twice on the remote control to open the General Settings menu.  
2. Press MOVE UP or MOVE DOWN to select the option Audio: Digital Out.  
3. Press MOVE RIGHT to select Dolby Digital. This setting will send Dolby Digital audio to the  
HDMI, DIGITAL AUDIO OUT, and OPTICAL AUDIO OUT connectors on the 8240HD.  
Note: If the TV (video/audio monitor) connected to the 8240HD using HDMI is not Dolby Digital  
capable, it may not produce audio through its speakers when the Audio: Digital Out setting on the  
8240HD is set to Dolby Digital. You can either switch the Audio: Digital Out setting back to HDMI  
when you are not using the home theater or Dolby Digital decoder, or you can connect the  
baseband audio outputs (OUT 1 Audio Left and Right) to the TV.

Guidelines for Using the External SATA Hard Disk Drive  
The external SATA hard disk drive requires continuous power. If the SATA drive loses power while  
the 8240HD is plugged in, the 8240HD may stop current recordings or not provide enough space  
for future recordings. Follow these guidelines for using the SATA drive:  
Do not plug in the power cord for the SATA drive to a switched outlet or to the AC outlet on the  
8240HD.  
Do not turn off, disconnect, or unplug the SATA drive while the 8240HD is plugged in.  
Recommendations for the SATA Drive  
Contact your cable service provider for a list of approved external SATA hard disk drives. At a  
minimum, your SATA drive should have these capabilities:  
information)  
Drive Speed: 7200 RPM (5400 RPM without Multi-room); 133 MB/sec

drive as follows:  
• A recording is not split between an internal and external hard drive.  
• The 8240HD automatically stores complete programs using the following space available logic:  
- If the external SATA drive has more space available, the SATA drive stores the next recording.  
- If the internal hard drive on the 8240HD has more space available, the internal hard drive  
stores the next recording.
