High Definition Television Receiver

The HDTV Receiver is capable of receiving signals from the cable, and/or
over-the-air antenna and sending the decoder signals to your TV.

Audio/Video Jacks and Cables

The Audio/Video jacks provide excellent picture and sound quality. They are
used for making most Audio/Video connections between components. The
Audio/Video jacks may be color coded (yellow for video, red for right audio,
and white for left audio). If your component has only one input for audio
(mono), connect it to the left (white L/mono) audio jack on the HDTV
Receiver.

Component Out Jacks and Cables

Component Cables are used to connect the HDTV Receiver to an industry
standard YPbPr compatible HD Monitor. Remember to connect the left and
right audio cables. A Component jack carries only the picture signals, not
the sound.

ANT LOOP OUT Jack, and RF Cable

ANT LOOP OUT provides an RF connection between the HDTV Receiver
and the TV and provides the signal of ANT IN jack to TV.

Attenuator

During initial installation and setup of your new Zenith HDTV Receiver, you
may need to install the 10 dB attenuator, to the Antenna input “ANT IN” ter­minal on the HDV420. Details are on page 9.

Remote Control

In addition to the HDTV Receiver, the remote control can be programmed to
control many other devices.

Batteries

To install the batteries, slide open the battery compartment and insert the
two AA batteries provided.

Make sure you have received all these items listed below with the High Definition Television Receiver.

Connections

Connecting to an Antenna

Before connecting an antenna

Dear consumer purchaser of Zenith High Definition Television Receiver HDV420.
In addition to the components and accessories supplied with your Zenith HDTV Receiver, we have included a small
device called a “10 dB Attenuator”. During initial installation and setup of your Zenith HDTV Receiver, you may need
to install the 10 dB attenuator to the Antenna input “ANT IN” on the HDV420. The HDV420 is a high performance,
high gain system intended for operation under normal and weak signal conditions, providing the best reception with
its optimum gain. However, there might be some reception areas where the signal strength is too high (e.g. due to
close proximity to a undesirable signal or transmitter), so we included an attenuator that lowers the incoming signal
strength (from the undesirable transmitter) to more normal levels. This 10 dB attenuator should be used only in a
reception area where an undesired signal strength is too high. One of the possible symptoms would be that after
your program/channel search, your HDTV receiver does not find all the local digital terrestrial channels available in
your area. (You can find HDTV channels/content information for your local broadcast area by going to Zenith web­site “WWW.ZENITH.COM” and clicking on “HDTV Program Schedule” under HDTV.) Please make sure that before
deciding to use the supplied attenuator device, you are using an appropriate and properly aligned UHF/VHF RF ter­restrial antenna.

11

Connect the “Antenna” to the “ANT IN” jack on the HDTV Receiver using a coaxial RF cable.

ote

There might be some areas where the signal strength could is too high. If so, you may need to connect the antenna
to an attenuator and screw the attenuator onto the “ANT IN” jack.

Display Formats Overview

The HDTV Tuner offers various display formats and multiple video outputs. When the HDTV Tuner is connected to
A/V systems, the HDTV Tuner can provide video signal formats 1080i, 720p, 480p, or 480i.
1080i, 720p and 480p modes are available for component video (YPbPr) and monitor outputs.
480i mode is available for VIDEO and S-VIDEO outputs.
The HDTV Tuner has two digital audio outputs; Dolby Digital 5.1 and PCM. The HDTV Tuner sends out digital audio
signal to OPTICAL and COAXIAL audio outputs when digital broadcastings are being received by the HDTV Tuner.

Connecting to an Analog monitor
