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 web-
site “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 ter-
restrial antenna.

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.
