Antenna input impedance of this unit is 75 Ohms. VHF/UHF 75 Ohm coaxial cable can be
connected to the antenna jack directly, if the antenna cable is 300 Ohm parallel flat feeder
cable, you need to use the 300 Ohm/75 Ohm converter to connect the antenna cable to the
antenna jack. For details, please refer to the following drawing:
Antennas with 300 Ohm Flat Twins Leads Antennas with 75 Ohm Round Leads

Follow the instructions in Viewing a VCR or Camcorder Tape to view your VCR tape.
Each VCR has a different back panel configuration.
When connecting a VCR, match the color of the connection terminal to the cable.
We recommend the use of cables with a Ferrite Core.
1. Unplug the cable or antenna from the back of the TV.
2. Connect the cable or antenna to the ANT In terminal on the back of the VCR.
3. Connect an RF cable between the ANT OUT terminal on the VCR and the ANT IN terminal
on the TV.
4. Connect a video cable between the VIDEO OUT jack on the VCR and the VIDEO IN jack
on the TV.
5. Connect audio cables between the AUDIO OUT jacks on the VCR and the AUDIO L/R
jacks on the TV.
• If you have a mono (non-stereo) VCR, use a Y-connector (not supplied) to hook up to the
right and left audio input jacks of the TV. If your VCR is stereo, you must connect two ca-
bles.

Component video separates the video into Y (Luminance (brightness)), Pb (Blue), and Pr
(Red) for enhanced video quality.
Be sure to match the component video and audio connections.
For example, if connecting the video cable to COMPONENT IN, connect the audio cable to
COMPONENT IN also.
Each DVD player/STB has a different back panel configuration.
When connecting a DVD player/STB, match the color of the connection terminal to the cable.
We recommend the use of cable with a Ferrite Core.
1. Connect a component cable between the COMPONENT IN (Y, PB, PR) jacks on the TV
and the COMPONENT (Y, PB, PR) jacks on the DVD player.
2. Connect the audio cables between the COMPONENT IN (AUDIO R/L) jacks on the TV and
the AUDIO OUT jacks on the DVD player.

What is HDMI?
HDMI, or high-definition multimedia interface, is a next-generation interface that enables the
transmission of digital audio and video signals using a single cable without compression.
Multimedia interface is a more accurate name for it, especially because it allows multiple
channels of digital audio (5.1 channels).
The difference between HGMI and DVI is that the HDMI device is smaller in size, has the
HDCP (High Bandwidth Digital Cop Protection) coding feature installed, and supports
multi-channel digital audio.
Each DVD player/STB has a different back panel configuration.
We recommend the use of cables with a Ferrite Core.
1. Connect an HDMI cable between the HDMI connector on the TV and the HDMI connector
on the DVD player/Set-Top Box.
