Chapter Two
INSTALLATION
Connecting VHF and UHF Antennas
Antennas with 300-ohm Flat Twin Leads
If you are using an off-air antenna (such as a roof antenna or “rabbit ears”) that has 300-ohm
twin flat leads, follow the directions below.
1
Place the wires from the twin
leads under the screws on the
300-75 ohm adaptor (not
supplied). Use a screwdriver
to tighten the screws.
2
Plug the adaptor into the “ANT
1 IN” terminal on the rear
panel.
Antennas with 75-ohm Round Leads
Plug the antenna lead into the
“ANT 1 IN” terminal on the
rear panel.
Separate VHF and UHF Antennas
If you have two separate antennas for your TV (one VHF and one UHF), you must combine
the two antenna signals before connecting the antennas to the TV. This procedure requires an
optional combiner-adaptor (available at most electronics shops).
1
Connect both antenna leads to the combiner.
2
Plug the combiner into the “ANT 1 IN” terminal on the rear
panel.
INSTALLATION
Connecting Cable TV
You can connect different cable systems to your TV, including cable without a cable box, and
cable with a cable box that descrambles some or all channels.
Cable without a Cable Box
If you want to connect cable, and you do not need to use a cable box:
Plug the incoming cable into
the “ANT 1 IN” terminal on the
rear panel.
Cable with a Cable box that Descrambles All Channels
œ This terminal might be labeled
1
Find the cable that is
connected to the ANTENNA
OUT terminal on your cable
box.
“ANT OUT”, “VHF OUT”,or
simply “OUT”.
2
Connect the other end of this
cable to the “ANT 1 IN”
terminal on the rear panel.
INSTALLATION
Connecting to a Cable Box that Descrambles Some Channels
If your cable box descrambles only some channels (such as premium channels), follow the
instructions below. You will need a two-way splitter, an RF (A/B) switch, and four lengths of
coaxial cable. (These items are available at most electronics stores.)
œ This terminal might be labeled
1
Find and disconnect the cable
that is connected to the
ANTENNA IN terminal on your
cable box.
“ANT IN”, “VHF IN”,or
simply “IN”.
2
Connect this cable to a twoway splitter. Connect a coaxial
cable between an OUTPUT
terminal on the splitter and the
IN terminal on the cable box.

3
Connect a coaxial cable
between the ANTENNA OUT
terminal on the cable box and
the B-IN terminal on the A/B
switch.
RF (A/B)
Switch
4
Connect another cable
between the other OUT
terminal on the splitter and the
A-IN terminal on the RF (A/B)
switch.
5
Connect the last coaxial cable
between the OUT terminal on
the RF (A/B) switch and the
“ANT 1 IN” terminal on the
rear panel.
After you’ve made this connection, set the A/B switch to the “A” position for normal viewing. Set the A/B
switch to the “B” position to view scrambled channels. (When you set the A/B switch to “B,” you will
need to tune your TV to the cable box’s output channel, which is usually channel 3 or 4.)
