Antenna and Cable TV Connections
Combination VHF/UHF Antenna (Single 75 ohm cable or 300 ohm twin-lead wire)
Connect the 75 ohm cable from a combination VHF/UHF antenna to the antenna jack. If your combination antenna has a 300 ohm twin-
lead wire, use the 300-75 ohm matching transformer (not supplied).
Combination VHF/UHF Antenna (Separate VHF and UHF 300 ohm twin-lead)
Connect the UHF twin-lead wire to a combiner (not supplied). Connect the VHF twin-lead to the 300-75 ohm matching transformer (not
supplied). Attach the transformer to the combiner. Attach the combiner to the antenna jack.
Separate VHF/UHF Antenna
Connect the 75 ohm cable from the VHF antenna and the UHF antenna twin-lead to a combiner (not supplied). Attach the combiner to
the antenna jack.
Note: If your VHF antenna has a twin-lead wire, use the 300-75 ohm matching transformer (not supplied), then connect the transformer to the
combiner.
For Subscribers to Basic Cable TV Service
For basic cable service not requiring a converter/descrambler box, connect the CATV 75 ohm coaxial cable directly to the antenna jack on
the back of the television.
For Subscribers to Scrambled Cable TV Service
If you subscribe to a cable service which requires the use of a converter/descrambler box, connect the incoming cable to the converter/
descrambler box and connect the output of the box to the antenna jack on the back of the television. Follow the connections shown below.
Set the television to the output of the converter/descrambler box (usually channel 3 or 4) and use the converter/descrambler box to select
channels.
For Subscribers to Unscrambled Basic Cable with Scrambled Premium Channels
If you subscribe to a cable service in which basic cable channels are unscrambled and premium channels require the use of a converter/
descrambler box, you may wish to use a two-set signal splitter (sometimes called a "two-set coupler") and an A/B switch box from the cable
installer or an electronics supply store. Follow the connections shown below. With the switch in the "B" position, you can directly tune any
nonscrambled channels on your TV. With the switch in the "A" position, tune your TV to the output of the converter/descrambler box
(usually channel 3 or 4) and use the box to tune scrambled channels.

Note:
This television has an extended tuning range and
can tune most cable channels without using a
cable company supplied converter box. Some cable
companies offer "premium pay channels" in which
the signal is scrambled. Descrambling these signals
for normal viewing requires the use of a descrambler
device which is generally provided by the cable
company.
