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.
ANTENNA/CATV CONNECTIONS
Separate VHF/UHF Antennas
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 left. 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 left. 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.
