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.
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.
