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.
