This television has an extended tuning range and can tune most
CATV channels without using a CATV company supplied
converter box. Some CATV 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 CATV company.
For subscribers to basic CATV 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 CATV service
If you subscribe to a CATV 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.
