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

If you subscribe to a Cable TV service which requires the use of a Converter/Descrambler box, connect the
incoming 75 ohm Coaxial Cable to the Converter/Descrambler box. Using another 75 ohm Coaxial Cable, connect
the output jack of the Converter/Descrambler box to the Antenna Jack on the TV. Follow the connections shown

For subscribers to unscrambled Cable TV service with scrambled premium channels
If you subscribe to a Cable TV service in which basic channels are unscrambled and premium channels require
the use of a Converter/Descrambler box, you may wish to use a signal Splitter and an A/B Switch box (available
from the Cable TV company or an electronics supply store). Follow the connections shown below. With the switch
in the "B" position, you can directly tune any non-scrambled 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 Converter/
Descrambler box to tune scrambled channels.
