Cable TV connections
For basic Cable TV service not requiring a Converter/Descrambler box, connect the
75 ohm Coaxial Cable directly to the Antenna Jack on the back of the TV.
For subscribers to scrambled Cable TV service
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 below. Set the TV to the output channel of the Converter/Descrambler
box (usually channel 3 or 4) and use the Converter/Descrambler box to select channels.
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 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 Converter/Descrambler box to tune scrambled channels.
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.
