Cable TV connections

Your TV has an extended tuning range and can tune most cable channels without using a Cable TV converter box. Some Cable TV 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 TV company.

For subscribers to basic cable TV service.

For basic cable service not requiring a converter/ descrambler box, connect the 75 ohm coaxial cable directly to the RF IN jack on the back of your TV.

75 ohm coaxial cable

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 RF IN Jack on your TV. Set your 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 basic 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). 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, you can 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.
