Cable (CATV)/satellite connections

This 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
company.

FOR SUBSCRIBERS TO BASIC CABLE TV SERVICE

For basic cable service not requiring a converter/descrambler box,
connect the CATV 75 ohm coaxial cable to the VHF/UHF jack on the
rear of the TV.

FOR SUBSCRIBERS TO SCRAMBLED CABLE TV SERVICE OR SATELLITE

If you subscribe to a satellite service or 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 cable, connect the output of the converter/descrambler or satellite box to the antenna jack
on the TV. Follow the connections shown below. Set the TV/VCR to the output channel of the
converter/descrambler or satellite box (usually 3 or 4) and use the converter/descrambler or satellite box to
select channels.

FOR SUBSCRIBERS TO UNSCRAMBLED BASIC CABLE TV SERVICE

WITH SCRAMBLED PREMIUM CHANNELS

If you subscribe to a satellite service or 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 company or an electronic 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.
