your TV.
• If your antenna cable has a 300 ohm connector, connect the cable to a 300-75 ohm adapter (not

to the coaxial jack on the back of your TV.
Connecting cable TV
Your TV has a 75 ohm jack for connecting cable TV .Some cable TV providers scramble the signals
for "premium" (pay) channels. To view these channels, you need a converter/descrambler box.If you do
not have a converter/descrambler box,you can connect your cable TV directly to your TV. If you have a
converter/descrambler box, you can connect your cable TV using an RF switch (not supplied). For more
information about connecting a converter/descrambler box, contact your cable TV provider.
To connect cable TV without a converter/descrambler box:
1 Connect one end of a 75 ohm cable to the coaxial jack on the back of your TV.
2 Connect the other end of the cable to the cable TV wall outlet.
To connect cable TV with a converter/descrambler box:
• Use the following illustration to connect a converter/descrambler box. (The RF switch and the signal
splitter are not provided.) Set the RF switch to the A position to watch unscrambled channels controlled
by your TV
remote control. Set the RF switch to the B position to watch scrambled channels controlled by the
