Cable with a Cable Box that Descrambles Some (But Not All) Channels
To complete this connection you will need a two-way splitter, an RF (A/B) switch, and four coaxial
cables (which you can buy from your Samsung dealer or any electronics store).
Find and disconnect the cable that is
1
connected to the ANTENNA IN terminal
of your Splitter. This terminal might
be labeled "ANT IN", "VHF IN" or
simply, "IN". Connect this cable to a
two-way splitter.
Connect a coaxial cable between an
2
OUT terminal of the splitter and the
IN terminal of the Cable box.
Connect a coaxial cable between the
3
ANTENNA OUT terminal of the Cable
box and the B-IN terminal of the RF
(A/B) switch.
Connect a coaxial cable between the
4
other OUT terminal of the Cable box
and the A-IN terminal of the RF (A/B)
switch.
Connect the last coaxial cable between
5
the OUT terminal of the RF (A/B)
switch and the ANT 1 IN (CABLE IN)
on the TV.
After you've made this connection, set the A/B switch to the "A" position for normal viewing.
Set the A/B switch to the "B" position to view scrambled channels. (When you set the A/B switch to
"B", you will need to tune your Set-Top Box to the Cable box's output channel, which is usually
channel 3 or 4.)
