Connecting to cable television
This television has an extended tuning range
and can tune most cable channels without using
a cable television converter box. Some cable
television 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 television
company.
For subscribers to basic cable television 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 the television.
For subscribers to scrambled cable television
service
1 If you subscribe to a cable television service
which requires the use of a
converter/descrambler box, connect the
incoming 75 ohm coaxial cable to the
converter/descrambler box.
2 Using another 75 ohm coaxial cable, connect
the output jack of the converter/descrambler
box to the RF IN jack on the television. Follow
the connections shown above.
3 Set the television 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
television service with scrambled premium
channels
If you subscribe to a cable television 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 television company or an
electronics supply store). Follow the connections
shown above. With the switch in the B position,
you can directly tune any nonscrambled
channels on your television. With the switch in
the A position, tune your television to the output
of the converter/descrambler box (usually
channel 3 or 4) and use the
converter/descrambler box to tune scrambled
channels.
Connecting to other equipment
The exact arrangement you use to interconnect
various video and audio components to the
television is dependent on the model and
features of each component. Check the owner's
manual provided with each component for the
location of video and audio inputs and outputs.
The following connection diagrams are offered
as suggestions. You may need to modify them to
accommodate your particular assortment of
components. The diagrams are intended to
show component video and audio
interconnections only.
