・A 75 ohm coaxial cable connector is built into the set for easy hookup. When connecting the 75 ohm coaxial 

cable to the set, screw the 75 ohm cable to the COAXIAL CABLE CONNECTOR.
・Some cable TV companies offer “premium pay channels”. Since the signals of these premium pay channels 

are scrambled, a cable TV converter/ descrambler is generally provided to the subscriber by the cable TV 

company. This converter/ descrambler is necessary for normal viewing of the scrambled channels. (Set your 

TV on channel 3 or 4. Typically one of these channels is used. If channel is unknown, consult your cable TV 

company.) For more specifi c instructions on installing cable TV, consult your cable TV company.

One possible method of utilizing the converter/ descrambler provided by your cable TV company is explained 

below.

    

    "A" position on the RF switch (not supplied): You can view all unscrambled channels by using the TV's 

channel keys.

    "B" position on the RF switch (not supplied): You can view the scrambled channels via the converter/

descrambler by using the converter's channel keys.
