• 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 ANT. terminal.
• 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 to channel 3
or 4, typically one of these channels is used. If this is unknown, consult your cable TV company.) For more
specific 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.
Please note: An RF switch provided with two inputs (A and B) is required (not supplied).
“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.
CABLE TV (CATV) CONNECTION
■ Using the AC Adapter
• Although the AC adapter may become warm during use, this is not a malfunction.
• Do not wrap or cover the AC adapter with a blanket or similar covering. This can cause a malfunction or accident.
• Do not attempt to disassemble or modify the AC adapter. The insides of the AC adapter contain high-voltage components
that can result in the risk of electrical shock.
• When you insert the AC adapter plug into the POWER INPUT terminal of the main unit, make sure that it is fitted firmly.
• Once the AC adapter plug is plugged in, be sure that it is held by the cable holder and fixed neatly.

• Use a commercially available AC plug adapter, if necessary, depending on the design of the wall outlet.
