CABLE TV (CATV) CONNECTION
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. 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).

ANTENNAS
The antenna requirements for good color television reception are more important than those for black & white
television reception. For this reason, a good quality outdoor antenna is strongly recommended.
The following is a brief explanation of the type of connections that are provided with the various antenna systems.
1. A 75-ohm system is generally a round cable with F-type connector that can easily
be attached to a terminal without tools (not supplied).
2. A 300-ohm system is a flat "twin-lead" cable that can be attached to a 75-ohm
terminal through a 300-75-ohm adapter (not supplied).
OUTDOOR ANTENNA CONNECTION
Use one of the following two diagrams if you connect an outdoor
antenna.
A: Using a VHF/UHF combination outdoor antenna.
B: Using separate VHF and/or UHF outdoor antennas.
Connect the outdoor antenna cable lead-in to the ANT. terminal
on the rear of the TV set.
