the following precautions carefully before using the product.

■ Read instructions—All operating instructions must be read and understood before the product is
operated.

■ Keep this manual in a safe place—These safety and operating instructions must be kept in a
safe place for future reference.

■ Observe warnings—All warnings on the product and in the instructions must be observed
closely.

■ Follow instructions—All operating instructions must be followed.

■ Attachments—Do not use attachments not recommended by the manufacturer. Use of inad-

equate attachments can result in accidents.

■ Power source—This product must operate on a power source specified on the specification
label. If you are not sure of the type of power supply used in your home, consult your dealer or
local power company. For units designed to operate on batteries or another power source, refer

■ Repair—If any of the following conditions occurs, unplug the power cord from the AC outlet, and
request a qualified service person to perform repairs.
a.When the power cord or plug is damaged.
b.When a liquid was spilled on the product or when objects have fallen into the product.
c. When the product has been exposed to rain or water.
d.When the product does not operate properly as described in the operating instructions.

Do not touch the controls other than those described in the operating instructions. Improper

adjustment of controls not described in the instructions can cause damage, which often

requires extensive adjustment work by a qualified technician.
e.When the product has been dropped or damaged.
f. When the product displays an abnormal condition. Any noticeable abnormality in the product

indicates that the product needs servicing.

■ Replacement parts—In case the product needs replacement parts, make sure that the service
person uses replacement parts specified by the manufacturer, or those with the same character­istics and performance as the original parts. Use of unauthorized parts can result in fire, electric
shock and/or other danger.

■ Safety checks—Upon completion of service or repair work, request the service technician to
perform safety checks to ensure that the product is in proper operating condition.

■ Wall or ceiling mounting—When mounting the product on a wall or ceiling, be sure to install the
product according to the method recommended by the manufacturer.

■ Polarization—This AC adapter may be equipped with a polarized alternating current line plug (a
plug having one blade wider than the other). This plug will fit into the power outlet only one way.
This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.

IMPORTANT SAFETY PRECAUTIONS (Continued)

■ If an outside antenna is connected to the television equipment, be sure the antenna system is
grounded so as to provide some protection against voltage surges and built-up static charges.
Section 810 of the National Electrical Code provides information with respect to proper grounding
of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit,
size of grounding conductors, Iocation of antenna-discharge unit, connection to grounding elec­trodes, and requirements for the grounding electrode.

■ For added protection for this television equipment during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and
disconnect the antenna. This will prevent damage to the
equipment due to lightning and power-line surges.

■ An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system, extreme
care should be taken to keep from touching such power
lines or circuits as contact with them might be fatal.

Antenna Connection

CABLE TV (CATV) CONNECTION

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

Antenna Connection (Continued)

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).

75-ohm coaxial cable (round)

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).

300-ohm twin-lead cable (flat)

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.
