IMPORTANT SAFETY PRECAUTIONS (Continued)
•
If
an
outside antenna is connected to the television equipment, be sure the antenna systemisgrounded soasto
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, location of antenna-discharge unit, connection
to grounding electrodes, and requirements for the grounding electrode.

Preparation
Before using the LCDTVset for the first time, install the two "AAA" size batteries supplied in the remote control. When the
batteries become depleted and the remote control fails to operate, replace the batteries with new "AAA" size batteries.
1 Open the battery cover.
• Slide the cover while
pressing the
(T)
part.
2 Insert two "AAA" size batteries.
• Place batteries with their
terminals corresponding
to the (+) and
(-)
indications in the battery
compartment.
3 Close the battery cover.
• Engaging the lower
claw with the remote
control, close the
cover.
Precautions regarding batteries
• Improper use of batteries can result in a leakage of chemicals and/or explosion. Be sure to follow the instructions below.
Place batteries
wit~
their terminals corresponding to the (+) and
(-)
indications.
Different typesofbatteries have different characteristics. Do not mix batteries of different types.
Do not mix old and
new
batteries. Mixing old and new batteries can shorten the life of new batteries and/or cause old
batteries to leak chemicals.
Remove batteries as soon as they are depleted. Chemicals that leak from batteries can cause a rash. If chemical
leakage is found, wipe it off with a cloth.
The
batteries supplied with the LCDTVset may have a shorter operating time due to storage conditions.
If the remote control is not to be used for an extended period of time, remove the batteries from the remote control.
8@
• Use the remote controlbypointing it towards the remote sensor
window of the main unit. Objects between the remote control and
sensor window may prevent proper operation.
Cautions regarding use of remote control
• Do not apply shock to the remote control.Inaddition, do not
expose the remote control to liquids, and do not place it in an area
with high humidity.
• Do not install or place the remote control under direct sunlight. The
heat may cause deformation of the unit.
• The remote control may not
work
properlyifthe remote sensor
window is under direct sunlightorstrong lighting.Insuch a case,
change the angle of the lighting or main unit, or operate the remote
control closer to the remote sensor window.

Preparation (Continued)
• 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).
~
F-type connector
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 ANT. (Antenna terminal) on the rear of the main unit.

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. (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:
AnRFswitch provided with two inputs (A andB)is required (not supplied).
"A" position
on
theRFswitch (not supplied):
You
can view all unscrambled channels by using the TV's channel keys.
"B" position

can view the scrambled channels via the converter/descrambler by
using the converter's channel keys.

• Although theACadapter may become warm during use, thisisnot 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 theACadapter. 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 itisfitted firmly.
• Once the
AC
adapter plugisplugged
in,
be sure that itisheld by the cable holder and fixed neatly.
