CAUTION
THIS LCD COLOR TELEVISION EMPLOYS A LASER SYSTEM.
TO ENSURE PROPER USE OF THIS PRODUCT, PLEASE READ THIS SERVICE MANUAL CARE-
FULLY AND RETAIN FOR FUTURE REFERENCE. SHOULD THE UNIT REQUIRE MAINTENANCE,
CONTACT AN AUTHORIZED SERVICE LOCATION-SEE SERVICE PROCEDURE.
USE OF CONTROLS, ADJUSTMENTS OR THE PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS LASER RADIATION EXPOSURE.
TO PREVENT DIRECT EXPOSURE TO LASER BEAM, DO NOT TRY TO OPEN THE ENCLOSURE.
VISIBLE LASER RADIATION MAY BE PRESENT WHEN THE ENCLOSURE IS OPENED. DO NOT
STARE INTO BEAM.
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is received at the
time of repair, the life of the product may be shortened.
Please perform the following measure against static electricity, be careful of destruction of a laser diode
at the time of repair.
• Place the unit on a workstation equipped to protect against static electricity, such as conductive mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.
Location of the required Marking
The rating sheet and the safety caution are on the rear of the unit.
CERTIFICATION: COMPLIES WITH FDA

IMPORTANT SAFEGUARDS
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
10) Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
11) Only use attachments/accessories specified by the manufacturer.
12) Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
13) Unplug this apparatus during lightning storms or when unused for long periods
of time.
14) Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
15) Apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such a vases,
shall be placed on the apparatus.
16) 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.
17) Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock.
18) Do not push objects through any openings in this unit, as they may touch dangerous voltage points or short
out parts that could result in fire or electric shock. Never spill or spray any type of liquid into the unit.

19) If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is
grounded to provide some protection against voltage surges and built-up static charges, Section 810 of
the National Electrical Code, ANSI/NFPA 70, 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 ground-
ing conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements
for the grounding electrode.
20) When replacement parts are required, be sure the service technician uses replacement parts specified by
the manufacturer or those that have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock or other hazards.
21) Upon completion of any service or repairs to this unit, ask the service technician to perform safety checks
to determine that the unit is in proper operating condition.
22) Keep your fingers clear of the disc slot as it is closing. It may cause injury.
23) When you connect the product to other equipment, turn off the power and unplug all of the equipment
from the wall outlet. Failure to do so may cause an electric shock and serious personal injury. Read the
owner's manual of the other equipment carefully and follow the instructions when making any connec-
tions.
24) Reduce the volume to the minimum level before you turn on the product. Otherwise, sudden high volume
sound may cause hearing or speaker damage.

HOWTO HANDLETHE LCD PANEL
• Do not press hard or jolt the LCD panel. It may cause the LCD panel glass to break and injury may occur.
• If the LCD panel is broken, make absolutely sure that you do not touch the liquid in the panel.This may
cause skin inflammation.
If the liquid gets in your mouth, immediately gargle and consult with your doctor. Also, if the liquid gets in
your eyes or touches your skin, consult with your doctor after rinsing for at least 15 minutes or longer in clean
water.
CONDENSATION
Moisture will form in the operating section of the player if the player is brought from cool surroundings into a
warm room or if the temperature of the room rises suddenly.When this happens, player's performance will
be impaired.
To prevent this, let the player stand in its new surroundings for about an hour before switching it on, or
make sure that the room temperature rises gradually.
Condensation may also form during the summer if the player is exposed to the breeze from an air condi-
tioner. In such cases, change the location of the player.
25) Do not allow the product to output distorted sound for an extended period of time. It may cause speaker
overheating and fire.
26) When you use the headphones, keep the volume at a moderate level. If you use the headphones continu-
ously with high volume sound, it may cause hearing damage.
27) Do not look into the opening of the disc slot or ventilation opening of the product to see the source of the
laser beam. It may cause eye damage.
28) Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause serious
personal injury and product malfunction.
29) This reminder is provided to call the cable TV system installer's attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be con-
nected to the grounding system of the building, as close to the point of cable entry as practical.

PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.
(Please refer to figures.)
Caution:
Pb free solder has a higher melting point than standard solder;
Typically the melting point is 86°F~104°F(30°C~40°C) higher.
Please use a soldering iron with temperature control and adjust it to 650°F ± 20°F (350°C ± 10°C).
In case of using high temperature soldering iron, please be careful not to heat too long.
Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).
All products with the printed circuit board with PbF printing must be serviced with lead free solder.
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Distinction of PbF PCB:
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.
