Safety Precautions
WARNING
Set up
Do not place the Plasma TV on sloped or unstable surfaces.
• The Plasma TV may fall off or tip over.
Do not place any objects on top of the Plasma TV.
• If water spills onto the Plasma TV or foreign objects get inside it, a short-circuit may occur which could result in fire or
electric shock. If any foreign objects get inside the Plasma TV, please consult an Authorized Service Center.
Do not cover the ventilation holes.
• Doing so may cause the Plasma TV to overheat, which can cause fire or damage to the Plasma TV.
If using the pedestal, leave a space of 3 15/16” (10 cm) or more at the top, left and right, 2 3/8” (6 cm) or more at the
bottom, and 2 3/4” (7 cm) or more at the rear. If using some other setting-up method, leave a space of 3 15/16” (10 cm)
or more at the top, bottom, left and right, and 3/4” (1.9 cm) or more at the rear.
Avoid installing this product near electronic equipment that easily receives electromagnetic waves.
• It may cause interference in image, sound, etc. In particular, keep video equipment away from this product.
AC Power Supply Cord
The Plasma TV is designed to operate on 120 V AC, 50/60 Hz.
Securely insert the power cord plug as far as it will go.
• If the plug is not fully inserted, heat may be generated which could cause fire. If the plug is damaged or the wall socket
plate is loose, they should not be used.
Do not handle the power cord plug with wet hands.
• Doing so may cause electric shocks.
Do not do anything that might damage the power cable. When disconnecting the power cable, hold the plug, not
the cable.
• Do not make any modifications, place heavy objects on, place near hot objects, heat, bend, twist or forcefully pull the
power cable. Doing so may cause damage to the power cable which can cause fire or electric shock. If damage to the
cable is suspected, have it repaired at an Authorized Service Center.
If the Plasma TV will not be used for a long period of time, unplug the power cord from the wall outlet.
If problems occur during use
If a problem occurs (such as no picture or no sound), or if smoke or an abnormal odor is detected from the Plasma
TV, unplug the power cord immediately.
• Continuous use of the TV under these conditions might cause fire or permanent damage to the unit. Have the TV
evaluated at an Authorized Service Center. Services to the TV by any unauthorized personnel are strongly discouraged
due to its high voltage dangerous nature.
If water or foreign objects get inside the Plasma TV, if the Plasma TV is dropped, or if the cabinet becomes damaged,
disconnect the power cord plug immediately.
• A short may occur, which could cause fire. Contact an Authorized Service Center for any repairs that need to be made.

CAUTION
This Plasma TV is for use only with the following optional accessories. Use with any other type of optional
accessories may cause instability which could result in the possibility of injury.
(All of the following accessories are manufactured by Matsushita Electric Industrial Co., Ltd.)
• Pedestal (included) ............................................. TY-ST42PX20 (TH-42PX20) / TY-ST50PX20 (TH-50PX20)
• Wall-hanging bracket (Vertical) ........................... TY-WK42PV3U
• Wall-hanging bracket (Angled) ............................ TY-WK42PR2U
• Display stand ....................................................... TY-S42PX20U (TH-42PX20) / TY-S50PX20U (TH-50PX20)
Always be sure to ask a qualified technician to carry out set-up.
When using the Plasma TV
Do not bring your hands, face or objects close to the ventilation holes of the Plasma TV.
• Top of the Plasma TV is usually very hot due to the high temperature of exhaust air being released through the ventilation
holes. Burns or personal injuries can happen if any body parts are brought too close. Placing any object near the top of the
TV could also result in heat damages to the object as well as to the TV if its ventilation holes are blocked.
Be sure to disconnect all cables before moving the Plasma TV.
• Moving the TV with its cables attached might damage the cables which, in turn, can cause fire or electric shock.
Disconnect the power plug from the wall outlet as a safety precaution before carrying out any cleaning.
• Electric shocks can result if this is not done.
Clean the power cable regularly to prevent it from becoming dusty.
• Built-up dust on the power cord plug can increase humidity which might damage the insulation and cause fire. Unplug
the cord from the wall outlet and clean it with a dry cloth.
This Plasma TV radiates infrared rays, therefore it may affect other infrared communication equipment.
Install your infrared sensor in a place away from direct or reflected light from your Plasma TV.
Cleaning and maintenance
The front of the display panel has been specially treated. Wipe the panel surface gently using only a cleaning cloth
or a soft, lint-free cloth.
• If the surface is particularly dirty, soak a soft, lint-free cloth in a weak detergent solution and then wring the cloth to
remove excess liquid. Use this cloth to wipe the surface of the display panel, then wipe it evenly with a dry cloth, of the
same type, until the surface is dry.
• Do not scratch or hit the surface of the panel with fingernails or other hard objects. Furthermore, avoid contact with volatile
substances such as insect sprays, solvents and thinner, otherwise the quality of the surface may be adversely affected.
If the cabinet becomes dirty, wipe it with a soft, dry cloth.
• If the cabinet is particularly dirty, soak the cloth in a weak detergent solution and then wring the cloth dry. Use this cloth
to wipe the cabinet, and then wipe it dry with a dry cloth.
• Do not allow any detergent to come into direct contact with the surface of the Plasma TV.
If water droplets get inside the unit, operating problems may result.
• Avoid contact with volatile substances such as insect sprays, solvents and thinner, otherwise the quality of the cabinet
surface may be adversely affected or the coating may peel off. Furthermore, do not leave it for long periods in contact
with articles made from rubber or PVC.
Note:
Do not allow a still picture to be displayed for an extended period, as this can cause a permanent after-image to remain
on the Plasma TV.
Examples of still pictures include logos, video games, computer images, teletext and images displayed in 4:3 mode.
Safety Precautions 
						

							9
     Precaution on battery use
Incorrect installation can cause battery leakage and corrosion that
will damage the remote control transmitter.
Observe the following precautions:
1. Batteries should always be replaced as a pair. Always use new
batteries when replacing the old set.
2. Do not combine a used battery with a new one.
3. Do not mix battery types (example: “Zinc Carbon” with “Alkaline”).
4. Do not attempt to charge, short-circuit, disassemble, heat or burn
used batteries.
5. Battery replacement is necessary when remote control acts
sporadically or stops operating the TV set.
Requires two AA batteries.
1. Turn the Transmitter face down.
Remove top cover by pressing
down on marking and sliding cover
off in the direction indicated.2. Install the batteries as shown in the
battery compartment. (Polarity + or
– must match the markings in the
compartment).3. Replace the cover and slide in
reverse until the lock snaps.
Two AA size
For frequent remote control users, replace old
batteries with alkaline batteries for longer life.
Helpful Hints:
The Video/Audio connection between components can be made with shielded video and audio cables. For best performance,
video cables should utilize 75 ohm coaxial shielded wire. Cables are available from your dealer or electronic supply store.
Before you purchase any cables, be sure you know what type of output and input connectors your various components
require. Also determine the length of cable you will need.
Installation
Receiver Location
This unit is intended to be used with an optional stand or entertainment center. Consult your dealer for available options. Locate for
comfortable viewing. Avoid placing where sunlight or other bright light (including reflections) will fall on the screen.
Use of some types of fluorescent lighting can reduce remote control transmitter range.
Adequate ventilation is essential to prevent internal component failure. Keep away from areas of excessive heat or moisture.
Optional External Equipment
Whenever you remove the batteries, you may
need to reset the remote control infrared
codes. We recommend that you record the code
on page 59, prior to setting up the remote control.
