Safety Precautions

CAUTION

This LCD Display 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.

• Pedestal ................................................... TY-ST42P50

Always be sure to ask a qualifi ed technician to carry out set-up.

Small parts can present choking hazard if accidentally swallowed. Keep small parts away from young children. Discard
unneeded small parts and other objects, including packaging materials and plastic bags/sheets to prevent them from being
played with by young children, creating the potential risk of suffocation.

(All of the following accessories are manufactured by Panasonic Corporation.)

When using the LCD Display

Do not bring your hands, face or objects close to the
ventilation holes of the Display.

•

Top of the Display 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 display
could also result in heat damages to the object as well as to
the Display if its ventilation holes are blocked.

Be sure to disconnect all cables before moving the
Display.

•

Moving the Display with its cables attached might damage
the cables which, in turn, can cause fi re 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 fi re. Unplug
the cord from the wall outlet and clean it with a dry cloth.

Note:

Image retention may occur. If you display a still picture for an
extended period, the image might remain on the screen. However,
it will disappear after a while.

Safety Precautions

WARNING

Setup

Do not place the Display on sloped or unstable
surfaces, and ensure that the Display does not hang
over the edge of the base.

• The Display may fall off or tip over.

Do not place any objects on top of the Display.

• If water spills onto the Display or foreign objects get
inside it, a short-circuit may occur which could result in
fi re or electric shock. If any foreign objects get inside the
Display, please consult an Authorized Service Center.

Do not cover the ventilation holes.

• Doing so may cause the Display to overheat, which can
cause fi re or damage to the Display.

Transport only in upright position!

• Transporting the unit with its display panel facing upright
or downward may cause damage to the internal circuitry.

For suffi cient ventilation;
Leave a space of 3
and right, and 1 31/32” (5 cm) or more at the rear, and
also keep the space between the bottom of the display
and the fl oor surface.

Cautions for Wall Installation

• Wall installation should be performed by an installation
professional. Installing the Display incorrectly may lead to an
accident that results in death or serious injury. Furthermore,
when installing on a wall, a UL standard certifi ed wall
hanging bracket (VESA 400 × 400) must be used.

• When installing the Display vertically, be sure to install
the power indicator onto the bottom of the Display.

An apparatus with CLASS I construction shall be
connected to a mains socket outlet with a protective
earthing connection.

Do not install the product to a place where the
product is exposed to direct sunlight.

• If the screen is exposed to direct sunlight, the liquid crystal
panel may have adverse effect.

15/16” (10 cm) or more at the top, left

AC Power Supply Cord

The Display is designed to operate on 110 - 127 V AC, 50/60 Hz.
Ensure that the mains plug is easily accessible.

Do not use any power supply cord other than that
provided with this unit.

• Doing so may cause fi re or electric shocks.

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 fi re. 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 modifi cations, 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 fi re or
electric shock. If damage to the cable is suspected,
have it repaired at an Authorized Service Center.

If the Display 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
Display, unplug the power cord immediately.

•

Continuous use of the Display under these conditions might
cause fi re or permanent damage to the unit. Have the
Display evaluated at an Authorized Service Center. Services
to the Display by any unauthorized personnel are strongly
discouraged due to its high voltage dangerous nature.

If water or foreign objects get inside the Display, if the
Display is dropped, or if the cabinet becomes damaged,
disconnect the power cord plug immediately.

• A short may occur, which could cause fi re. Contact an
Authorized Service Center for any repairs that need to
be made.

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, wipe with a soft, lint-free cloth which has been soaked in pure water or water in which neutral

•
detergent has been diluted 100 times, and 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 fi ngernails or other hard objects, otherwise the surface may become
damaged. 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 water to which a small amount of neutral detergent has been added
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 Display. 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.

Usage of a chemical cloth

• Do not use a chemical cloth for the panel surface.

• Follow the instructions for the chemical cloth to use it for the cabinet.
