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) To prevent electric shock, ensure the grounding pin on the AC cord power plug is securely connected.

2 Warning
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.
(All of the following accessories are manufactured by Panasonic Corporation.)
Remote Control Kit.................................... TY-RM50VW
Cover-frame Kit........................................TY-CF47VW5
Always be sure to ask a qualified 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.
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 is spills onto the Display 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 Display, please consult your local Panasonic dealer.
Transport only in upright position!
Transporting the unit with its display panel facing upright or downward may cause damage to the internal
circuitry.
Ventilation should not be impeded by covering the ventilation openings with items such as newspapers,
table cloths and curtains.
For sufficient ventilation;
Leave a space of 3-15/16” (10 cm) or more at the top, bottom, left, and right to the outermost circumference of
this Display.
Leave a space of 1-31/32” (5 cm) or more at the rear.
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 wall hanging bracket
that conforms to VESA standards (VESA 400 × 400) must be used.
When using the LCD Display
The Display is designed to operate on 220 - 240 V AC, 50/60 Hz.
Do not cover the ventilation holes.
Doing so may cause the Display to overheat, which can cause fire or damage to the Display.
Do not stick any foreign objects into the Display.
Do not insert any metal or flammable objects into the ventilations holes or drop them onto the Display, as doing
so can cause fire or electric shock.
Do not remove the cover or modify it in any way.
High voltages which can cause severe electric shocks are present inside the Display. For any inspection,
adjustment and repair work, please contact your local Panasonic dealer.

Ensure that the mains plug is easily accessible.
An apparatus with CLASS I construction shall be connected to a mains socket outlet with a protective
earthing connection.
Do not use any power supply cord other than that provided with this unit.
Doing so may cause fire or electric shocks.
Securely insert the power supply 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 is loose, they shall not be used.
Do not handle the power supply plug with wet hands.
Doing so may cause electric shocks.
Do not do anything that may damage the power cable. When disconnecting the power cable, pull on the
plug body, not the cable.
Do not damage the cable, make any modifications to it, place heavy objects on top of it, heat it, place it near any
hot objects, twist it, bend it excessively or pull it. To do so may cause fire and electric shock. If the power cable is
damaged, have it repaired at your local Panasonic dealer.
If the Display is not going to be used for any prolonged length of time, unplug the power supply plug from
the wall outlet.
To prevent the spread of fire, keep candles or other open flames away from this product at all times.
If problems occur during use
If a problem occurs (such as no picture or no sound), or if smoke or an abnormal odour starts to come out
from the Display, immediately unplug the power supply plug from the wall outlet.
If you continue to use the Display in this condition, fire or electric shock could result. After checking that the
smoke has stopped, contact your local Panasonic dealer so that the necessary repairs can be made. Repairing the
Display yourself is extremely dangerous, and shall never be done.
If water or foreign objects get inside the Display, if the Display is dropped, or if the cabinet becomes
damages, disconnect the power supply plug immediately.
A short circuit may occur, which could cause fire. Contact your local Panasonic dealer for any repairs that need
to be made.

3.2. Applicable signals
PC signals:
SDTV Resolution:
Option signals (OPTION):
• The PC text quality is optimum in HD 1080 mode (1920 x 1080, 60Hz).
• Your PC display screen might appear different depending on the manufacture (and your particular version of
Windows).
• Check your PC instruction book for information about connecting your PC to a monitor.
• If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 31.5KHz (horizontal). In some
cases, abnormal signals (such as stripes) might appear on the screen when the PC power is turned off (or if the
PC is disconnected). If so, press the [INPUT] button to enter the option mode. Also, make sure that the PC is
connected.
• When horizontal synchronous signals seem irregular in RGB mode, check PC power saving mode or cable
connections.
• The display settings table complies to the IBM/VESA standards, and based on the analog input.
• The DVI support mode is regarded as same to the PC support mode.
• The best timing for the vertical frequency to each mode is 60Hz.
