Warnings and Precautions

• This TV set is designed to operate on AC 110-240 V,
50 / 60 Hz.

• To prevent damage which
might result in electric
shock or fire, do not
expose this TV set to rain
or excessive moisture.
This TV must not be
exposed to dripping or
splashing water, and objects filled with liquid, such as
vases, must not be placed on top of or above the TV.

• DO NOT use this unit near
water. (Near a bath tub,
etc.)

•

Unplug the power cord in
the event of any malfunction
(screen goes blank, no
sound, odd sounds, smoke
or unusual odours coming
from the unit).
Unplug the power cord if
foreign matter or water falls into the unit, or if the unit
is dropped or the cabinet is damaged.

• TAKE CARE NOT to
damage the power cord.

• DO NOT touch the aerial
cable and this unit when
there is lightning.

• DO NOT use if the power
cord or power plug is
damaged, or if the plug
does not fit tightly into the
socket.

• DO NOT touch the power
plug if your hands are wet.

• Turn the power “Off”
before connecting other
electrical equipment.

• Ask your sales outlet to
install the aerial.

• WARNING : HIGH VOLTAGE!!!
Do not remove the rear
cover as live parts are
accessible when it is
removed. There are no
user serviceable parts
inside.

• TV Games / Home Computers
Extended use of TV games or home computers with
any television set can cause a permanent ‘shadow’
on the screen. This type of irreversible LCD panel
damage, can be limited by observing the following
points:

• Reduce the brightness and contrast levels to a

minimum viewing level.

• Do not allow a still picture to be displayed for an

extended period, as this can cause a permanent after­image to remain on the LCD TV screen.

• Examples of still pictures include logos, video games,

computer images, teletext and images displayed in
16:9 mode.

• This type of LCD panel damage, is not an operating

defect, and as such is not covered by the Panasonic
warranty.

• DO NOT use at a voltage
other than indicated.

Warnings and Precautions

• The On / Off switch on this model does not fully
disconnect the TV from the mains supply.
Remove the mains plug
from the wall socket
before connecting or
disconnecting any leads,
or if the TV set is not used
for a prolonged period of
time.

Note:

If the set is not switched off when the TV station stops
transmitting, it will automatically go to Standby mode
after 30 minutes. This function will not operate when
the TV is in AV mode.

• Cabinet and LCD panel care
Remove the mains plug
from the wall socket. The
cabinet and LCD panel
can be cleaned with a soft
cloth moistened with mild
detergent and water.
Do not use solutions
containing benzol or petroleum.

•When ambient temperature is cool, the picture may
take a short time to reach normal brightness, but this
is not a malfunction. (After brief moment, the picture
will have normal brightness.)

• Adequate ventilation is
essential to prevent failure
of electrical components,
we recommend that a gap
of at least 10cm is left all
around this TV set even
when it is placed inside a
cabinet or between shelves.

•Avoid exposing the TV set
to direct sunlight and other
sources of heat. To
prevent fire, never place
any type of candle or
naked flame on top or
near the TV set.

• DO NOT insert foreign
objects (metal or easily
flammable objects).

• DO NOT stand, or place
heavy objects on the unit.
Particular care should be
taken by families with
small children.

• DO NOT place in an
unstable location.

• Place in a safe location.

• DO NOT jolt the unit.

Preparation

• Receiver Location
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.
To insure optimum picture do not position magnetic
equipment (motors, fans, other speakers, etc.) nearby.

• Optional External Equipment
The Audio / Video connection between components
can be made with shielded video and audio cables.
For best performance, we recommend 75 Ω coaxial
aerial cable is used. 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.

• For optimum quality picture
When the LCD is exposed to light from outdoors or
lighting fixtures, high-contrast pictures may not be
displayed clearly. Turn off florescent lamps near the
LCD and place in a location not exposed to outdoor
light.
