(10) In order to protect static electricity due to C-MOS circuitry of
the Drive part, wear a wrist band to protect static electricity
when handling.
(11) If cleaning the Panel, wipe it with a soft cloth moistened with
water or a neutral detergent and squeezed, being careful not
to touch the connector part of the Panel. And don't use
chemical materials like thinner or benzene.
(12) If this product is used as a display board to display a static
image, "image sticking" occurs. This means that the luminance
of areas of the display that remain lit for a long time drops
compared with luminance of areas that are lit for a shorter
time, causing uneven luminance across the display.
The degree to which this occurs is in proportion to the
luminance at which the display is used. To prevent this
phenomenon, therefore, avoid static images as much as
possible and design your system so that it is used at a low
luminance, by reducing signal level difference between bright
area and less bright area through signal processing.
(13) Because PDP Module emits heat from the Glass Panel part
and the Drive circuitry, the environmental temperature must
not be over 40°C.
The temperature of the Glass Panel part is especially high
owing to heat from internal Drive circuitry. And because the
PDP Module is driven by high voltage, it must avoid
conductive materials.
(14) If inserting components or circuit board in order to repair, be
sure to fix a lead line to the connector before soldering.
(15) If inserting high-power resistor(metal-oxide film resistor or
metal film resistor) in order to repair, insert it as 10mm away
as from a board.
(16) During repairs, high voltage or high temperature components
must be put away from a lead line.
(17) This is a Cold Chassis but you had better use a cold
transformer for safety during repairs. If repairing electricity
source part, you must use the cold transformer.
(18) Do not place an object on the glass surface of the display.
The glass may break or be scratched.
(19) This product may be damaged if it is subject to excessive
stresses (such as excessive voltage, current, or temperature).
The absolute maximum ratings specify the limits of these
stresses.
(20) The recommended operating conditions are conditions in
which the normal operation of this product is guaranteed. All
the rated values of the electrical specifications are guaranteed
within these conditions.
Always use the product within the range of the recommended
operating conditions. Otherwise, the reliability of the product
may be degraded.
(21) This product has a glass display surface. Design your
system so that excessive shock and load are not applied to
the glass. Exercise care that the vent at the corner of the glass
panel is not damaged.
If the glass panel or vent is damaged, the product is
inoperable.
(22) Do not cover or wrap the product with a cloth or other
covering while power is supplied to the product.
(23) Before turning on power to the product, check the wiring of
the product and confirm that the supply voltage is within the
rated voltage range. If the wiring is wrong or if a voltage
outside the rated range is applied, the product may
malfunction or be damaged.
(24) Do not store this product in a location where temperature
and humidity are high. This may cause the product to
malfunction. Because this product uses a discharge
phenomenon, it may take time to light (operation may be
delayed) when the product is used after it has been stored for
a long time. In this case, it is recommended to light all cells for
about 2 hours (aging).
(25) This product is made from various materials such as glass,
metal, and plastic. When discarding it, be sure to contact a
professional waste disposal operator.
(26) If faults occur due to arbitrary modification or disassembly,
LG Electronics is not responsible for function, quality or other
items.
(27) Use of the product with a combination of parameters,
conditions, or logic not specified in the specifications of this
product is not guaranteed. If intending to use the product in
such a way, be sure to consult LGE in advance.
(28) Within the warranty period, general faults that occur due to
defects in components such as ICs will be rectified by LGE
without charge. However, IMAGE STICKING due to
misapplying the above (12) provision is not included in the
warranty. Repairs due to the other faults may be charged for
depending on responsibility for the faults.
