Safety Precautions
(4) This product contains glass. The glass may break, causing injuries, if shock, vibration, heat, or
distortion is applied to the product.
(5) The temperature of the glass of the display may rise to 80 C or more depending on the conditions
of use. If you touch the glass inadvertently, you may be burned.
(6) If glass surface of the display breaks or is scratched, do not touch the broken pieces or the
scratches with bare hands. You may be injured.
(7) PDP Module requires to be handled with care not to be touched with metal or hard materials, and
must not be stressed by heat or mechanical impact.
(8) There are some exposed components on the rear panel of this product. Touching these components
may cause an electric shock.
(9) When moving the product, be sure to turn off the power and disconnect all the cables. While
moving the product, watch your step. The product may be dropped or all, leading to injuries of
electric shock.
(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.
