Miscellaneous caution matters
(1) This product uses highly integrated semiconductor parts. Since these parts are fragile to electrostatic
charges, earth bands should be used for handling. The product should be handled where measures have
been taken against electrostatic charges.
(2) For this product, the PDP modules and the PWBs are repaired by replacement in a unit. Therefore, the
units of the PDP modules and the PWBs must not be repaired or disassembled. Otherwise, the validity of
warranty will be lost.
(3) If this product is used for the fixed character display or the like as in the case of a character display board,
a phenomenon of burning (not warranted) will occur. Burning is a phenomenon that the unevenness in the
brightness is caused in the display. In such a case, the brightness in the section where the integrated
display time is longer becomes lower than the brightness in another section where the integrated display
time is shorter. This phenomenon is in proportion to the integrated display time and the brightness. For this
reason, to relieve this difficulty during servicing, do not use any still picture, but use a display by motion
pictures of a video or the like. In addition, use “FULL” for the screen mode and avoid using any display by
“NORMAL”, “TRUE”, or MULTI SCREEN like side by side etc. If it is necessary to use only a still picture for
unavoidable reasons, use a burning relief function such as “PLE LOCK”, “ORBITER”, “SCREEN WIPER”,
etc.
(4) When a PDP module is operated after a long time of storage, it may encounter a difficulty like a failure in
displaying a screen or unstability according to the condition of storage. In such a case, the PDP module
should be incorporated in the product and aging treatment should be carried out for about two hours (all
screen display).
(5) Sulfides will deteriorate the PDP module and this is a cause of malfunction. Therefore, it is absolutely
prohibited to put any vulcanized rubber or a material containing sulfur in the vicinity of the PDP module.
(6) When taking out a PDP module from the maintenance package box, do it slowly so that the panel surface

given in the instruction manuals, etc., must be
observed, without fail.
• Do not give shocks and vibration.
• The panel surface (display plane) of the filter and the PDP module is made of glass. If any
shocks or vibration is applied, it may be broken and the scattered glass chips will be a
cause of injury.
• Do not put anything.
• Do not put anything on the product. Otherwise, this can be a cause of injury as a result of
falling down or dropping caused by imbalance.
• Transportation must be done by enough personnel.
• The product is heavy. In the case of transportation, unpacking, or packing, more than two
persons should do it (four persons for a product of 50-inch or larger) by supporting the top
and the bottom of the product.
