[. . . ] 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 PDF "pdfFactory Pro" www. fineprint. com. cn -6- 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. (19) This product may be damaged if it is subject to excessive stresses (such as excessive voltage, current, or temperature). (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. 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. 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). [. . . ] 7. CN10 PHONEJACK AND CN26, CN31 RCA JACKS ARE OPTION TO DVI AUDIO INPUT TERMINALS. 10.
