(2) it s recommended t o assemble or to install a module into the users system in clean working areas. the dust and oil may c ause electrical short or worsen the polarizer. (3) don t apply pressure or impulse to the module to prevent the damage of lcd panel and backlight. (4) always follow the correct power - on sequence when the lcd module is turned on . this can prevent the d amage and latch - up of the cmos lsi chips. (5) do not plug in or pull out the i/f connector while the module is in operati on . (6) do not disassemble the module. (7) use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is ve ry soft and easily scratched. (8) m oisture can easily penetrate into lcd module and may cause the damage during operation. (9) high temperature or humidity may deteriorate the performance of lcd module. please store lcd module in the specified storage c onditions. (10) when ambient temperature is lower than 10oc , the display quality might be reduced. for example, the response time will become slow . 15 .2 s afety precautions (1) if the liquid crystal material leaks from the panel, it should be kept away fro m the eyes or mouth. in case of contact with hands, skin or clothes, it has to be washed away thoroughly with soap. (2) after the modules end of life, it is not harmful in case of normal operation and storage. 15.3 terms of warrant (1) acceptance inspect ion period the period is within one month after the arrival of contracted commodity at the buyer s factory site. (2) applicable warrant period the period is within twelve months since the date of shipping out under normal using and storage co nditions.
