(b) because the inverter uses high voltages, it sho uld be disconnected from power source before it is assembled or disassembled. (c) refrain from strong mechanical shock and / or a ny force to the module. in addition to damage, it may cause improper operat ion or damage to the module and ccft back light. (d) note that polarizer films are very fragile and could be damaged easily. do not press or scratch the surface harder than a h b pencil lead. (e) wipe off water droplets or oil immediately. if you leave the droplets for a long time, staining or discoloration may occur. (f) if the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth. (g) desirable cleaners are water, ipa (isopropyl al cohol) or hexane. do not use ketone type materials (ex. acetone), eth yl alcohol, toluene, ethyl acid or methyl chloride. it might cause permanent damage to the polarizer due to chemical reaction. (h) if the liquid crystal material leaks from the p anel, it should be kept away from the eyes or mouth . in case of contact with ha nds, legs or clothes, it must be washed away with soap thoroughly. (i) protect the module from static, or the cmos gat e array ic would be damaged. (j) use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (k) do not disassemble the module. (l) do not pull or fold the lamp wire. (m) do not adjust the variable resistor located on the module. (n) protection film for polarizer on the module sho uld be slowly peeled off just before use so that the electrostatic charge can be minimized. (o) pins of i/f connector should not be touched dir ectly with bare hands. 11. general precautions 11.1 handling www..net www..net

(b) do not store the tft-lcd module in direct sunli ght. (c) the module should be stored in a dark place. it is prohibited to apply sunlight or fluorescent light in storing. 11.3 operation (a) do not connect or disconnect the module in the "power on" condition. (b) power supply should always be turned on/off by the item 6.3 "power on/off sequence" (c) module has high frequency circuits. sufficient suppression to the electromagnetic interference should be done by system manufacturers . grounding and shielding methods may be important to minimize the interferen ce. (d) the cable between the back light connector and its inverter power supply should be connected directly with a minimized length. a lo nger cable between the back light and the inverter may cause lower lum inance of lamp(ccft) and may require higher startup voltage (vs). 11.4 operation condition guide (a) the lcd product should be operated under normal conditions. normal condition is defined as below; - temperature : 20 15 - humidity : 65 20% - display pattern : continually changing pattern (no t stationary) (b) if the product will be used in extreme conditio ns such as high temperature, humidity, display patterns or operation time etc.., it is strongly recommended to contact sec for application engineering advice. otherwise, its reliability and function may not be guaranteed. extreme conditions are commonly found at airports, transit stations, banks, stock market, an d controlling systems. www..net www..net

(b) avoid condensation of water. it may result in i mproper operation or disconnection of electrode. (c) do not exceed the absolute maximum rating value . ( supply voltage variation, input voltage variation, variation in part contents and environmental temperature, and so on) otherwise the module may be damaged. (d) if the module keeps displaying the same pattern for a long period of time, the image may be "sticked" to the screen. to avoid image sticking, it is recommended to use a screen saver. (e) this module has its circuitry pcb's on the rear side and should be handled carefully in order not to be stressed. (f) please contact sec in advance when you display the same pattern for a long time. www..net www..net
