(10/10) 2006-04-28 (ver.0.1) LTD121EXVV for safety lcd module is generally designed with precise parts to achieve light weighted thin mechanical dimensions. in using our modules, make certain that you fully understand and put into practice the warnings and safety precautions detailed in engineering informat ion no.ee-d-001a,"cautions and instructions for toshiba matsushita display technology co., ltd lcd modules". refer to individual specifications and technical data s heets (hereinafter called "td") for more detailed technical information. 1) special purposes a) toshiba matsushita display technology's standard lcd modules have not been customized for operation in extreme environments or for use in applications where performance fa ilures could be life-threatening or otherwise catastrophic. b) since toshiba matsushita display technology's standar d lcd modules have not been desi gned for operation in extreme environments, they must never be used in devices that will be exposed to abnormally high levels of vibration or shock which exceed toshiba matsushita display tec hnology's published specification limits. c) in addition, since toshiba matsushita display tec hnology standard lcd modules have not been designed for use in applications where performance failures could be life-threatening or catastrophic, they must never be installed in aircraft navigation control systems (such as, but not limited to traffic collision avoidance system and air traffic indicator), in milit ary defense or weapons systems, in critical indu strial process-control systems (e.g., t hose involved in the production of nuclear energy), or in critical medical devi ce or patient life-support systems. 2) disassembling or modification do not disassemble or modify the module. it may damage sensitive pa rts inside lcd module, and may cause scratches or dust on the display. toshiba matsushita display technology doses not warrant the module, if customer di sassembled or modified it. 3) breakage of lcd panel do not ingest liquid crystal material, do not inhale this material, and do not contact the material with skin, if lcd panel is broken and liquid crystal material spills out. if liquid crystal material comes into mouth or eyes, rinse mouth or eyes out with water immediately. if this material contact with skin or cl oths, wash it off immediately with al cohol and rinse thoroughly with water. 4) glass of lcd panel be careful with chips of glass that may cause in juring fingers or skin, when the glass is broken. 5) electric shock disconnect power supply before handling lcd module. do not touch the parts inside lcd module and the fluorescent la mp's connector or cables in order to prevent electric shock, because high voltage is supplied to these parts from the inverter unit while power supply is turned on. 6) absolute maximum ratings and power protection circuit do not exceed the absolute maximum rating values under the worst probable conditions caused by the supply voltage variation, input voltage variation, variation in parts' constants, environmental temperature, etc., otherwise lcd module may be damaged. employ protection circuit for power supply, whe never the specification or td specifies it. suitable protection circuit should be applied for each system design. 7) disposal when dispose lcd module, obey to the applicable environmental regulations. ! www.jxlcd.com www.jxlcd.com
