13. GENERAL PRECAUTION13-1 Use RestrictionThis product is not authorized for use in life supporting systems, aircraftnavigation control systems, military systems and any other application whereperformance failure could be life-threatening or otherwise catastrophic.13-2 Disassembling or ModificationDo not disassemble or modify the module. It may damage sensitive parts insideLCD module, and may cause scratches or dust on the display. Ampire does notwarrant the module, if customers disassemble or modify the module.13-3 Breakage of LCD Panel(1) If LCD panel is broken and liquid crystal spills out, do not ingest or inhaleliquid crystal, and do not contact liquid crystal with skin.(2) If liquid crystal contacts mouth or eyes, rinse out with water immediately.(3) If liquid crystal contacts skin or cloths, wash it off immediately with alcoholand rinse thoroughly with water.(4) Handle carefully with chips of glass that may cause injury, when the glass isbroken.13-4 Electric Shock(1) Disconnect power supply before handling LCD module.(2) Do not pull or fold the LED cable.(3) Do not touch the parts inside LCD modules and the fluorescent LED’sconnector or cables in order to prevent electric shock.13-5 Absolute Maximum Ratings and Power Protection Circuit(1) Do not exceed the absolute maximum rating values, such as the supplyvoltage variation, input voltage variation, variation in parts’ parameters,environmental temperature, etc., otherwise LCD module may be damaged.(2) Please do not leave LCD module in the environment of high humidity andhigh temperature for a long time.(3) It’s recommended to employ protection circuit for power supply.Date : 2012/04/24 30

13-6 Operation(1) Do not touch, push or rub the polarizer with anything harder than HB pencillead.(2) Use fingerstalls of soft gloves in order to keep clean display quality, whenpersons handle the LCD module for incoming inspection or assembly.(3) When the surface is dusty, please wipe gently with absorbent cotton orother soft material.(4) Wipe off saliva or water drops as soon as possible. If saliva or water dropscontact with polarizer for a long time, they may causes deformation or colorfading.(5) When cleaning the adhesives, please use absorbent cotton wetted with alittle petroleum benzine or other adequate solvent.13-7 MechanismPlease mount LCD module by using mounting holes arranged in four cornerstightly.13-8 Static Electricity(1) Protection film must remove very slowly from the surface of LCD module toprevent from electrostatic occurrence.(2) Because LCD module use CMOS-IC on circuit board and TFT-LCD panel, itis very weak to electrostatic discharge. Please be careful with electrostaticdischarge. Persons who handle the module should be grounded throughadequate methods.13-9 Strong Light ExposureThe module shall not be exposed under strong light such as direct sunlight.Otherwise, display characteristics may be changed.13-10 DisposalWhen disposing LCD module, obey the local environmental regulations.13-11 OthersAMIPRE will provide one year warrantee for all products and three monthswarrantee for all repairing products.Date : 2012/04/24 31
