Don't give excessive external shock, or drop from a high place. 2. If the LCD screen is damaged and the liquid crystal leaks out, do not lick and swallow. When the liquid is attach to your hand, skin, cloth etc, wash it off by using soap and water thoroughly and immediately. 3. Don't apply excessive force on the surface of the LCM. 4. If the surface is contaminated ,clean it with soft cloth. If the LCM is severely contaminated , use Isopropyl alcohol/Ethyl alcohol to clean. Other solvents may damage the polarizer . The following solvents is especially prohibited: water , ketone Aromatic solvents etc. 5. Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a high-humidity environment. 6. Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable. 7. Don’t disassemble the LCM. 8. To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment. - Be sure to ground the body when handling the LCD modules. - - Tools required for assembling, such as soldering irons, must be properly grounded. - - To reduce the amount of static electricity generated, do not conduct assembling and other work under dry conditions. - - The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this protective film since static electricity may be generated. - 9. Do not alter, modify or change the the shape of the tab on the metal frame. 10. Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. **FS-KTBCD430-D1 10/Oct/2011 PAGE 13 OF 15** 11. Do not damage or modify the pattern writing on the printed circuit board. 12. Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector 13. Except for soldering the interface, do not make any alterations or modifications with a soldering iron. 14. Do not drop, bend or twist LCM. ## **10.2 Storage** 1. Store in an ambient temperature of 5 to 45 ° C, and in a relative humidity of 40% to 60%. Don't expose to sunlight or fluorescent light. 2. Storage in a clean environment, free from dust, active gas, and solvent. 3. Store in antistatic container. ## **11.
