5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks. 6. CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle grounding device when handling the module. Satellite L450/L450D Series Maintenance Manua[...]

7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods. 8. Do not store the module at temperatures below its specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9. Do not disassemble the LCD module. Disassem bly can cause malfunctions. A-4 [CONFIDENTIAL][...]

10. If you transport the module, do not use packing material that contains epoxy resin (am ine) or silicon glue (alcohol or oxime). These materials can release gas that can dam age the panel’s polarization. Satellite L450/L450D Series Maintenance Manual [CONFIDENTIAL] A-5[...]
