    Appendix. A Handling the LCD Module Appendices Appendix. A Appendix A Handling the LCD Module Precautions for handling the LCD module The LCD module can be easily damaged during assembly or disassembly. Observe the following precautions when handling the LCD module: 1.
  • Page 346 Appendices Appendix. A Handling the LCD Module 3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again. If the surface is very dirty, we recommend a CRT cleaning agent.
  • Page 347 Appendix. A Handling the LCD Module Appendices 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.
  • Page 348 Appendices Appendix. A Handling the LCD Module 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 specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9.
  • Page 349 Appendix. A Handling the LCD Module Appendices 10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxime). These materials can release gas that can damage the panel’s polarization. Satellite A50S/TECRA A3X Maintenance Manual (960-534) [CONFIDENTIAL]...
