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 duri ng assembly or disassembly. Observe the following precautions when handling the LCD module: 1. When installing the LCD module in the LCD cove r, be sure to seat it so that it[...]

Appendices Appendix. A Handling the LCD Module 3. If the panel’s surface gets dirty, wipe it with co tton or a soft cloth. If it is still dirty, try breathing on the surface to create a light cond ensate and wipe it again. If the surface is very dirty, we recomme nd a CRT cleaning agent. Apply the agent to a cloth and then wipe the panel’s surf[...]

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 m odule, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the module. Satelli[...]

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. Do not disassemble the LCD module. Disassembly [...]

Appendix. A Handling the LCD Module Appendices 10. If you transport the module, do not use pack ing material that c ontains epoxy resin (amine) or silicon glue (alcohol or oxime). These m aterials can release gas that can damage the panel’s polarization. Satellite A50S/TECRA A3X Maintenan ce Man ual (960-534) [CONFIDENTIAL ] A-5[...]
