Appendix A Handling the LCD Module Precautions for Handling the T1960CS/T1960CT LCD Module The computer's LCD module can be easily damaged during assembly or disassembly. Therefore, please observe the following precautions when handling the LCD module. When installing the LCD module in the LCD cover, be sure to seat it so that it is properly aligned and maximum visibility of the display is maintained.
Page 150 Be sure to quickly wipe off any liquid. 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. T1960CS/T1960CT...
Page 151 Do not expose the module to direct sunlight or strong ultraviolet rays for long periods. Do not store the module at temperatures below specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. T1960CS/T1960CT...
Page 152 Do not disassemble the LCD module. Disassembly can cause malfunctions. 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 panels’ polarization. T1960CS/T1960CT...
