Observe the following precautions when handling the LCD module: 1. 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 108 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. Apply the agent to a cloth and then wipe the panel’s surface.
  • Page 109 Handling the LCD Module 6. CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the module. 7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods.
  • Page 110 Handling the LCD Module 9. Do not disassemble the LCD module. Disassembly can cause malfunctions. 10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxide). These materials can release gas that can damage the panel’s polarization. Maintenance Manual (960-949)
