  • Page 151 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 152 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 153 Handling the LCD Module 9. Do not disassemble the LCD module. Disassembly can cause malfunctions. 10.
