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. When installing the LCD module in the LCD c over, be sure to seat it so that it is 
properly aligned and maximum visibility of the display is maintained. 
 
 
2.  Be careful to align the four holes at the  right side and left side of the LCD module 
with the corresponding holes in the LCD cove r before securing the module with four 
screws. Do not force the module into place,  because stress can affect its performance. 
Also, the panel’s polarized surface is easily scarred, so be carefull\
y when handling it.

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 ag\
ain. 
  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. Do  not apply cleanser directly to the panel. 
Also, never scratch the surface. 
 
4.  If water or other liquid is left on the pa nel’s surface for a long period, it can change 
the screen’s tint or stain it.  Be sure to quickly wipe off any liqui\
d.

5. Glass is used in the panel, so be careful not to drop it or let it strik\
e 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. 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. 
 
8. Do not store the module at temperatures  below specifications. Cold can cause the 
liquid crystals to freeze, lose their elasticity or otherwise suffer dam\
age.

9. Do not disassemble the LCD module. Disassembly can cause malfunctions. 
 
 
10. If you transport the module, do not use pack ing material that contains epoxy resin 
(amine) or silicon glue (alcohol or oxide).  These materials can release gas that can 
damage the panel’s polarization.
