HANDLING THE LCD MODULE

Safety Precautions

In the event that the screen is damaged or the liq-
uid crystal (fluid) leaks, do not breathe in or drink 
this fluid. Also, never touch this fluid.
Such actions could cause toxicity or skin irritation. 
If this fluid should enter the mouth, rinse the mouth 
thoroughly with water. If the fluid should contact the 
skin or clothing, wipe off with alcohol, etc., and 
rinse thoroughly with water. If the fluid should enter 
the eyes, immediately rinse the eyes thoroughly 
with running water.

Precautions for Handling the LCD 
Module

The LCD module can easily be damaged during 
disassembly or reassembly; therefore, always 
observe the following precautions when handling 
the module.

1. When attaching the LCD 

module to the LCD cover, 
position it appropriately 
and fasten at the position 
where the display can be 
viewed most conve-
niently.

2. Carefully align the holes at all four corners of the LCD 

module with the corresponding holes in the LCD cover 
and fasten with screws. Do not strongly push on the 
module because any impact can adversely affect the 
performance. Also use caution when handling the 
polarized screen because it can easily be damaged.

3. If the panel surface becomes 

soiled, wipe with cotton or a 
soft cloth. If this does not 
remove the soiling, breathe 
on the surface and then wipe 
again. If the panel surface is 
extremely soiled, use a CRT 
cleaner as a cleaner. Wipe off the panel surface by 
drop the cleaner on the cloth. Do not drop the cleaner 
on the panel. Pay attention not to scratch the panel sur-
face. 

4. Leaving water or other fluids on 

the panel screen for an extended 
period of time can result in discol-
oration or stripes. Immediately 
remove any type of fluid from the 
screen. 

5. Glass is used in the panel, so do not 

drop or strike with hard objects. 
Such actions can damage the panel. 

6. CMOS-LSI circuitry is used in the 

LCD module, so avoid damage due 
to static electricity. When handling 
the module, use a wrist ground or 
anchor ground.

7. Do not expose the LCD 

module to direct sun-
light or strong ultravio-
let rays for an extended 
period of time. 

8. Do not store the LCD 

module below the tem-
perature conditions described in the specifications. 
Failure to do so could result in freezing of the liquid 
crystal due to cold air or loss of resilience or other 
damage. 

9. Do not disassemble the 

LCD module. Such 
actions could result in 
improper operation. 

10.When transporting the 

LCD module, do not use 
packing containing 
epoxy resin (amine) or silicon resin (alcohol or oxim). 
The gas generated by these materials can cause loss of 
polarity. 

CAUTION

The metal edges of the LCD 
module are sharp, so use cau-
tion to avoid injury.
