HANDLING THE LCD MODULE Safety Precautions In the event that the screen is damaged or the liquid 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 conveniently. 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. 4. Leaving water or other fluids on the panel screen for an extended period of time can result in discoloration 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 sunlight or strong ultraviolet rays for an extended period of time. 8. Do not store the LCD module below the temperature 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. CAUTION The metal edges of the LCD module are sharp, so use caution to avoid injury. 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 surface. 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. 5

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.
