7.2 CAUTIONS
∗
Do not shock and press the LCD panel and the backlight! There is a danger of
breaking, because they are made of glass. (Shock: Equal to or no greater than 539m/s
2
and equal to or no greater than 11ms, Pressure: Equal to or no greater than 19.6 N
(
φ
16mm jig))

7.3 ATTENTIONS
!
7.3.1 Handling of the product
①
Take hold of both ends without touching the circuit board when the product (LCD module) is
picked up from inner packing box to avoid broken down or misadjustment, because of stress to
mounting parts on the circuit board.
②
When the product is put on the table temporarily, display surface must be placed downward.
③
When handling the product, take the measures of electrostatic discharge with such as earth band,
ionic shower and so on, because the product may be damaged by electrostatic.
④
The torque for product mounting screws must never exceed 0.23N
⋅
m. Higher torque might result
in distortion of the bezel.
And the length of product mounting screws must be
≤
2.0mm.
⑤
The product must be installed using mounting holes without undue stress such as bends or twist
(See outline drawings). And do not add undue stress to any portion (such as bezel flat area). Bends
or twist described above and undue stress to any portion may cause display mura.
⑥
Do not press or rub on the sensitive product surface. When cleaning the product surface, wipe it
with a soft dry cloth.
⑦
Do not push or pull the interface connectors while the product is working.
⑧
When handling the product, use of an original protection sheet on the product surface (polarizer) is
recommended for protection of product surface. Adhesive type protection sheet may change color
or characteristics of the polarizer.
⑨
Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of
thin layer and the construction of LCD panel. But, if you contact with liquid crystal by any chance,
please wash it away with soap and water.
