(8) A screw which is fastened up the steels should be a machine screw. (if not,
it causes metallic foreign material and deal LCM a fatal blow)

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to
electrostatic discharge. Make certain that treatment persons are connected to
ground through wrist band etc. And don’t touch interface pin directly.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
When storing modules as spares for a long time, the following precautions are
necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or
fluorescent light. Keep the temperature between 5°C and 35°C at normal
humidity.
(2) The polarizer surface should not come in contact with any other object. It is
recommended that they be stored in the container in which they were
shipped.
9-6. Handling Precautions for Protection Film
(1) The protection film is attached to the bezel with a small masking tape.
When the protection film is peeled off, static electricity is generated
between the film and polarizer. This should be peeled off slowly and
carefully by people who are electrically grounded and with well ion- blown
equipment or in such a condition, etc.
(2) When the module with protection film attached is stored for a long time,
sometimes there remains a very small amount of glue still on the bezel after
the protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on the bezel
surface or its vestige is recognized, please wipe them off with absorbent
cotton waste or other soft material like chamois soaked with normal-
hexane.
