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.

9-5. 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.
