7. Examination results document
Since a performance is guaranteed, an examination results document does not submit.
8. Storage conditions
8.1. It is not dropping a 2nd-packing box or not pushing and crushing in the case of storage.
8.2. Direct rays are avoided and they are room temperature and humidity (dehumidification environment is
desirable if it can do).
8.3. A storage term should give half a year as a standard (even if it passes a storage term, there is no rapid
degradation).
