G

F

such places where there are large temperature changes. Please store the products at the foll­owing conditions:
Temperature: -10 to + 40 C Humidity: 15 to 85% R.H.

2.2 Expire Date on Storage
Expire date (Shelf life) of the products is six months after deliveried under the conditions of a
sealed and an unopened package. Please use the products within six months after deliveried.
If you store the products for a long time (more than six months), use carefully because the
