5.2 Storage Condition
The products should be stored in the room ,where the temperature/humidity is stable. And avoid 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.
5.3 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.
