Heat-resistant: When there is no current and the temperature is +70℃,It is normal for 72 hour. Cold-resistant: When the electric line is cut off and the temperature is -20℃,We put it For 72 hour in the room. When we test it, It is normal. Falling test: You may lay it from the place above the ground about 200cm and let it fall itself on the broad of the ground, Then you can find it still may work an usual.
