Storage:
In addition to the above environmental considerations, the
F20 should be stored in an environment that is dry,
corrosive-free, and not in direct sunlight.
Correct storage:
Prevents premature component failures caused by
environmental factors such as moisture or corrosive gases.
Exposure to high humidity or corrosive environments will
prematurely degrade the electronic components in any
electronic device regardless of its use or manufacturer.
