1
Place the Case
slowly into the water.
As the Case is transparent,
waterdrops entering into it can be
confirmed easily.

Case for only three
seconds.
In case of trouble with the O-ring,
three seconds are enough for water
to enter. Are there air bubbles
coming out between the lids?
Please check carefully.

Check that no water
has entered into the
Case.
Remove the Case from the water and
check that no water has accumulated at
the bottom of the Case.
Is there any water trickling down?

Next, immerse the
Case for 30
seconds.
Check carefully for air bubbles!
Do not perform any operation yet,
but just observe.
