Final Test
After the electronic flash has been inserted in the case, you should perform the final system check.
This covers all tests that you must carry out to make sure that no water can enter the case. The tests
are easy to do and only take about 5 minutes. All you need is a bowl or tub of water.
※The following procedure was originally developed to test for water penetration inside the
camera case. The test procedure for the waterproof flash case is identical, so please
follow these steps.

Explanatory image
As the Case is transparent, waterdrops
entering into it can be confirmed easily.
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.
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?
Check carefully for air bubbles!
Do not perform any operation yet,
but just observe.
Remove the Case from the water and
check that no water has accumulated at
the bottom of the Case.
Perform very careful confirmation.
Check carefully for air bubbles!
Try operation of the buttons used frequently.
Check carefully for air bubbles!
If there is still no entry of water, everything is
OK!
This is very important!
Has the silica gel become moist?
Please check carefully!
As the inside can be seen, the inspection for
entry of water also can be made securely!
Now everything is all right!
Have a nice dive!
