Remove the O-ring, wipe off any salt, sand, dust, etc., and also clean the
O-ring groove and the O-ring contact surface in the same way and then
dry them. When an object with a sharp tip is used to remove the O-ring
from the groove, the O-ring may be damaged and water leakage may be
caused. Always use the provided O-ring remover.
Q6 : How should I take pictures under water?
A6 : Please observe the following items for shooting under water.
(1) Fix the Case with the accessory hand strap to your wrist.
(2) When you place a finger onto the lens window, the finger will appear in
the photo. Pay attention to the position of your fingers when holding the
Case.
(3) When pressing the shutter lever, hold the Case securely with both hands
and operate the lever quietly to prevent camera shake.
(4) Before shooting, look through the LCD monitor window on the rear of the
Case to confirm that a picture is displayed on the camera's LCD monitor.
In order to avoid missing shutter chances due to an exhausted battery,
you should always replace the battery with a fully charged battery before
each dive.
Q7 : How can I check for water leakage?
A7 : For confirmation, perform the advance test and the final test after loading
the camera. The advance test with immersing the Case without the
camera to the intended use depth to check for water leakage is the most
accurate test, but when this is difficult, it is safer to perform this test even
at a depth of 1 m or in a bathtub. The final test also can be performed in
a bathtub or a bucket.
Q8 : What are the causes for entry of water?
A8 : The main causes for the entry of water are shown below. Please check
them most carefully.
(1) Forgetting to install the O-ring
(2) The O-ring is partly or completely outside the groove.
(3) Damage, deterioration, or deformation of the O-ring
(4) Sand, fibers, hair or other foreign matter on the O-ring
(5) When foreign matter (sand, fiber, hair, etc.) is stuck to the O-ring
grooves or O-ring contact surfaces.
(6) Catching of the strap, the bag of silica gel, etc. at the time of sealing the Case.
(7) Throwing the Case from a boat into the water, jumping with the Case into
the water, or other sudden application of strong forces onto the Case.
When entering the water, hand the Case over quietly or avoid impacts in
other ways.
