2. Advance Check of the Case
Advance test before use
This Case has been the subject of thorough quality control for the
parts during the manufacturing process and thorough function
inspections during the assembly. In addition, a water pressure test
is performed with a water pressure tester for all products to confirm
that the performance conforms to the specifications. However,
depending on the carrying and storage conditions, the maintenance
status, etc., the waterproof function may be damaged.
Before diving, always perform the following advance test and the
water leakage test after installation of the camera.
Advance Test
1. Before installing the digital camera in the Case, immerse the
empty Case to the intended water depth to confirm that there is
no water leakage.
2. Main causes of water leakage are as follows.
ț The O-ring has not been installed.
ț A part of the O-ring or the entire O-ring is outside the specified
groove.
ț O-ring damage, cracks, deterioration or deformation
ț Sand, fibers, hair or other foreign matter sticking to the O-ring,
the O-ring groove or the O-ring contact surface on the front lid
ț Damage to the O-ring groove or the O-ring contact surface on
the front lid
ț When closing the Case, check for catching of the hand strap and
silica gel after the above causes have been eliminated.
: • The most suitable method for checking water leakage is
to immerse the Case to the intended water depth. When
this is difficult, water leakage also can be checked at a
shallow depth with no water pressure. Do not feel that
this is troublesome, but perform this test.
• If a leak is detected in normal handling during testing,
do not use the Case and contact Olympus.
