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 final 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.
• The O-ring has not been installed.
• A part of the O-ring or the entire O-ring is outside the specified
groove.
• O-ring damage, cracks, deterioration or deformation
• 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
• Damage to the O-ring groove or the O-ring contact surface on the
front lid
• Catching of the strap, silica gel, etc. when closing the Case
Perform the test after the above causes have been eliminated.
CAUTION:
• 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.
