2. Advance Check of the Case

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 using, always perform the following advance checks.

1 Before installing the digital camera in the Case, immerse the empty 

Case to confirm that there is no water leakage. 
We recommend to immerse the empty Case to the intended water 
depth, however, if you cannot perform this way, check the Case by 
referring “Water Leakage Test” (P.19).

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:

If a leak is detected in normal handling, do not use the Case and contact 
Olympus.
