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.

 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.

 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 the advance test should show water leakage with

normal handling, stop using the Case and contact your

dealer or an Olympus service station (listed on the rear

page of this instruction manual).
