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.
Making sure the case is waterproof
Check the parts that ensure the case is waterproof.
1. Make sure that the O-ring between the front and rear lids of the
case is attached firmly and the buckle is tightly secured.
2. Make sure that the O-rings between the case and standard port are
attached firmly and that the buckles are tightly secured.
3. Make sure that the O-ring on the TTL cable connector cap is
attached firmly and that the cap is fitted tightly to the connector.
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.
ț Damage to the O-ring groove or the O-ring contact surface.
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 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).
