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 flash.
Advance Test
1. Before inserting the electronic flash, take the empty case to the intended depth and
make sure that no water gets inside the case.
2. Main causes of water leakage are as follows.
・
One or more O-rings have not been installed.
・
Part of an O-ring or an 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.
・
Damage to an O-ring groove or O-ring contact surface.
・
When all of the above causes have been eliminated, check the hand strap and
silica gel when closing the Case.
：
• 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).
