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.
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.
Damage to the O-ring groove or the O-ring contact surface.
When closing the Case, check for catching of the hand strap and
silica gel 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 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).
