Q8:

What are the causes for entry of water?

A8:

The main causes for the entry of water are shown below. Please

check with special care.

1 The O-ring has not been installed.

2 The O-ring is partly or completely outside the groove.

3 Damage, deterioration or deformation of the O-ring

4 Sand, fibers, hair or other foreign matter on the O-ring

5 Sand, fibers, hair or other foreign matter sticking to the O-ring

grooves or the O-ring contact surfaces

6 Catching of the strap, the bag of silica gel, etc. when sealing the

Case

7 Throwing the Case from a boat into the water, jumping with the

Case into the water, or other sudden application of strong forces

onto the Case. When entering the water, hand the Case over

gently or avoid impacts in other ways.

Q9:

What are the important points for O-ring maintenance?

A9:

Pay special attention to the following items.

1 Never use alcohol, thinner, benzene or similar organic solvents

or chemical detergents to clean the O-ring. When such

chemicals are used, the O-ring may be damaged or its

deterioration will be accelerated.

2 Use the genuine Olympus silicone O-ring grease (white cap).

The grease (red cap) used for previous Cases up till PT-008 and

the grease from other companies are not suitable for this silicone

O-ring. The use of such grease may cause deterioration of the

surface and impairment of the waterproof function.

3 In order to avoid deformation of the O-ring when the Case is not

used for a long time, remove the O-ring from the Case, apply a

thin coat of the special grease, and store the O-ring in a clean

plastic bag. For reuse, confirm that the O-ring is free of damage

and cracks, that it has sufficient elasticity, that the surface is free

of stickiness and other abnormalities, and use it after applying a

thin coat of the special grease. Excessive application of grease

does not improve the waterproof function or the permissible

withstand pressure. It will cause sand and dust to adhere more

easily. A thin, uniform coat produces the best result.

4 The O-ring is a consumable part. Replace it at least once a year.
