Q7:	How can I check for water leakage?
A7:	For confirmation, perform the advance test and the final test after
	loading the camera. The advance test with immersing the Case
	without the camera to the intended use depth to check for water
	leakage is the most accurate test, but when this is difficult, it is safer
	to perform this test even at a depth of 1 m or in a bathtub. The final
	test also can be performed in a bathtub or a bucket.

7Throwing 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.

1Never 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.

2Use 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.
