Q9 : What are the important points for O-ring maintenance?

A9 : Please observe 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,

it is to be feared that the O-ring will be damaged or that its deterioration

will be accelerated.

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

attached to Cases up to PT-008 (red cap) and the grease of other

companies are not suitable for this silicone O-ring, and 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. However, it may facilitate attachment of

sand, dirt, etc.

A thin, uniform coat produces the best result.

(4) The O-ring is a consumable product. Replace it at least once a year.

(5) Deterioration of the O-ring is accelerated by the use conditions and the

storage conditions. Replace the O-ring immediately by a new one if it

shows signs of damage, cracking or loss of elasticity.

Q10: What are the important points for Case maintenance?

A10: Please observe the following items.

(1) Never use the following chemicals for cleaning, corrosion protection,

defogging, repair or other purposes.

• Never use alcohol, thinner, benzene or similar volatile organic solvents

or chemical detergents to clean the Case. Pure water or lukewarm water

is sufficient for cleaning.

• Do not use anticorrosion agents on the metal parts. The metal parts are

made of aluminum, brass or stainless steel. Cleaning with pure water is

sufficient.

• Do not use commercial defogging agents. Always use the original

Olympus defogging silica gel.

• Do not use adhesive for repairs or other purposes. When repair is

required, please contact a service station of OLYMPUS CORPORATION

or your dealer.
