Olympus PT-038 - Underwater Housing For FE-230 Instruction Manual page 75

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.
5 Deterioration of the O-ring is accelerated by the use conditions and
the storage conditions. Replace the O-ring immediately with a new
one if it shows signs of damage, crack or loss of elasticity.

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.
