Replace consumable products.
The O-ring is a consumable product. Independent of the number of
times the Case is used, it is recommended that the O-ring should
be replaced by a new one at least once a year.
Deterioration of the O-ring is accelerated by the use conditions and
the storage conditions. Replace the O-ring even before a year has
passed if it shows signs of damage, cracking or loss of elasticity.
Note: • Please use original Olympus products for the silicone O-ring
grease, the silica gel, and the O-ring. These consumable
products also can be purchased at an Olympus service station.
