CAUTION
: • When a mechanical pencil or a similar other sharp
object is used to remove the O-ring or to clean the
inside of the O-ring groove, the Case and the O-ring
may be damaged and water leakage may be caused.
• When the O-ring is checked with the fingertips, take
care not to stretch the O-ring.
• Never use alcohol, thinner, benzene or similar solvents
or chemicals detergents to clean the O-ring. When such
chemicals are used, it is likely that the O-ring will be
damaged or that its deterioration will be accelerated.
Install the O-ring.
Confirm that no foreign matter is attached, apply a thin coat of the
accessory grease to the O-ring, and fit the O-ring into the groove. At
this time, confirm that the O-ring does not stick out from the groove.
How to Apply Grease to the O-ring
Apply the
exclusive
1
lubricant to each
O-ring.
Spread the
2
lubricant all over
the O-ring.
Check that the
O-ring is free of
3
scratch or
unevenness.
Apply lubricant on
4
the O-ring contact
surface.
Make sure that your fingers and the O-
ring are free of dirt, and squeeze about
5 mm of lubricant onto a finger. (5 mm
is the most appropriate amount.)
Surround the lubricant with three
fingers and spread it over the ring. Be
careful not to use excessive force as
this may stretch the O-ring.
After spreading the lubricant, check
visually and by touch that the O-ring is not
scratched and that its surface is flat. If it is
damaged in any way, replace it with a
brand-new O-ring.
Use the lubricant remaining on the
fingers to clean and lubricate the
case's contact surface.

CAUTION
:
• Always perform maintenance of the waterproof
function even when the Case has been opened to
exchange the battery or the image storage during
shooting. Neglecting this maintenance may become
the cause of water leakage.
• When the Case is not to be used for a long time,
remove the O-ring from the groove to prevent
deformation of the O-ring, apply a thin coat of silicone
grease, and store it in a clean plastic bag or the like.
• When drying is done with salt attached, it is likely that
a function impairment will be caused. After use,
always wash off any salt.
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.
