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
1
Apply the exclusive
lubricant to each O-
ring.
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.)
2
Spread the
lubricant all over
the O-ring.
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.
3
Check that the
O-ring is free of
scratch or
unevenness.
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.
4
Apply lubricant on
the O-ring contact
surface.
Use the lubricant remaining on the
fingers to clean and lubricate the case's
contact surface.
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.
:•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.
CAUTION
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.
