1
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
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.
: • 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.
