Install the O-ring.
Confirm that no foreign matter is adhered, apply a thin coat of the grease
provided to the O-ring, and fit the O-ring into the groove. At this point,
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 lubricant
2
all over the O-ring.
Check that the O-ring
3
is free of scratches or
unevenness.
Apply lubricant on the
4
O-ring 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 cause 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.
• Drying the Case with salt adhered may impair the function. Always wash
off any salt after use.
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.)
Apply the lubricant with three fingers and
spread it over the ring. Be careful not to
use 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, be sure to
replace it with a brand-new O-ring.
Use the lubricant remaining on the
fingers to clean and lubricate the case's
contact surface.
