How to Apply Grease to the O-ring
Apply the exclusive
1
lubricant to the
O-ring.
Spread the
2
lubricant all over
the O-ring.
Check that the
O-ring is free of
3
scratches or
unevenness.
CAUTION:
• Always perform maintenance of the waterproof function even when the
Case has been opened every shooting. Neglecting this maintenance may
cause water leakage.
• When the Lens Port 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.
Examples of foreign matter sticking to the O-ring

Make sure that your fingers and the
O-ring are free of dirt, then
squeeze the appropriate amount of
exclusive lubricant onto a finger to
spread onto the entire
circumference of the O-ring
(approx. 15 mm is adequate).
Apply the lubricant with 3 fingers
and spread it over the O-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.
