Remove any sand, dirt, etc.

After visually checking that dirt has been removed from the O-ring, check

for attached sand and other foreign matter, as well as for damage and

cracks by squeezing the entire circumference of the O-ring lightly with

your ﬁ ngertips.

Remove attached foreign matter from the O-ring groove with a lint-free

clean cloth or a cotton swab. Also remove any sand or dirt attached to any

part of the Case that comes into contact with the O-ring.

• When a 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 ﬁ ngertips, 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.

Apply the exclusive

lubricant to the

O-ring

Spread the lubricant

all over the O-ring.

Check that the O-ring

is free of scratches

or unevenness.

• 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 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.

Make sure that your ﬁ ngers and the Oring

are free of dirt, then squeeze the appropriate

amount of exclusive lubricant onto a ﬁ nger to

spread onto the entire circumference of the

O-ring (approx. 15 mm is adequate).

Apply the lubricant with 3 ﬁ ngers and spread

it over the O-ring. Be careful not to use force

as this may stretch the Oring.

After spreading the lubricant, check visually

and by touch that the O-ring is not scratched

and that its surface is ﬂ at. If it is damaged in

any way, be sure to replace it with a brand-

new O-ring.
