6. Maintaining the Waterproof Function
Remove the O-ring.
Open the Case and remove the O-ring.
Procedure
ᕃInsert the O-ring remover into the gap between the O-ring and O-ring groove wall.
ᕄBring the tip of the inserted O-ring remover below the O-ring. (Be careful not to damage
the groove with the tip of the O-ring remover.)
ᕅLift the O-ring, pinch its with your fingertips and pull it out of the Case.
Remove any sand, dirt, etc.
After visually checking that dirt has been removed from the O-ring, checking for attached
sand and other foreign matter, as well as for damage and cracks can be done by squeezing
the entire circumference of the O-ring lightly with your fingertips.
Remove attached foreign matter from the O-ring groove with a clean cloth or a cotton swab.
Also remove any sand or dirt attached to the any part of the Case that comes into contact
with the O-ring.
:•When a mechanical pencil or a similar other 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 fingertips, 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.
