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.

chemical detergents to clean the O-ring. When such
chemicals are used, it is to be feared that the O-ring will
be damaged or that its deterioration will be accelerated.

free clean cloth or cotton swab. Also remove any sand or dirt attached
to the O-ring contact surface on the front lid of the case.
