Remove any sand, dirt, etc.
After visually checking that dirt has been removed from the O-ring, checks
for sand and other foreign matter adhered, damage and cracks can be
done by squeezing the entire circumference of the O-ring lightly with your
fingertips.
Remove any foreign matter adhered to the O-ring groove using a lint-free
clean cloth or cotton swab. Also remove any sand or dirt adhered to the
O-ring contact surface on the front lid of the Case.
CAUTION:
• 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 occur.
• Take care not to stretch the O-ring.
• Never use alcohol, thinner, benzene or similar solvents or chemical
detergents to clean the O-ring. When such chemicals are used, the O-ring
may be damaged or its deterioration will be accelerated.
