: • 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
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.
CAUTION
Use a clean cloth not easily shedding fibers, or cotton swab, tissue
paper or the like, to remove any foreign matter from the O-ring groove.
Clean the O-ring contact surface on the front lid in the same way to
remove any sand and dirt.
