CAUTION
Opening and Closing the Housing
Opening the lock knob
Before opening the rear case, make
sure that the housing is completely
dry and free of salt deposits. If you
find any salt deposits, rinse with fresh
water and wipe off water completely
with a soft cloth.
Never turn the knob without pulling
the tab, as it may result in damage
to the knob.
The lock knob only turns up to 90
degrees. The lock knob may become
damaged if it is turned forcibly.
When pulling the tab outward, be sure to use the tips of your fingers, not
your fingernails.
Never use the tab/lock knob underwater.
When opening the rear case after use in the water, open it carefully not to
