CAUTION
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.
Do not place the housing on desks or other tabletop surfaces with the
rear case opened and the inner side facing down. Be careful as doing so
may cause the projection on the rear case to become deformed or
damaged. (Fig. 3)
When opening the rear case after use in the water, open it carefully not to
let water or sand enter inside the housing.
