Be sure to rinse the watch in fresh water, and wash out all
seawater, soil, sand, etc.

After cleaning the watch in fresh water, be sure to wipe it
thoroughly dry.

If the watch is left soaked in water for a long time for removing
salt or other purposes, the auto sensor function is activated
and consumes battery energy.

If a grain of sand or the like gets in the pressure sensor, rinse
the watch in fresh water to wash it out.  Do not use anything
with a pointed tip to pick it out or an air blast to blow it out.  If
it sticks in the pressure sensor and cannot be washed out,
consult the retailer from whom it was purchased.

Be careful not to expose the pressure sensor to solvents such
as alcohol and gasoline, as this will cause malfunctions.

When the surface interval time is less than 10 minutes, time/
calendar setting, FO

 setting and hour correction cannot be

made.

If the measurement exceeds the measurable range of the
watch, all the segments of the display flash.  In that case, the
watch cannot be used for diving for 48 hours after the dive is
over.
