Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to read this manual carefully and keep it on hand for later reference
when necessary.

Important!

The fishing/hunting level indicator and moon phase indicator produced by this watch
are all based on calculations that use the watch’s current time, date, and Home Site
settings. Because of this, you should make sure that the current date and time, and
your Home Site data are all correct before using the indicators.

• When fishing or hunting, always take proper precautions to ensure your own
personal safety and the personal safety of others around you.

• Note that the fishing/hunting level indicator and moon phase indicator are all based
on calculated values. They are provided only for reference purposes.

• See the “Timekeeping” section of this manual for information about setting the
current time and date, and about specifying your Home Site.

Home Site Data

Moon phase, the fishing/hunting level indicator, and Fishing/Hunting Mode data will
not be displayed properly unless Home Site data (UTC differential and longitude) is
configured correctly.

• The UTC differential is a value that indicates the time difference between a
reference point in Greenwich, England and the time zone where a city is located.

• The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds
are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

• The “Site Data List” at the back of this manual provides UTC differential, latitude,
and longitude information around the world.

• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch, and whenever you have the battery replaced. Change
these settings to match the area where you normally use the watch.
