Home Site Data
Moon phase, the fishing level indicator, and Fishing/Moon 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 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.
UTC differential (+9.0); Longitude (East 140 degrees)
