Home Site Data
Moon phase, tide graph data, and Tide/Moon Data Mode data will not be displayed
properly unless Home Site data (UTC differential, longitude and lunitidal interval) is
configured correctly.
• The UTC differential indicates the time differential with Greenwich, England.
• 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.
• Depending on the model of your watch, display text
(Light)
appears either as dark figures on a light background
(Module 4335), or light figures on a dark background
(Module 4348). All sample displays in this manual are
shown using dark figures on a light background.
• Button operations are indicated using the letters shown
in the illustration.
• For the sake of simplicity, the sample displays in this
manual do not show the analog hands of the watch.
• Each section of this manual provides you with the
information you need to perform operations in each
