Home Site Data
Moon phase, tide graph data, and Moon/Tide Data Mode data will not be displayed properly unless Home Site data (GMT differential, longitude, and lunitidal interval) is configured correctly.
•The GMT differential is the time difference of the time zone where the site is located from Greenwich Mean Time.
•Note that you must add one hour to the GMT differential for your time zone whenever you change to Daylight Saving Time. Subtract one hour when you change back to Standard Time.
•The lunitidal interval is the time elapsing between the Moon’s transit over a meridian and the next high tide at that meridian. See “Lunitidal Interval” for more information.
•This watch displays lunitidal intervals in terms of hours and minutes.
•The “Site Data List” and “Lunitidal Interval List” provide GMT differential, longitude, and lunitidal interval 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.
GMT differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours,
