Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual and keep it on hand for later reference
when necessary.
• The longitude, lunitidal interval, Moon phase indicator, and tide graph data that
appear on the display of this watch are not intended for navigation purposes.
Always use proper instruments and resources to obtain data for navigation
purposes.
• This watch is not an instrument for calculating low tide and high tide times. The
tide graph of this watch is intended to provide a reasonable approximation of tidal
movements only.

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,
20 minutes)
