TIMEKEEPING MODE
The settings you make in the Timekeeping Mode are very important, because they
affect the Moon Data, Tide Graph, and Sunrise/Sunset functions.
There are three setting screens in the Timekeeping Mode: the Time and Date Setting
Screen, DST, GMT Differential, Point Name Setting Screen, and Longitude/Latitude,
Lunar Tide Interval Setting Screen.
• For normal timekeeping, you need to set the time, and date, and turn daylight
saving time (summer time) on or off.
• To use the Moon Data, Tide Graph, and Sunrise/Sunset functions, you must set the
GMT differential, your current longitude and latitude, and the lunar tide interval on
your point.
• If you do not operate any button for a few minutes while a selection is flashing, the
flashing stops and the watch goes back to the Timekeeping Mode automatically.
To set the time and date
• Use this screen to set the current time and date, to
reset the seconds to 00, and to toggle between 12-hour
and 24-hour timekeeping.
1.In the Timekeeping Mode, check if the DST indicator is
displayed, and change the DST setting in accordance

About the lunar tide interval
The lunar tide interval is the period from the moon’s upper transit (moon up) to high
tide. If you know the lunar tide interval, tide changes can be determined using the
moon age. This watch calculates tide changes according to the current time and the
location setting, and displays them graphically.
To calculate the lunar tide interval
1.Look up the high tide time for the flood tide of the location whose tide changes you
want to know.
2.Use this watch to look up the moon up time that occurs immediately before this
time.
3.
Subtracting the moon up time from the high tide time produces the lunar tide interval.
MULTI-TIME MODE

• Pressing
CC
CC
C at any time in the Multi-time Mode immediately returns to the Time-
keeping Mode.
• You can use the procedure under “DST, GMT Differential, Point Name Setting
Screen” and “Longitude/Latitude, Lunar Tide Interval Setting Screen” to change
the name and other data of a point.
This watch comes pre-programmed with data for 10 fishing points around the world.
The data for each point includes an 8-character point name, GMT differential, longi-
tude and latitude, and lunar tide interval. Setting the current time and date for any of
the points causes the time and date settings for all other points to be adjusted ac-
cordingly. In the case of DST, however, you must make a separate setting for each
point. You can use the following procedure to select any one of the ten points as your
home time point.
• See the “PRESET LOCATION CHART” at the back of this manual for details on
the locations whose data is preset in watch memory when you purchase it.
To select a point for your home time
• While the point you want to use for your home time is displayed in the Multi-time
Mode, hold down
DD
DD
D for about two seconds.
