•Pressing
DD
DD
D toggles between display of the month and day, and display of the day
of the week and day.
•For normal timekeeping, you need to set the time, and date, and turn daylight sav-

•To use the Tide Graph functions, you must set the GMT differential, your current
longitude, and the lunar tide interval on your point.
To set the time, date, GMT differential, longitude and lunar tide interval

Important!
•Be sure to use DST on/off setting to turn daylight saving time (summer time) on
and off. Never manually change the timekeeping setting to adjust for daylight sav-
ing time. Doing so will produce incorrect Tide Graph and Moon Age.
•The GMT differential is the difference in time between the time zone where you are
currently located and Greenwich Mean Time (GMT).
•See “TIME ZONE CHART” at the back of this manual for information about deter-
mining the GMT differential in your area.
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.

1.Press
DD
DD
D to scroll through the data for the 11 points.
This watch comes pre-programmed with data for 10 dol-
phin or whale watching points around the world. The data
for each point includes an 3-character point name, GMT
differential, longitude, and lunar tide interval. Setting the
current time for normal timekeeping causes the time set-
tings for all points to be adjusted accordingly. In the case
of DST, however, you must make a separate setting for
each point.
You can also input GMT differential, longitude, and lunar
tide interval on one additional point of your own. The point
name for this data is “ORG” and the name cannot be
changed.
•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.
