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.

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.
Subtracting the moon up time from the high tide time produces the lunar tide interval.
3.
Use this screen to specify the longitude, latitude, and
lunar tide interval of your current location.

Press B.
Point name
This watch comes pre-programmed with data for 10 surfing points around the world.
The data for each point includes an 8-character point name, GMT differential,
longitude 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
accordingly. 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” 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 E for about two seconds.

ABOUT THE BACKLIGHT
About the Auto Light Switch
When the auto light switch is turned on, the backlight automatically turns on for two
seconds under the conditions described below. Avoid wearing the watch on the inside
of your wrist. Doing so causes the auto light switch to operate when not needed,
which shortens battery life.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to illuminate.

• Press E (forward) or B (back) within about two
seconds after entering the Moon Data Mode to scroll to
another point. It takes a few minutes before moon data
appears after you display the name of a point.
• If you do not perform any button operation, about two
seconds after you enter the Moon Data Mode the
display changes automatically to show the moon data
for today’s date. Pressing E advances to the next date,
while B goes back to the previous date. Holding down
either button scrolls the date at high speed. It takes a
few minutes before moon data appears after you display
a date.
• The backlight may not illuminate if the face of the watch is more than 15 degrees off
parallel to the left or right. Make sure that the back of your hand is parallel to the
ground.
Parallel to ground
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch function. If the backlight does not illuminate, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back toward you
again. If this does not work, drop your arm all the way down so it hangs at your side,
and then bring it back up again.
• Under certain conditions the backlight may not light until about one second after you
turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down E for one or two seconds to turn the auto light
switch function on and off.
ON OFF
• The auto light switch indicator is shown on the display in all modes while the auto
light switch is on.
• In order to protect against running down the battery, the auto light switch is
automatically turned off approximately six hours after you turn it on. Repeat the
above procedure to turn the auto light switch back on if you want.
• Pressing D (Timekeeping Mode, Moon Data Mode, Tide Graph Mode, Sunrise/
Sunset Mode, Alarm Mode) or E (Countdown Timer Mode, Stopwatch Mode)
illuminates the display, regardless of the auto light switch’s on/off setting.
Caution
• The backlight of this watch employs an electro-luminescent (EL) light, which loses
its illuminating power after very long term use.
• Frequent use of the backlight shortens the battery life.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
Warning!
• Never try to read your watch when mountain climbing or hiking in areas that
are dark or in areas with poor footing. Doing so is dangerous and can result in
serious personal injury.
• Never try to read your watch when running where there is the danger of
accidents, especially in locations where there might be vehicular or
pedestrian traffic. Doing so is dangerous and can result in serious personal
injury.
• Never try to read your watch when riding on a bicycle or when operating a
motorcycle or any other motor vehicle. Doing so is dangerous and can result
in a traffic accident and serious personal injury.
• When you are wearing the watch, make sure that its auto backlight function is
turned off before riding on a bicycle or operating a motorcycle or any other
motor vehicle.
Sudden and unintended operation of the auto backlight can create a
distraction, which can result in a traffic accident and serious personal injury.
