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.

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.

To view point data

1. In the Timekeeping Mode, press that appears is the one you selected as your home time point.

Home time

This watch comes pre-programmed with data for 10 dolphin or whale watching 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” 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

ABOUT THE BACKLIGHT

About the Auto Light Switch Function

When the auto light switch function 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 approximately 40 degrees causes the backlight to illuminate.

Parallel to ground 40

• 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 auto 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 or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

To switch the auto light switch function on and off

In the Timekeeping Mode, hold down switch function on and off.

• The auto light switch indicator is shown on the display in all modes while the auto light switch function is on.

• In order to protect against running down the battery, the auto light switch function is automatically turned off approximately six hours after you turn it on. Repeat the above procedure to turn the auto light switch function back on if you want.

• Pressing Sunset Mode, Alarm Mode) or 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 backligfht shortens the battery life.

• The watch emits an audible sound whenever the display is illuminated. This is

because the EL light vibrates slightly when lit. It does not indicate malfunction of the watch.

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.
