ABOUT THE BA CKLIGHT

• While in the Timekeeping Mode, press B to illuminate the display.

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.

• Press C to change from mode to mode.

• After you perform an operation in any mode, pressing C returns to the Timekeeping Mode.

THERMOMETER FUNCTIONS

A built-in temperature sensor measures temperature and shows the measured value on the
display.The thermometer can be calibrated to correct for errors.

Important

Temperature measurements are affected by your body temperature (while you are wearing the
watch), direct sunlight, and moisture.To achieve a more accurate temperature measurement,
remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and
wipe off all moisture from the case.It takes approximately 20 to 30 minutes for the case of the
watch to reach the actual surrounding temperature.

Accurate temperature measurements cannot be achieved while you are wearing the
watch.The following graph illustrated affects of body temperature on actual
temperature.

About Temperature Measurement

Temperature measurements are taken automatically every two minutes, regardless of what
mode the watch is in.You can see the measured values in the Timekeeping Mode’s Temperature
Display.

Understanding the temperature display

1.Use C to enter the Timekeeping Mode.

2.Press D to display the Temperature Display.

• Whenever you switch to the Temperature Display, the current
temperature is measured and displayed.

* The display shows “ – .– °C”if a measured value falls

outside the range of –20°C to 60°C.The normal display will
return as soon as the temperature returns within the
allowable range.

Calibrating the Temperature Measurement

The temperature sensor of this watch is calibrated at the factory before shipment and further
adjustment is normally not required. If noticeable error is found in the temperature readings
produced by the watch, you can adjust it to correct the error.

Important

Incorrectly calibrating the temperature measurement of this watch can result in incorrect
readings.Carefully read the following before doing anything.

• Compare the readings produced by the watch with those of another reliable, accurate
thermometer.

• If calibration is required, remove the watch from your wrist and wait for 20 or 30 minutes to
give the temperature of the watch time to stabilize.

• Perform the temperature calibration before procedure as quickly as possible to avoid the
temperature of the watch being affected by your body temperature.

• You can also preform temperature calibration underwater, if the water temperature is stable.

To calibrate the temperature

1.Use C to enter the Timekeeping Mode and press D to
display the Temperature Display.

2.Holding down A and the current temperature digits flash.

3.Each press of D increase the displayed temperature by

0.1°C, and pressing the B decrease it by 0.1°C.

• You can calibrate the temperature within a range of –9.9°C
to +9.9°C.

• Press B and D at the same time to rest the temperature
calibration to the factory setting.

4.After calibrating the temperature, press A to return to the
Temperature Display.

MOON DATA MODE

Be sure to set the current time and your current location before trying to use the Moon Data
Mode.
The Moon Data Mode display shows the current moon age, as well as moon up and moon down
times.Moon age is indicated both by a value and one of the following graphics.

• The moon up time indicates when the moon will reach
its highest point relative to your current location (upper
transit), while the moon down time indicates when it will
reach its lowest point (lower transit).Note that moon up
and moon down times are accurate up to ±30 minutes.

You can use the key operation below to look up the moon age and the moon up and moon down
times for any date from January 1, 1995 to December 31, 2039.

TIDE GRAPH MODE

Before using the Tide Graph Mode, be sure to first carefully set the current time, your current
location, and the lunitidal interval.

About the lunitidal interval

The lunitidal interval is the period from the moon's upper transit (moon up) to high tide.If you
know the lunitidal 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 lunitidal 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 lunitidal interval.

To set the lunitidal interval

1.In the Moon Data Mode, hold down A until both sides of the
Tide Graph and hour digits start to flash, as shown below.

• You can also start this procedure by holding down A while
in the Tide Graph Mode.

2.Use C to select the digit whose setting you want to change.
Each press of C moves the flashing to the next digit.

3.Use D to increase the flashing digit or B to decrease it.
Holding down either button changes the setting at high
speed.

4.After you are finished making the lunitidal setting you want,
press A to enter the Tide Graph Mode.

About the Tide Graph Mode

The Tide Graph Mode shows the changing of the tides in graphic form.The graph uses time
(advancing from left to right) as the horizontal axis, and tide change as the vertical axis.

• You can enter the Tide Graph Mode by pressing A while in the Moon Data Mode.Though you
can change the time setting while in the Tide Graph Mode, you cannot change the month or
day setting.To display the tide graph for another date, return to the Moon Graph Mode,
change the date setting, and then enter the Tide Graph Mode again.Also note that you
cannot directly change the month setting in the Moon Data Mode.The month setting changes
automatically as you increase or decrease the day setting.

• The Tidal Graph is also on the display in the Timekeeping Mode, where it indicates the tide for
the current time.
