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

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.

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.
To display the moon up and moon down time for a specific date
1.Use C to enter the Moon Data Mode.
• When you enter the Moon Data Mode from
another mode, the display shows the moon up
and moon down times for the current date (as
kept in the Timekeeping Mode).
2.Press D to advance the date or B to move
back. Holding down either button changes the
date at high speed.
3.When the date you want is displayed, you will
have to wait for about 2 seconds as the watch
performs its internal calculation before displaying
the moon up and moon down time for that date.
• 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.

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.

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.
T
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.
