Using Moon Data
The Moon Age Mode displays a value that indicates the current date’s Moon age. The value
indicates the Moon age at sunset on the current date.
To look up the Moon age on a specifi c date
1. In the Timekeeping Mode, press
C
twice to enter Moon Age Mode.
• This will cause MOON AGE to appear on the digital display for
about one second. After that the current year, month, and day
appears for about one second.
• Next, CALC will appear on the digital display indicating that
Moon age calculation is in progress. After the calculation is
complete, the Moon age value for the current date will appear.
2. While a Moon age value is displayed you can use the
D
(+) and
B
(–) buttons to scroll from day to day.
•
Scrolling to another day will cause CALC to appear on the digital
display for one second indicating that Moon age calculation is in
progress. The Moon age for the selected data will appear when
calculation is complete.
•
Hold down
C
for two seconds to return to the Timekeeping Mode.
Note
• Moon age is calculated to an accuracy of ±1 day.
Moon Data
The Moon age information that appears when you enter the Moon Age Mode is for sunset on the
current date as kept in the Timekeeping Mode in accordance with your Home City setting. After
that, you can scroll to another date and check the Moon age on that date.
• If the Moon data is not correct, check your Timekeeping Mode settings and correct them if
necessary.

Thermometer
This watch uses a temperature sensor to take temperature readings.
To enter and exit the Thermometer Mode
1. In the Timekeeping Mode, press
C
three times to enter
Thermometer Mode.
• This will cause THERMO to appear on the digital display for
about one second indicating that temperature readings are
being taken. After that, the measurement result will appear.
• The watch will take a temperature reading every fi ve seconds for
one or two minutes.
2. Hold down
C
for about two seconds to return to the Timekeeping
Mode.
• If you do not perform any button operation for one or two
minutes after temperature measurement is complete, the watch
will automatically return to the Timekeeping Mode.
Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to
--.-
°C (or °F) if a measured temperature falls
outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear
as soon as the measured temperature is within the allowable range.
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To
specify temperature unit” (page E-40) for more information.

Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no further
adjustment. If you notice serious errors in the temperature readings produced by the watch, you
can calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and accurate
thermometer.
– If adjustment 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.
To correct the temperature value
1. You can correct the temperature readings displayed by the watch in
accordance with another measuring instrument for more accurate
readings.
2. In the Timekeeping Mode, press
C
three times to enter
Thermometer Mode.
3. Hold down
A
until the current temperature value fl ashes on the
digital display. This is the setting screen.
4. Use
D
(+) and
B
(–) to calibrate the temperature value with the reading of another instrument.
• Each press of a button changes the temperature value in units of 0.1°C (0.2°F).
• To return the currently fl ashing value to its initial factory default setting, press
B
and
D
at
the same time. OFF will appear at the fl ashing location for about one second, followed by
the initial default value.
5. Press
A
to return to the Thermometer Mode.

Thermometer Precautions
• 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 all moisture from the case. It takes approximately 20 to 30 minutes for the case of the
watch to reach the actual surrounding temperature.
• When taking temperature readings, it is best to remove the watch from your wrist in order to
eliminate the effects of body heat. Remove the watch from your wrist and allow it to hang freely
from your bag or in another location where it is not exposed to direct sunlight.
