This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as
shown below.

• The Moon phase indicator shows the Moon as viewed at noon from a position in the
Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
• The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon
appears to wax and wane as the relative positioning of the Earth, Moon, and Sun
changes. The greater the angular distance between the Moon and the Sun,* the more
we see illuminated.
* The angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
This watch performs a rough calculation of the current Moon age starting from day 0
of the moon age cycle. Since this watch performs calculations using integer values
only (no fractions), the margin for error of the displayed Moon age is ± 1 day.
Thermometer
Temperature Sensor Calibration
The temperature sensor built into the watch 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 calibrate the temperature sensor
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. Press C nine times to display the temperature sensor
calibration screen.
3. Use D (+) and B (–) to change the calibration value.
• You can change the value in 0.1°C (0.2°F) steps, in a
range of ±10°C (±18°F). The calibration value shows
Calibration value
''--.-'' when the setting is outside the allowable range.
• To return the calibration value to its default (no calibration, indicated by ''- -''),
press D and B at the same time.
• Temperature sensor calibration will not be possible if the current reading is
outside the allowable display range (–10.0°C/14.0°F to 60.0°C/140.0°F) and the
calibration value shows ''- -''.
• Setting a sensor calibration value does not affect temperature values that are
already stored in memory.
4. After configuring the setting you want, press A twice to exit the setting screen.
To specify the temperature display unit
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. Press C 10 times to display the temperature unit
setting screen.
3. Use D to switch between Celsius (
(
).
• The initial factory default and the initial default after
Temperature unit
battery replacement is Celsius (
4. After configuring the setting you want, press A twice to exit the setting screen.
• The temperature display unit setting you select is also applied to temperature values
that are already stored in memory.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch's buttons. You can turn the button operation
tone on or off as desired.
• Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the
Mute indicator
display), hold down C to toggle the button operation tone
on (mute indicator not displayed) and off (mute indicator
displayed).
• Since the C button is also the mode change button, holding it down to turn the
button operation tone on or off also causes the watch's current mode to change.
• The mute indicator is displayed in all modes when the button operation tone is
turned off.

).
Auto Return Feature
• If you leave a screen with flashing digits on the display without performing any
operation for two or three minutes, the watch saves any settings you have made up
to that point and exits the setting screen automatically.
• The watch will change to the Timekeeping Mode automatically if you do not perform
any operation in the Fishing Mode, Temperature Data Recall Mode, Alarm Mode, or
Hand Setting Mode for two or three minutes.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and the A (AM) indicator appears for times in the range
of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The year can be set in the range of 2000 to 2099.
• The watch's built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch's batteries replaced.
World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• All World Time Mode times are calculated from the current time in the Timekeeping
Mode using UTC time differential values.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long use.
• Illumination may be hard to see when viewed under direct sunlight.
• 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.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the batteries.
