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 no 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 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is applied in all modes.
•
The year can be set in the range of 2000 to 2039.
•
The watch’s built-in full automatic calendar automatically makes allowances
for different month lengths and leap years. Once you set the date, there
should be no reason to change it except when battery power drops to Level
4.
Setting the Analog Time
Perform the procedure below when the time indicated by the analog hands
does not match the time of the digital display.

Digital Compass
A built-in bearing sensor detects magnetic north. The watch uses this data to
display an angle value and four pointers indicating north, south, east, and
west. Direction readings are performed in the Digital Compass Mode.
•
You can calibrate the bearing sensor if you suspect the direction reading is
incorrect.
To enter and exit the Digital Compass Mode
1. While in the Timekeeping, Barometer/Thermometer, or Altimeter Mode,
press
C
to enter the Digital Compass Mode.
•
At this time, the watch immediately starts a Digital Compass operation.
After the first reading is obtained, the watch continues to take direction
readings automatically each second, for up to 20 seconds.
2. Press
D
to return to the Timekeeping Mode.
To take a direction reading
1. Enter the Digital Compass Mode.
2. Place the watch on a flat surface or (if you are
wearing the watch), make sure that your wrist
is horizontal (in relation to the horizon).
3. Point the 12 o’clock position of the watch in
the direction you want to measure.
4. Press
C
to start a Digital Compass
measurement operation.
•
After direction measurement is complete, an
angle value appears on the display. The angle
value indicates the clockwise angle formed
between magnetic north (which is 0 degrees)
and the direction that the 12 o’clock position of
the watch is pointing.
•
Also, four pointers appear to indicate magnetic
north, south, east, and west.
•
After the first reading is obtained, the watch
continues to take direction readings
automatically each second, for up to 20
seconds.

Note
•
Note that taking a measurement
while the watch is not horizontal
(in relation to the horizon) can
result in large measurement
error.
•
Any ongoing direction measurement operation is temporarily paused while
the watch is performing an alert operation (alarm or hourly time signal) or
while the watch’s backlight is turned on (by pressing
L
). The measurement
operation resumes for its remaining duration after the operation that caused
the pause is finished.
•
See “Digital Compass Precautions” for other important information about
taking direction readings.
Barometer/Thermometer
This watch uses a pressure sensor to measure air pressure (barometric
pressure) and a temperature sensor to measure temperature.
•
You can calibrate the temperature sensor and the pressure sensor if you
suspect that readings are incorrect.
To take barometric pressure and temperature readings
Pressing
B
in the the Timekeeping Mode or in any of the other sensor
modes enters the Barometer/Thermometer Mode and automatically starts
taking barometric pressure and temperature measurements.

Temperature and
Barometric Pressure
•
It can take up to four or five seconds for the barometric pressure reading to
appear after you enter the Barometer/Thermometer Mode.
•
Barometric pressure is displayed in units of 1hPa.
•
The displayed barometric pressure value changes to
xxxx
hPa if a
measured barometric pressure falls outside the range of 260 hPa to 1100
hPa. The barometric pressure value will be displayed again as soon as the
measured barometric pressure is within the allowable range.
•
Temperature is displayed in units of 0.1
°
C.
•
The displayed temperature value changes to
xx
.
x
°
C if a measured
temperature falls outside the range of –10.0
°
C to 60.0
°
C. The temperature
value will be displayed again as soon as the measured temperature is
within the allowable range.
•
Some countries refer to the barometric pressure unit hecto-pascal (hPa) as
millibars (mb). It really makes no difference, because 1hPa = 1mb.
•
See “Barometer and Thermometer Precautions” for important precautions.
Barometric Pressure History Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
The barometric pressure history graph contains points that show you the
changes in barometric pressure readings taken by the watch for up to the last
18 hours. The time line along the bottom of the graph runs from left to right,
which means that the rightmost point on the graph is the latest reading. The
relative positions of the points on the graph indicate whether barometric
pressure is rising, falling, or holding relatively steady.
•
No point is plotted on the graph whenever a measurement operation fails
due to sensor malfunction, low battery power, or any other reason.
Relatively steady (within ±
3hPa)
Rising (rise greater than 3hPa)
Falling (fall greater than 3hPa)
The following shows how to interpret the data that appears on the barometric
pressure history graph.
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
To adjust the analog time
1. In the Timekeeping Mode, press
D
four times
to enter the Hand Setting Mode.
2. Hold down
A
until the current digital time
starts to flash, which indicates the analog time
setting screen.
3. Press
E
to advance the analog time setting by
20 seconds.
•
Holding down
E
advances the analog time setting at high speed.
•
If you need to advance the analog time setting a long way, hold down
E
until the time starts advancing at high speed, and then press
B
.
This locks the high-speed hand movement, so you can release the two
buttons. High-speed hand movement continues until you press any
button. It will also stop automatically after the time advances 12 hours
or if an alarm starts to sound.
4. Press
A
to exit the setting screen.
•
To return to the Timekeeping Mode, press
D
.
•
During measurement the watch displays an angle value and four direction
pointers of the first reading, which change dynamically when the watch is
moved. After measurement is complete, the angle value and four direction
pointers are frozen in accordance with the last measurement.
•
The indicator flashes on the display while a measurement is in progress.
About Barometric and Temperature Measurements
•
Barometric pressure and temperature measurement operations are
performed as soon as you enter the Barometer/Thermometer Mode. After
that, barometric pressure and temperature measurements are taken every
five seconds for the first three minutes.
•
The indicator to the left of “BAROMETER” on the display flashes while a
measurement is in progress.
•
The barometer automatically takes measurements every three hours
(starting from midnight), regardless of what mode you are in. The results of
these measurements are used for plotting points on the barometric
pressure history graph.
•
You can also perform a barometric pressure and temperature measurement
at any time by pressing
B
in the Barometer/Thermometer Mode.
