Viewing the Latest Signal Reception Results
You can use the procedure below to check whether or not the last signal receive
operation was successful.
To check the latest signal reception results
In the Timekeeping Mode, press A.
• If the watch was able to perform a successful signal
receive operation during the last receive period, the
stopwatch second hand will move to Y (YES).
If the watch has been unable to receive any signal
successfully, the stopwatch second hand will move to
N (NO).
• The watch will return to the Timekeeping Mode after five
seconds or when you press A.
• The current receive result is cleared when the first auto receive operation is
performed on the following day. This means Y (YES) indicates successful signal
reception since the start of the current day.
• If you adjust the time or date setting manually, the stopwatch second hand will move
to N (NO).

Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
• For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Atomic Timekeeping Precautions”.
• You changed the time setting
manually.
•
You performed some button operation
during the auto receive operation.
• The stopwatch is performing an
elapsed time measurement operation.
• Signal reception results are reset at
the first time of the next receive
period.
• The Home City setting is not correct
for the area where you are using
the watch.
• The home position of the hands is off.
The

following
signal
reception.
• Perform manual signal
receive or wait until the next
auto signal receive operation
is performed.
• Stop the stopwatch operation.
• Check to make sure the
watch is in a location where it
can receive the signal.
• Select the correct Home City.
• Enter the Home Position
Adjustment Mode and adjust
the home position.
What you should doProblem Probable Cause
Stopwatch
The stopwatch lets you measure elapsed time.
• When you enter the Stopwatch Mode, the stopwatch
1/20 second hand and the stopwatch minute hand move
to 0.
• You can start elapsed time measurement with the
stopwatch while the watch is in the Stopwatch Mode or
the Timekeeping Mode.
• The display range of the stopwatch is 59 minutes, 59.95
seconds.
• The stopwatch continues to run, restarting from zero
after it reaches its limit, until you stop it.
• You cannot switch to another mode while a stopwatch
elapsed time operation is in progress.

To start an elapsed time operation while in the Stopwatch Mode
1. In the Stopwatch Mode, press B to start elapsed time measurement.
2. Press B to stop elapsed time measurement.
• You can restart and stop elapsed time measurement as many times as you like by
pressing B.
• The 1/20 second hand rotates during the first 60 seconds only, and then stops.
When elapsed timing is stopped (by pressing B), the 1/20 second hand jumps to
the 1/20 second indication (which is kept internally).
3. Check the elapsed time.
• After you are finished measuring elapsed time, press D to reset the stopwatch to all
zeros. The stopwatch will reset to all zeros even if you press D while elapsed time
measurement is in progress.
• To return to the Timekeeping Mode, press D while the stopwatch is reset to all
zeros.
To start an elapsed time operation while in the Timekeeping Mode
1. In the Timekeeping Mode, press B to start elapsed time measurement.
• After pressing B in the Timekeeping Mode, elapsed time measurement will not
start for about one second.
• The elapsed time operation will not start if you press B in the Timekeeping Mode
while either of the following conditions exists.
When an alarm is turned on
While the watch is changing from one date to the next (at midnight)
2. Press B to stop elapsed time measurement.
• You can restart and stop elapsed time measurement as many times as you like by
pressing B.
• The 1/20 second hand rotates during the first 60 seconds only, and then stops.
When elapsed time measurement is stopped (by pressing B), the 1/20 second
hand jumps to the 1/20 second indication (which is kept internally).
3. Check the elapsed time.
• After you are finished measuring elapsed time, press D to reset the stopwatch to all
zeros. The stopwatch will reset to all zeros even if you press D while elapsed time
measurement is in progress.
• To return to the Timekeeping Mode, press D while the stopwatch is reset to all
zeros.
Tide Graph
The Tide Graph calculates and graphically represents
current tide conditions in your Home City or a port city in
the vicinity of the Home City based on longitudes, lunar
day length, and lunitidal interval preset in watch memory,
and on high tide times specified by you.
• When you enter the Tide Graph Mode, the tide graph
moves to the current tide position and stops there.
• Before you can use the Tide Graph to check tide
conditions, you must first correctly specify the high tide
time for the area you want to check. For details about
specifying the high tide time, see “To specify the current
time as the high tide time” below or “To specify another
time as the high tide time”.
• For information about Home Cities and port cities in the
vicinity of the Home City, see “Lunitidal Intervals for
Each City”.

• The “Lunitidal Intervals for Each City” shows the lunitidal interval data that is preset
in watch memory. The city codes shown in this table do not necessarily match the
city codes that are preset in watch memory.
• All of the operations in this section are performed in the Tide Graph Mode.
To specify the current time as the high tide time
In the Tide Graph Mode, hold down B for about two
seconds until the watch beeps twice.
• This will set the current time as the high tide time, and
cause the day of the week hand to move to the high tide
position.

To specify another time as the high tide time
1.In the Tide Graph Mode, hold down A for about two
seconds until the watch beeps. This indicates the watch
is in the setting mode.
• The day of the week hand will move to the Tide Graph
high tide position.
•
At this time, the hour, minute, and 24-hour hands will
indicate the current high tide time setting for the
currently selected Home City or a port city in the vicinity
of the Home City. The second hand will stop at “0”.
*
* Some models show “60” instead of “0”.
2. Use D (+) and B (–) to change the high tide time setting.
• Each press of the buttons moves the minute hand one minute.
• As you set the time, take care to ensure that the 24-hour hand also is at the
correct position.
3. After the setting is the way you want, press A to exit the setting mode and return to
the Tide Graph Mode.

To return the high tide time to its initial factory default setting
1.In the Tide Graph Mode, hold down A for about two
seconds until the watch beeps. This indicates it is in the
setting mode.
• The day of the week hand will move to the Tide Graph
high tide position.
•
At this time, the hour, minute, and 24-hour hands will
indicate the current high tide time setting for the
currently selected Home City or a port city in the vicinity
of the Home City. The second hand will stop at “0”.
*
* Some models show “60” instead of “0”.
2. Press D and B at the same time to return the high tide time to its initial factory
default setting.
• At this time, the hour, minute, and 24-hour hands will indicate the default high tide
time setting for the currently selected Home City.
3. After the setting is the way you want, press A to exit the setting mode and return to
the Tide Graph Mode.
