either of two different transmitters for reception.
• For information about selecting a Home City, see "Setting the
Time and Date Manually".

the Home City, and AT (auto select) for the transmitter selection
mode.

Calibration Signal Reception

Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Receipt of a calibration signal causes the digital time to be adjusted
first, followed by adjustment of the analog time. In order to ensure
correct ajustment of the analog time, be sure to match the analog time
with the digital time before performing a signal receive operation.
• Note that analog timekeeping is not performed during signal
reception, so the time indicated by the analog hands may be
wrong.
• Operating any button while auto reception is in progress will
cause the watch to beep and then exit the receive operation.
• Make sure you are within the range of the calibration signal
transmitter before performing the reception operation. Remember
that geographic contours, nearby buildings, the season, the time
of day, can make reception impossible even when you are within
range of the transmitter.
• Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
• This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States only. Note that you will need to make your own
adjustments when using this watch outside of Japan or the United
States, or in any area that is outside the range of one of the
receivable time calibration signal transmitters.
• When the watch is unable to adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is within
±
15 seconds per month.
• Strong electrostatic charge can cause timekeeping error.
• Signal reception is cancelled if an alarm starts to sound while it is
being performed.
• The watch's calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.

settings, described below.
• AT
With this setting, the watch automatically selects either the Mt.
Otakadoya signal (40kHz) or the Mt. Hagane signal (60kHz),
whichever is strongest.
• 40 JPN
With this setting, the watch always receives the Mt. Otakadoya
signal (40kHz).
• 60 JPN
With this setting, the watch always receives the Mt. Hagane
signal (60kHz).

When the setting you want is displayed, press the A
button twice to exit the setting screen.
• At this time, the analog hands will adjust automatically to the
digital time.
• The display also will exit the setting screen automatically if
you do not perform any operation for about two or three
minutes.
Troubleshooting
Cannot perform manual reception.
Cause:
• Manual receive can be performed in the
Timekeeping Mode only.
• The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
(Chicago), DEN (Denver), or LAX (Los
Angeles).
Corrective Measures: • Perform manual receive in the
Timekeeping Mode.
• Change the Home City to TYO (Tokyo),
NYC (New York), CHI (Chicago), DEN
(Denver), or LAX (Los Angeles).
Correctly set the Home City as detailed
under "Setting the Time and Date
Manually".
The
icon is not on the display even though auto signal
reception is turned on.
Cause:
• The
icon appears after the watch
successfully receives the calibration signal
and adjusts the current time setting.
• A single receive operation was not
successful.
• The watch is not in the Timekeeping
Mode or World Time Mode when an auto
reception time is reached.
Corrective Measures: • Check to make sure the watch is in a
location where it can receive the signal.
• Place the watch in a location where
reception conditions are good.
• Make sure that the watch is in the
Timekeeping Mode or World Time Mode
during the auto reception times.
• You performed manual reception, which
clears the
icon from the display.

off.
• On
Auto receive is turned on.
• OF
Selecting this setting turns off auto receive and auto
transmitter selection.
Time setting is incorrect following signal reception.
Cause:
• If the current time is advanced by one
hour, it probably means that summer time
is turned on (indicated by the DST
indicator on the display).
• If there is a large error in the setting, it
probably means that the wrong Home
City is selected.
Corrective Measures: • Correctly configure the summer time and
Home City settings as detailed under
"Turning Summer Time On and Off" and
"Setting the Time and Date Manually".
• If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup
of the watch.
• The following are the watch's factory default settings, which
are configured automatically whenever you have the
battery of the watch replaced.
