• If only hour, minute, and second data (no date data) is received,
the last reception date shows the date that the receive operation
was performed (as kept in the Timekeeping Mode).
• Make sure that the watch is in the
Timekeeping Mode or World Time Mode
during the auto reception times.
• Note that manual reception also clears
the “ ” icon from the display.
Time setting is incorrect following signal reception.
Cause: • Summer time is turned on or the wrong
Home City is selected.
Corrective Measures: • If the time is advanced by one hour, it
probably means that summer time
(indicated by the DST indicator on the
display) is turned on. If the time is off by
more than one hour, it probably means
that the Home City is selected. Correctly
configure the summer time and Home
City settings as detailed under “To
manually set the time and date”.
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.

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 Home City to TYO (Tokyo), NYC
(New York), CHI (Chicago), DEN
(Denver), or LAX (Los Angeles). For
details, see “To manually set the time and
date”.
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 and date settings.
• A single receive operation was not
successful.
• The “ ” icon is displayed only when both
the hour-minute-second group and year-
month-day group were received. It will
not remain on the display if only the hour-
minute-second group is received.
• 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.
Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• 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 even 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 built-in calendar runs up to the year 2039. Signal
reception after that causes an error, and the date remains
displayed as December 31, 2039.
