setting and Home City setting.
If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup

Troubleshooting
Cannot perform manual reception.
Possible Cause:
The watch is not in the Timekeeping Mode
or World Time Mode.
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 reception while a time
screen is on the display in the Timekeeping
Mode or World Time Mode only.
Change Home City To TYO (Tokyo), NYC
(New York), CHI (Chicago), DEN
(Denver), or LAX (Los Angeles).
The icon is not displayed even though auto reception is
turned on.
Possible Cause:
A single receive operation was not
successful.
Both the hour-minute-second group and
year-month-day group were not received.
The watch is not in the Timekeeping Mode
or World Time Mode when an auto
reception time is reached.
You performed manual reception, which
clears the icon from the display.
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.
The icon disappears from the display
whenever you change the current time
setting manually.
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 receive operation. Remember
that geographic contours, nearby buildings, the season, and 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 signals 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.
If only the hour-minute-second group is received, the Timekeeping
Mode date at the time of reception is recorded as the last
reception date.
