Troubleshooting
Cannot perform manual reception.
Cause: • Manual receive can be performed in the
Timekeeping Mode only.
• Manual receive cannot be performed
while a timer operation is in progress.
• 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 “Configuring Home Time Settings”.
The receive indicator is not on the display even though auto
signal reception is turned on.
Cause: • The receive indicator 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.
• You performed manual reception, which
clears the receive indicator 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.
Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Signal reception is not performed while a timer operation is being
performed.
• When a time calibration signal is received, the watch corrects its
digital time setting first, and then adjusts the analog time setting
accordingly. In order to ensure that the analog time matches the
digital time, make sure you adjust the analog time to match the
digital time before signal reception is performed.
• Pressing 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, seasonal conditions,
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. It operates like a standard (non-radio
controlled) watch outside of the range 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.
World time lets you display the current time in any one of 30 cities
(29 time zones) around the world.
• When you enter the World Time Mode, the screen for the city that
was displayed when you last exited the mode appears first.
• The seconds count in the World Time Mode is linked with the
Timekeeping Mode seconds count.
• The same 12-hour/24-hour format you select for the Timekeeping
Mode time is also applied in the World Time Mode.
Important!
If the World Time Mode time is incorrect, correct the setting of the
current time in the Timekeeping Mode.
• For information about selecting a Home City, see “Configuring
Home Time Settings”.

World Time Mode
Using Summer Time (DST)
Summer time, or Daylight Saving Time (DST) as is it is known in
some countries, calls for setting clocks ahead one hour during the
summer season. Note that the use of summer time depends on
the country and even the local area.

or off independently for each
World Time Mode city. Note,
however, that you cannot turn
on summer time for the “GMT”
city code.

DST Indicator
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).
• 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
setting as detailed under “Configuring
Home Time Settings”.
• Correctly configure the Home City
settings as detailed under “Configuring
Home Time Settings”.
Cannot configure signal reception settings.
Cause: • 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: • Select one of the above as the Home City
as detailed under “Configuring Home
Time Settings”.
• 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.
