Troubleshooting
1. The watch cannot receive the time calibration signal.
•
Is there something in the immediate area that may be interfering
with reception?
Even if you are within the reception range of a transmitter, objects
between you and the transmitter or electrical noise can interfere
with reception. Avoid such areas during signal reception. See
“Location”.
•
Are you within the reception range of a transmitter?
See “Reception Ranges” for information about areas where the
watch can receive the signal.
•
Do you have the correct Home City code selected?
Remember that auto receive is not performed unless
TYO
(Tokyo),
HKG
(Hong Kong),
NYC
(New York),
CHI
(Chicago),
DEN
(Denver), or
LAX
(Los Angeles) is selected as the Home
City. Select the correct Home City code using the procedure
under “Selecting Your Home City”.
•
Is the signal being transmitted?
Though the time data of the Japanese calibration signal (Call
Sign: JJY) is maintained by the Japan Standard Time Group of
the National Institute of Information and Communications
Technology (NICT), it may be interrupted sometimes for periodic
maintenance work, or because of lightning or other problems.
Calibration Signal Reception
Precautions
•
Auto receive is disabled while the watch is in the Chronograph
Mode.
•
Operating any button while auto receive 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 that
noted in the specifications at the back of this manual.
•
Strong electrostatic charge can cause timekeeping error.
•
Signal reception is cancelled if an alert operation starts 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 you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup
of the watch.

2. Time calibration signal reception is successful, but the
hourly time signal and current time are off slightly.
•
After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting.
Because of this, the time setting may be off slightly (within one
second).
3. Time calibration signal reception is successful, but the
current time setting is wrong.
•
Is
TYO
(Tokyo) or
HKG
(Hong Kong) selected for your Home
City?
Select the correct Home City code using the procedure under
“Selecting Your Home City”.
4. Cannot configure signal reception settings.
•
Remember that auto receive is not performed unless
TYO
(Tokyo),
HKG
(Hong Kong),
NYC
(New York),
CHI
(Chicago),
DEN
(Denver), or
LAX
(Los Angeles) is selected as the Home
City. Select the correct Home City code using the procedure
under “Selecting Your Home City”.

stop an elapsed time measurement operation.
•
Pressing the

operation is in progress resets the chronograph to zero.
Cumulative Time Measurement
Pressing the
B
button to restart the chronograph without resetting
it to all zeros resumes elapsed time measurement from where it
was last stopped.
Using the
Chronograph
The chronograph performs 1/20-second elapsed time measurement
up to 23 hours, 59 minutes, 59.95 seconds (24 hours). When the
maximum limit is reached, the elapsed time returns to zero
automatically and timing continues from there.
