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 calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
Troubleshooting
The watch cannot receive the time calibration signal.
•
Is the signal being transmitted?
Though the Japanese calibration signal (Call Sign: JJY) is
continually transmitted by the independent Japan Ministry of
Posts and Telecommunications Communication Research
Laboratory (CRL) in theory, it may sometimes be interrupted for
periodic maintenance work, or because of lightening or other
problems.
•
Are you within the reception range of a transmitter?
See “Reception Range” for information about areas where the
watch can receive the 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” for more information.
•
Do you have the correct Home City code selected?
Remember that auto receive is not performed unless TYO
(Japan), 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 auto receive turned off?
Use the procedure under “Configuring Auto Receive Settings” to
turn on auto receive.
•
Is the watch in any mode other than the Timekeeping Mode or
World Time Mode during the auto receive times (midnight, 2:00
a.m., 4:00 a.m., and 5:00 a.m.)?
Auto receive is performed only when the watch is in the
Timekeeping Mode or World Time Mode. It is not performed if the
watch is in any other mode.
Time calibration signal reception is successful, but the hourly
time signal and current time are slightly off.
•
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 slightly off (within one
second).
Time calibration signal reception is successful, but the current
time is one hour fast.
•
Do you have summer time (DST) turned on?
Use the procedure under “Configuring Summer Time (Daylight
Saving Time) Settings” to turn off summer time.
Time calibration signal reception is successful, but the current
time setting is wrong.
•
Is the correct city code selected for your Home City?
If you are in Japan, you should have TYO selected for your Home
City. For other areas, select the correct Home City code using the
procedure under “Selecting Your Home City”.
