• Is the watch in any mode other than the Timekeeping Mode or
World Time Mode during the auto receive times (midnight, 1:00
a.m., 2:00 a.m., 3:00 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.
2. 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 off slightly (within one
second).
3. 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 “To configure Home City settings” to
change the summer time setting to OFF or AUTO.
4. Time calibration signal reception is successful, but the
current time setting is wrong.
• Is TYO (Tokyo) selected for your Home City?
For details about setting the correct Home City, see “To configure
Home City settings”.
Troubleshooting
1. The watch cannot receive the time calibration signal.
• 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 sometimes may be interrupted for periodic
maintenance work, or because of lightning or other problems.
• Are you within the reception range of a transmitter?
See “Reception Ranges” 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 (see “Location”) during signal
reception.
• Do you have the correct Home City code selected?
Calibration signal reception will be impossible if you have any city
that is not included under “Reception Ranges” selected as your
Home City. For details about setting the correct Home City, see
“To configure Home City settings”.
• Is auto receive turned off?
Use the procedure under “To turn auto receive on or off” to turn on
auto receive.

World Time
• Pressing the A button in the World Time Mode displays the city
code of the currently selected city for about two seconds.
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 synchronized 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.
• See “To configure Home City settings” for more information.

5. The digital time and analog time are different.
• Normally, received time calibration data is used to adjust the
digital display time, and then the analog hands are adjusted to
match the digital time.
If the hands are misaligned for some reason, they will not indicate
the correct time. If this happens, use the procedure under
“Configuring Analog Settings” to adjust the analog time.
6. I can’t turn auto receive on and off
• You will not be able to turn auto receive on or off if you have any
city that is not included under “Reception Ranges” selected as
your Home City. For details about setting the correct Home City,
see “To configure Home City settings”.
7. What time is auto receive performed?
• Auto receive is performed in the middle of the night, when
reception conditions are best. Before going to bed at night, place
the watch near a window, with 12 o’clock facing in the general
direction of the transmitter.
8. How can I perform manual receive?
• Hold down the lower right D button for about two seconds. The
watch will beep to indicate that manual receive has started. Place
the watch near a window, with 12 o’clock facing in the general
direction of the transmitter.
9. How can I view the last receive operation date and time?
• In the Timekeeping Mode, press the lower right D button. This
will display the date and time that the time calibration signal was
last received successfully. To return to the Timekeeping Mode,
press the D button again.
• 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.
