Troubleshooting

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 may sometimes 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?
Remember that auto receive is not performed unless OSA
(Osaka), TYO (Japan), LAX (Los Angeles),  DEN (Denver), CHI
(Chicago), or NYC (New York) is selected as the Home City. For
details, see “To configure Home City settings”.

Is auto receive turned off?
Use the procedure under “To turn auto receive on and off” 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, 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.

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 “To configure Home City settings” to change the summer
time setting to OFF or AUTO.

Time calibration signal reception is successful, but the current
time setting is wrong.

Is the correct city code selected for your Home City? For details
about setting the correct Home City, see “To configure Home City
settings”.

I can’t turn auto receive on and off

Remember that auto receive cannot be turned on and off unless
OSA (Osaka), TYO (Japan), LAX (Los Angeles),  DEN (Denver),
CHI (Chicago), or NYC (New York) is selected as the Home City.
For details about setting the correct Home City, see “To configure
Home City settings”.

The information that should appear in the tide graph and the Moon
graph depends on your location. Be sure to configure the required
settings (Home City and area) about your location before trying to
use these graphs.

Once you specify your current location, you do not need to
change it unless you move to another relatively faraway
location, or if you allow the watch’s rechargeable battery to
go dead (which clears the current settings).

The following are the watch’s factory default settings: Home
City: Tokyo (GMT Differential: +9.0); Area: SHIBAURA.

Using the Tide/Moon Graph

When 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 its 12 o’clock position facing in the
general direction of the transmitter.

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
it near a window, with its 12 o’clock position facing in the general
direction of the transmitter.

How can I view the last reception 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.
