Current Time Setting

This watch automatically adjusts its time setting in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.

• Before using the watch in the Continental United States, first use the procedure
under “Setting Up the Watch for Use in the Continental United States” to set the time
in accordance with a time calibration signal.

• Note that after you set your Home City (the city where you normally use the watch)
code, you must also turn on the watch’s time calibration signal receiver if you want to
enable auto time calibration. See “About Auto Receive” for more information.

• See “Setting the Time and Date Manually” for information about manual settings.

• Before using the watch in Japan, first specify your Home City, select the DST setting

you want to use, and then perform the procedure under “To perform manual time
calibration signal reception”.

Setting Up the Watch for Use in the Continental United States

You need to make the following three settings before using this watch in the
Continental United States. The following provides a general overview of the setting
procedure. For full details, see “Setting the Time and Date Manually” and “Time
Calibration Signal Reception”.

• Specify the city code for your Home City (the city where you will normally use the
watch).

• Select the auto summer time (DST) setting.

• Perform the manual time calibration signal receive operation to set the current time.

Time Calibration Signal Reception

This watch is designed to pick up a time calibration signal and update its time setting
in accordance with the signal. There are two different methods you can use to receive
the signal: Auto Receive and Manual Receive. With Auto Receive, the watch
automatically receives the calibration signal three times each day and makes
appropriate adjustments. With Manual Receive, you perform a specific button
operation to receive the calibration signal.
Before performing a signal receive operation, remove the watch from you wrist and
position it as shown in the illustrations below.

• If your watch has a resin band, pass the end of the band through the band loop and
place the watch on a stable surface.

Note

• If you are using the time calibration signal to set the time for this watch, be sure to
correctly set your Home City. Otherwise, there is the chance that the watch will not
set the correct time. See “Setting the Time and Date Manually” for details.

• Note that signal reception is possible only when the watch is within range of a time
calibration signal transmitter, and a city code that supports signal reception is
selected as the Home City code.

• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make .

• Auto receive is turned on when the watch is shipped from the factory.

• See the information under “Time Calibration Signal Reception” if you experience

problems with time calibration signal reception.

To perform manual time calibration signal reception

1. Place the watch on a stable surface so its top (12 o’clock side) is facing in the
general direction of the signal transmitter.

• Note that signal reception is poor if the watch is on its back or side.

Receive indicator

Note

• To interrupt a receive operation and return to the Timekeeping Mode, press A.

• If the receive operation is unsuccessful, the message ERROR! appears on the

display for about one or two minutes. After that, the watch returns to the
Timekeeping Mode.

• You can also change from the Last Signal or ERROR! screen to the normal

timekeeping screen by pressing A.

About the Receive Indicator

The receive indicator shows the strength of the calibration signal being received. For best
reception, be sure to keep the watch in a location where signal strength is strongest.

Weak

• Even in an area where signal strength is strong, it takes about 10 seconds for signal

reception to stabilize enough for the receive indicator to indicate signal strength.

• Use the receive indicator as a guide for checking signal strength and for finding the

best location for the watch during signal receive operations.

• The receive indicator remains on the display in all modes following reception of the

time calibration signal and calibration of the watch’s time setting. The receive
indicator does not appear if signal reception was unsuccessful or after manual
adjustment of the current time setting.

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM
and 6:00 AM each day (calibration times).

Note

• The auto receive operation is performed only if the watch is in the Timekeeping or

World Time Mode when one of the calibration times is reached.
It is not performed if a calibration time is reached while you are making settings
(while settings are flashing on the display), while an alarm is sounding, or while a
silent alert operation is being performed.

• Auto receipt of the calibration signal is designed to be performed early in the

morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.

• The receive indicator indicates that either the 2:00 AM, 4:00 AM, or 6:00 AM

calibration signal reception was successful. Note, however, that the receive indicator
is cleared from the display at 3:00 AM each day.

• If you do not see the receive indicator except for the above reason, it means there

was some problem with the calibration reception operation. Either perform reception
manually, or make sure the watch is set up properly to receive the time calibration
signal for the next automatic reception time.

• Though this watch is designed to receive both time data (hour, minutes, seconds)

and date data (year, month, day), certain signal conditions can limit reception to time
data only.

• The receive indicator (

receive both time and date data. It does not appear when only time data is received.
When time and date data is received: Receive indicator (
When time data only is received: Receive indicator (

• Normally, the signal reception date shown by the Last Signal screen is the date data

included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows date as kept in the Timekeeping Mode at the
time of signal reception.

• When auto receive is turned on, the watch receives the calibration signal for two to

six minutes each day when the Timekeeping Mode time reaches 2:00 AM, 4:00 AM
and 6:00 AM. Do not operate any of the watch’s buttons within six minutes prior to or
following the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the time kept in the

Timekeeping Mode. The receive operation will be performed whenever the display
shows 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the
Timekeeping Mode time is actually the correct time.

• When two or three receptions are successful, the watch uses the data of the last

reception for calibration. When only one reception is successful, the watch uses the
data of the successful reception.
