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 Western Europe, first use the procedure under "Setting Up
the Watch for Use in Western Europe" 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.
Setting Up the Watch for Use in Western Europe
You need to make the following three settings before using this watch in Western

watch).
• Select the auto summer time (DST) setting.

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 your 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 BER, PAR, LON, or ATH is selected as the Home
City code.
• See "City Code Table" for a complete list of available city codes.
• 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.
2. In the Timekeeping Mode, hold down A for about two
seconds until the watch beeps.
• Release A and the message receiving appears to
indicate that signal reception has started.
• Time calibration signal reception takes from two to six
minutes. Take care that you do not move the watch
during this time.
• After signal reception is complete, the display of the
watch changes to the Last Signal screen.
• The receive indicator indicates that the calibration time
reception attempt was successful.
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.
• 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.
