TIMEKEEPING
This watch automatically adjusts its time setting in accordance with the time
calibration signal (Call Sign: WWVB) transmitted from the National Institute of
Standard and Technology (NIST) in Fort Collins, Colorado. You can also perform a
manual procedure to set the time and date, when necessary.
Important!
• Before using the watch after purchasing it, use the procedure under “Selecting Your
Time Zone City Code” to specify your city code, and then use the procedure under
“To trigger a calibration signal receive operation manually”.
• The Fort Collins time calibration signal includes both standard time and Daylight
Saving Time data. This means the watch can automatically adjusts for DST, even if
you do not specify it manually. See “Daylight Saving Time Setting” for more
information.
Setting the Time and Date
There are three different methods you can use to set the watch’s time and date.
• Auto receive of the time calibration signal
• Manual receive of the time calibration signal
• Manual setting without using the time calibration signal
No matter which method you use, you must specify your time zone city code first (see
below).
Selecting Your Time Zone City Code
Use one of the procedures below to specify your current time zone. If you move to a
different time zone either inside or outside of the Continental United States, simply
change the time zone setting and the watch adjusts its current time and date settings
accordingly.
• To select a time zone within the Continental United States, use the procedure under
“To select your time zone city code”.
• To select another time zone, use the procedure under “To select a time zone outside
the Continental United States”.
Important!
• Make sure you set the correct time zone city code for the time zone where you are
located. The wrong time zone city will cause the watch to display the wrong time.
• The time zone city code (LAX, DEN, CHI, NYC, etc.) is not shown on the
Timekeeping screen. See “To view the current time zone city code”.
To select your time zone city code
In the Timekeeping Mode, use the key operations shown in the table below to select
the indicated city code. Hold down this key until the watch beeps (about two seconds).
• Selecting a city code causes the year, month, day, hour, minutes, and DST settings
to change accordingly.

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.
Recieve indicator
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.

Current time
• Time calibration signal reception takes from four to 11 minutes. Take care that you
do not move the watch during this time.
• To interrupt a receive operation and return to the Timekeeping screen, press A.
• When a receive operation is successful, the receive date and time change, and
the receive indicator appears on the Last Signal screen.
Note
• If the receive operation is unsuccessful, the message “ERR” appears on the Last
Signal screen for about one or two minutes. After that, the watch returns to the
Timekeeping screen.
Last Signal Screen
The Last Signal Screen appears after the watch attempts a calibration receive
operation. The Last Signal screen shows the date and time of the last receive
operation if it was successful, or an error message if the receive operation failed. You
can also display the Last Signal screen at any time using the button operation
described below.

About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the Timekeeping Mode reaches a calibration time (0:00 AM,
2:00 AM, and 4:00 AM) each day.
Note
• The Auto Receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if the calibration time is reached while you are making settings (while
settings are flashing on the display), while an alarm is sounding or while you are
performing a key operation.
• Auto receive is performed at 0:00 AM, 2:00 AM, and 4:00 AM, 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 (
time reception attempts were successful. The receive indicator disappears from the
display when the Timekeeping Mode reaches midnight or when you perform a
manual receive operation.
• When auto receive is turned on, the watch receives the calibration signal for four to
11 minutes each day when the Timekeeping Mode time reaches 0:00 AM, 2:00 AM,
and 4:00 AM. Do not operate any of the watch’s buttons within 15 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 Timekeeping
Mode time. The receive operation will be performed whenever the Timekeeping
Mode time is 0:00 AM, 2:00 AM, and 4:00 AM, regardless of whether or not the
displayed 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.
Timekeeping Last Signal
1. Place the watch on a stable surface so its top (12
o’clock side) is facing in the general direction of Fort
Collins, Colorado.
• This puts the watch in the optimum position for time
calibration signal reception.
2. In the Timekeeping Mode, hold down C for about two
seconds, until the watch beeps.
• At this time, the (

Setting the Time and Date Manually
The times displayed in the Timekeeping Mode and World Time Mode are linked. Even
if you plan to use the watch without enabling auto time calibration, be sure to select a
time zone city code (the time zone whose time and date you are setting), before you
set the time and date. When you move to another time zone, you can adjust watch’s
time by simply selecting the new time zone.
Note
If the receive indicator is on the display, manually changing the date, time, DST, or
time zone setting causes it to disappear.

Daylight Saving Time (DST)
Daylight Saving Time automatically advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use
Daylight Saving Time.
Daylight Saving Time Setting
The time calibration signal sent from Fort Collins includes Standard Time and Daylight
Saving Time information. Selecting DST AUTO for the DST setting after you select the
city code for your current time zone, you do not need to make any adjustments to
switch between Standard Time and Daylight Saving Time while you are in a U.S. area
where Daylight Saving Time is followed. The initial factory default setting for the DST
setting is DST AUTO .
• Make sure you change the DST setting to DST OFF when you are in a U.S. area
that does not follow DST.
• You need to set the DST setting whenever the time zone of the city code you have
selected is outside the Continental United States.
To change the Daylight Saving Time setting
Important!
Note that the DST AUTO option is available while the time zone city code setting is
LAX, DEN, CHI, or NYC only. For other time zones, you can select DST ON or DST
OFF only.
