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 Strong

•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.

To trigger a calibration signal receive operation manually

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 ) indicator on the watch’s display should scroll from left to right, which indicates that signal reception has started.

•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.

To toggle between the Timekeeping and Last Signal screens

In the Timekeeping Mode, press C to toggle between the Timekeeping screen and the Last Signal screen.

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 ( ) indicates that one, two, or all three of the last calibration 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.
