To look up the sunrise and sunset times for a specific city code

Important!

•You do not need to perform this procedure to look up the sunrise and sunset times in your currently selected Home City.

•If you select a different city code to look up the sunrise and sunset times there, return to the city code of your Home City (your current location) when you are finished. Otherwise, the time shown in the Timekeeping Mode will not be correct.

•For information about the Home City setting, see “Configuring Home City Settings”.

1.In the Timekeeping Mode, hold down E until the currently selected city code starts to flash. This is the city code setting screen.

•Before the city code starts to flash, the message SET Hold will appear on the display. Keep E depressed until SET Hold disappears and the city code starts to flash.

2.Use A (East) and C (West) to select the city code whose sunrise and sunset times you want to view.

•For details about city codes, see the “City Code Table”.

3.Press E twice to exit the setting screen.

•Exiting the Stopwatch Mode while a split time is frozen on the display clears the split time and returns to elapsed time measurement.

Using the Countdown Timer

The countdown timer can be configured to start at a preset time, and sound an alarm when the end of the countdown is reached.

Checking the Current Time in a Different Time Zone

You can use the World Time Mode to view the current time in one of 31 time zones (48 cities) around the globe. The city that is currently selected in the World Time Mode is called the “World Time City”.

Countdown time (Hour, minutes, seconds)

To enter the Countdown Timer Mode

Use D to select the Countdown Timer Mode (TMR) as shown in “Selecting a Mode”.

•About one second after TMR appears on the display, the display will change to show the countdown time hours.

In the World Time Mode, use A (East) and C (West) to scroll through city codes.

To specify standard time or daylight saving time (DST) for a city

1.In the World Time Mode, use A (East) and C (West) to display the city code (time zone) whose Standard Time/Daylight Saving Time

setting you want to change.

2. Hold down E until DST Hold appears on the display and then disappears. Release E after DST Hold disappears.

• This toggles the city code you selected in step 1 between Daylight Saving Time (DST indicator displayed) and standard time (DST indicator not displayed).

Start Stop (Restart) (Stop) Reset

•Before starting a countdown timer operation, check to make sure that a countdown operation is not in progress (indicated by the seconds counting down). If it is, press A to stop it and then C to reset to the countdown start time.

To stop the alarm

Press any button.

Using the Alarm

•Using the World Time Mode to change the DST setting of the city code that is selected as your Home City also will change the Timekeeping Mode time DST setting.

•Note that you cannot switch between standard time/daylight saving time (DST) while UTC is selected as the World Time City.

•Note that the standard time/daylight saving time (DST) setting

affects only the currently selected time zone. Other time zones are not affected.

Current time

You can set five independent daily alarms. When an alarm is turned on, an alarm will sound for about 10 seconds each day when the time in the Timekeeping Mode reaches the preset alarm time. This is true even if the watch is not in the Timekeeping Mode.

You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the hour.

To enter the Alarm Mode

Use D to select the Alarm Mode (ALM) as shown in “Selecting a Mode”.

•About one second after ALM appears on the display, the display will change to show an alarm number (AL1 through AL5) or the SIG indicator. The alarm number indicates an alarm screen. SIG is shown when the Hourly Time Signal screen is on the display.

•When you enter the Alarm Mode, the data you were viewing when you last exited the mode appears first.
