Alarm Operation

The alarm tone sounds at the preset time for 10 seconds, regardless of the mode the watch is in. In the case of the snooze alarm, the alarm operation is performed a total of seven times, every five minutes, or until you turn the alarm off.

The target alarm counts the time remaining from the current time in your Home Time Zone until the target alarm time. Note that the target alarm repeats automatically each day, as long as it is turned on. You need to turn off the target alarm to disable it.

•Alarm and Hourly Time Signal operations are performed in accordance with the Timekeeping Mode digital time.

•Pressing any button stops the alarm tone operation.

•Performing any one of the following operations during a 5-minute interval between snooze alarms cancels the current snooze alarm operation.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

The time calibration signals include both Standard Time and DST data. When the auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signal it receives.

•The auto DST setting can be turned on only while +0.0, +1.0 or +2.0 is selected as the Home Time Zone.

•If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer time) manually.

To change the Daylight Saving Time (summer time) setting

1.While any screen other than the last signal screen is on the display in the Timekeeping Mode, hold down A until the GMT differential value starts to flash, which indicates the setting screen.

2.Press Cto display the DST setting screen.

3.Press Dto cycle through the DST settings in the sequence shown below.

Analog Timekeeping

The analog time of this watch is synchronized with the digital time. The analog time setting is adjusted automatically whenever you change the digital time.

Note

•The hands for the analog timepiece move to adjust to a new setting whenever any of the following occurs.
