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 –5.0, –6.0, –7.0, –8.0, –9.0, –10.0, +8.0, or +9.0 ( –4.0, –5.0, –6.0, –7.0, –8.0, –9.0, +9.0, or +10.0 while DST is turned on) 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.In the Timekeeping Mode, hold down Auntil the GMT differential value starts to flash, which indicates the setting screen.

2.Press Cto display the DST setting screen.3.Press Bto cycle through the DST settings in the sequence shown below.
