duration and 12/24-hour format, to toggle power saving on and off, and to show or

only (no date or day of the week). You can change the configuration of the watch so
the main timekeeping screen also displays the date or day of the week. For details
about how to do this, see "Displaying the Date or Day of the Week".

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 signal transmitted from Fort Collins includes 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 received
time signal.
• The default DST setting is Auto DST (AT) whenever you select YVR, LAX,
YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, or YYT as your
Home City code.
• If you experience problems receiving the time calibration signal in your area, it
probably is 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 A until the city code starts to flash, which
indicates the setting screen.
2. Press B and the DST setting screen appears.
3. Use C to cycle through the DST settings in the sequence shown below.

the main timekeeping screen also displays the date or day of the week.
You can select either the date or the day of the week for display along with the current
time on the main timekeeping screen.
