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

STD/DST Switching
STD/DST switching can be performed either automatically or manually, depending
on time calibration signal reception conditions in your area, the use of daylight saving
time in your area, etc.

To confi gure the watch to switch between STD and DST automatically in
accordance with a time calibration signal, see "To toggle the Home City time
between standard time and daylight saving time" (page E-51).
