Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.
•This watch is designed to pick up the time calibration signal transmitted in the United States (Fort Collins, Colorado) and the time calibration signals transmitted in Japan.
•The U.S. time calibration signal can be picked up by the watch while in North America*.
*The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.
•The first thing you should do after purchasing this watch is to specify your Home Time Zone, which is the time zone where you will normally use the watch. For more information, see “To specify your Home Time Zone” below.
•When using the watch outside the range of the time signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
