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 automatically adjusts its digital time setting 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 U.S. and Japanese time signal transmitters, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
•The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is adjusted automatically whenever you change the digital setting. See “Analog Timekeeping” for more information.

Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal: auto receive and manual receive. The second hand stops at the 12 o’clock position while time calibration signal reception is in progress. After reception is complete, the second hand moves automatically until it matches the digital time.
•Auto Receive
With auto receive, the watch automatically picks up the time calibration signal five times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.
•Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.
