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 from Fort Collins, Colorado (USA). Reception is possible within North America*.
*The term “North America” in this User’s Guide 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.
Important!
•Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You can also perform manual receive or you can set the time manually.
•If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.
• Auto Receive |
With auto receive, the watch picks up the time calibration signal automatically five |
times a day at midnight, 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 |
•The first thing you should do after purchasing this watch is to set your Home City, which is the city where you normally will use the watch. For more information, see “To set your Home City” below.
•When using the watch outside of the range of the transmitter in Fort Collins, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings.
