This watch receives a time calibration signal and updates its time setting accordingly.
•Supported time calibration signals: Germany (Mainflingen), England (Rugby), United States (Fort Collins), Japan.
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 City (the city where you normally will use the watch). For more information, see “To specify your Home City” below.
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. |
• The watch will receive the time calibration signal automatically from the applicable |
transmitter (in the middle of the night) and update its settings accordingly. For |
information about the relationship between city codes and transmitters, see “Home |
City Codes and Transmitters”. |
• Under factory default settings, auto receive is turned off for all of the following city |
codes: MOW (Moscow), HKG (Hong Kong), BJS (Beijing), HNL (Honolulu), and |
ANC (Anchorage). For details about turning on auto receive for these city codes, see |
“To turn auto receive on and off”. |
• You can disable time signal reception, if you want. See “To turn auto receive on and |
off” for more information. |
•When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
•The Timekeeping Mode can be used to display the current time and date in your Home City, or the current time in your Home City (Home Time) and in one more time zone (Zone 2 Time). You can even specify a city code that supports time calibration signal reception as the Dual Time Zone 2 city code. For details about Dual Time, see “Timekeeping”.
•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.

•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”.
Important!
•When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o'clock side facing towards a window. Make sure there are no metal objects nearby.
