•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.

•As of March 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly.

•Using this watch in a country covered by a time calibration that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

To specify your Home City

1.In the Timekeeping Mode, hold down A for about three seconds. You can release the button after “ADJ” appears on the display.

•At this time, “12H” (12-hour timekeeping) or “24H” (24- hour timekeeping) also will be flashing on the display.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

•This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can 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” (page E-12).

•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” (page E-53) for more information about manual time settings.

•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 also can perform manual receive (page E-25) or you can set the time manually (page E-54).

•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 page E-18 and “Transmitters” (page E-72).

•See the maps under “Approximate Reception Ranges” (page E-19) for information about the reception ranges of the watch.

•You can disable time signal reception, if you want. See “To turn auto receive on and off” on page E-27 for more information.

•Under factory default settings, auto receive is turned off for all of the following city codes: HNL (Honolulu) and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off” on page E-27.

E-14

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 receives the time calibration signal automatically up to 6 times a day (5 times a day for the Chinese calibration signal). When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive” (page E-22).

•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” (page E-25).

E-15

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 pointing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

•Proper signal reception can be difficult or even impossible under the conditions listed below.

•Signal reception normally is better at night than during the day.

•Time calibration signal reception takes from three to eight minutes, but in some cases it can take as long as 16 minutes. Take care that you do not perform any button operations or move the watch during this time.
