Radio-controlled Atomic Timekeeping

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

•Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United States (Fort Collins), China (Shangqiu), and Japan (Fukushima or Fukuoka/Saga)

•See the information under “Signal Reception Troubleshooting” (page E-29) if you experience problems with time calibration signal reception.

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, which is the city where you normally will use the watch. For more information, see “To specify your Home City” on 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 “Configuring Time and Date Settings Manually” (page E-41) for more information about manual time settings.

To specify your Home City

• Normally, your watch should show the correct time as soon as you specify your

City code

Second hand

1.In the Timekeeping Mode, keep A depressed (for about five seconds) as the second hand moves to the last signal reception result (“Y” or “N”), then to “READY” (or “R” for some models), and then to the city code of the currently selected Home City.

•This indicates the city code setting mode.

2.Use D to move the second hand clockwise to the city code you want to use as your Home City.

•For information about the Home City, see “Home City Codes and Transmitters” (page E-13). The watch will receive the time calibration signal of the transmitter of the selected city code.

3.After the Home City setting is the way you want, press A to return to the Timekeeping Mode.

Home City code. If it does not, it should adjust automatically after the next auto

receive operation. You also can perform manual receive (page E-26) or you can set

the time manually (page E-41).

• Even if the time calibration signal is received correctly, there are some times when

the analog hands may not indicate the correct time. If this happens, use the

procedures under “Auto Hand Home Position Correction” (page E-45) to check the

home positions of the hands, and make adjustments as required.

Home City Codes and Transmitters

• The time calibration signal the watch will attempt to pick up depends on its current

Home City code setting as shown below. If you use the watch in Japan or Europe

(each of which has two different transmitter locations), it will try to receive the time

calibration signal from one of the transmitters in your current location. If it cannot

receive the signal, it will then try to receive the time calibration signal from the other

transmitter.

Approximate Reception Ranges

 

E-13

•City codes in parentheses indicate areas where reception may be possible only when conditions are good.

•For full information on city codes, see the “City Code Table” at the back of this manual.

•In addition to the above, you also can select city codes that are outside the ranges of the time calibration signal transmitters supported by this watch.

•Note that this watch does not have a city code that corresponds to Newfoundland.

•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 December 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.

•Signal reception may not be possible up to the distances noted below during certain times of the year or day. Radio interference may also cause problems with reception.

Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)

Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)

Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

Shangqiu (China) transmitter: 500 kilometers (310 miles)

•Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.

•Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

•See the information under “Signal Reception Troubleshooting” (page E-29) if you experience problems with time calibration signal reception.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

•The watch will adjust the DST setting automatically when it receives a time calibration signal while any one of the following city codes is selected as the Home City.

LON, PAR, ATH, TYO, ANC, LAX, DEN, CHI, NYC

•The watch will not adjust the DST setting automatically while either of following city codes is selected as the Home City. In this case, you will need to change between standard time and daylight saving time manually.

HKG, HNL

•For information about the DST setting, see “To set your Home City time” (page E-38).

•As of June 2008, 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.
