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 Time and Date Settings Manually” (page E-41) for more information about manual time settings.

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

• 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.

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.

•

If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually. For more information, see “Home City and DST” (page E-38).

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 six times a day (five times for the China signal). When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive” (page E-23).

• 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-26).

E-20

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. 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.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day (five times for the China signal). When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City.

E-23

Note

• When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

• Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

• Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode.

E-25

• If reception is successful, the second hand will move to

YES (Y), and the date and time settings will be adjusted accordingly. Normal timekeeping will resume after that.

YES (Y)

Note

• To interrupt a receive operation and return to the Timekeeping Mode, press any button.

• If reception is not successful, the second hand will move to NO (N). Five seconds later, the second hand will resume normal operation, without any adjustment of the hand setting.

•

If the second hand is pointing to Mode by pressing

NO (N)

YES(Y

) or NO(N), you can return to the Timekeeping

Viewing the Latest Signal Reception Results

You can use the procedure below to check whether or not the last signal receive operation was successful.

To check the latest signal reception results

NO (N)

E-28

In the Timekeeping Mode, press A.

• If the watch was able to perform a successful signal receive operation since midnight, the second hand will move to YES (Y). If the watch has been unable to receive any signal successfully, the second hand will

move to NO (N).

• The watch will return to the Timekeeping Mode after five seconds or when you press A.

• The current receive result is cleared when the first auto receive operation is performed on the following day. This means YES (Y) indicates successful signal reception since the start of the current day.

YES (Y)

• If you adjust the time or date setting manually, the second hand will move to NO (N).

Signal Reception Troubleshooting

Check the following points whenever you experience problems with signal reception.

Problem

The second hand is pointing at NO (N).

Probable Cause

• You changed the time setting manually.

• You performed some button operation during the auto receive operation.

• The watch is not in the Timekeeping Mode.

• Signal reception results are reset when the first auto receive operation is performed on the following day.

• Radio interference is often present during the day time, which can interfere with calibration signal reception.

What you should do

Perform manual signal

•

receive at night or wait until the next auto signal receive operation is performed.

•

Enter the Timekeeping Mode and try again.

• Check to make sure the watch is in a location where it can receive the signal (page E-21).
