Radio-controlled Atomic Timekeeping

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 in the United States (Fort Collins, Colorado) and the time calibration signals transmitted in Japan.

• 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.

Current Time Setting

This watch automatically adjusts its digital time setting 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 Time Zone, which is the time zone where you will normally use the watch. For more information, see “To specify your Home Time Zone” below.

• When using the watch outside the range of the U.S. and Japanese time signal transmitters, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

• The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is adjusted automatically whenever you change the digital setting. See “Analog Timekeeping” for more information.

To specify your Home Time Zone

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

• Selecting –5.0, –6.0, –7.0, –8.0, or +9.0 as your Home Time Zone automatically turns on auto receive. When auto receive is turned on and you are within the reception range, the watch will automatically receive the time calibration signal from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between time zones (GMT differential values) and transmitters, see “Transmitters”.

• See the maps under “Reception Ranges” for information about the reception ranges of the watch.

• If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.

• If W60, A, J40, J60, or OFF starts to flash in place of the GMT differential value when you hold down A in step 1 of the above procedure, press A again to exit the setting screen. After that, press B and then perform step 1 again.

To display the digital time and last signal screen

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal:

auto receive

and while time calibration signal reception is in progress. After reception is complete, the second hand moves automatically until it matches the digital time.

• Auto Receive

With auto receive, the watch automatically picks up the time calibration signal five times a day at 0:00 a.m., 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

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

• The watch should not be on its side or facing the wrong way.

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

below.

Inside or among buildings

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

• Time calibration signal reception takes from two to seven minutes, but in some

cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• When within range of the applicable transmitter, this watch can receive either the U.S. (Fort Collins, Colorado) or Japanese (Fukushima or Fukuoka/Saga) time calibration signals. See “Transmitters” for more information.

• Under good reception conditions, signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.

• At distances further than about 600 miles (1,000 kilometers) from the Fort Collins transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

• At distances further than about 500 kilometers from the Fukushima and Fukuoka/ Saga transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

• See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the digital time in the Timekeeping Mode reaches 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive operation at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.

Note

• Auto receive turns on automatically whenever you select –5.0, –6.0, –7.0, –8.0, or +9.0 as your Home Time Zone. For information about turning off auto receive, see

“To select the transmitter mode”.

• The auto receive operation is performed only if the watch is in the Timekeeping Mode or Dual Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display).

• 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 easily receive the signal.

• When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the current time on the digital display. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time is actually the correct time.

• When two, three, four, or five receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.

About the Receiving Indicator

The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest.

Receiving indicator

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

• The Level 4 receiving indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.

• The Level 4 receiving indicator indicates that at least one of the calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 3:00 a.m. each day.

To perform manual receive

Receiving indicator

• Time calibration signal reception takes from two to seven minutes. In Japan, however, reception can take up to 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• After signal reception is complete, the watch beeps and the display of the watch changes to the last signal screen.

Note

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

• If the receive operation is unsuccessful, – – – – – – appears on the display for about

one or two minutes. After that, the watch returns to the Timekeeping Mode.
