	indicator									• Supported time calibration signals: United States (Fort
										Collins), England (Rugby).
										Current Time Setting
										This watch adjusts its time setting automatically in
										accordance with a time calibration signal. You can also

	(Hour : Minutes Seconds)
										“To specify your Home City”.

•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 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.

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: HNL (Honolulu), ANC (Anchorage), ATH (Athens), and MOW (Moscow). 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.

•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 (summertime), turn off the DST setting.

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. When any auto receive is successful, the remaining auto receive

operations are not performed. 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”.

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.

•Make sure the watch is facing the right way.

•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 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.

•The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

Home City Codes and Transmitters

	Home City Code	Transmitter	Frequency

*The areas covered by the HNL, ANC, ATH, and MOW city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.

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

Rugby (England) transmitter: 500 kilometers (310 miles)

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

•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” if you experience problems with time calibration signal reception.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day. 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.

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 receive 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.

•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. Avoid performing 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 in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

•Calibration signal reception is disabled while a countdown timer operation is in progress.

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.

Weak	Strong
(Level 0)	(Level 3)

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.

•Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 3 receiving indicator will remain on the display in all modes. The Level 3 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

•The Level 3 receiving indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.

•The Level 3 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared from the display when the first auto receive operation of the day is performed.

To perform manual receive

1. Place the watch on a stable surface so its top (12 o’clock side) is facing towards a window.

2. In the Timekeeping Mode, hold down Dfor about two

seconds until RC! appears on the display.

• Time calibration signal reception takes from two to

seven minutes. Take care that you do not perform any button operations or move the watch during this time.

• After signal reception is complete, the display of the watch changes to the Last Signal screen.

Note

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

•If the receive operation is unsuccessful, the message ERR appears on the display for about one or two minutes. After that, the watch returns to the Timekeeping Mode.

•You can also change from the Last Signal or ERR screen to the normal timekeeping screen by pressing D.

•Calibration signal reception is disabled while a countdown timer operation is in progress.
