Operation Guide 5015
*The areas covered by the MOW, HKG, BJS, HNL, and ANC city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.

1.Enter the Timekeeping Mode.
2.Place the watch on a stable surface so its 12 o’clock
side is facing towards a window.
3. Hold down Dfor about two seconds until the Receiving Indicator appears on the display.
•Time calibration signal reception takes from two to 14
minutes. Take care that you do not perform any button operations or move the watch during this time.
•If the receive operation is successful, the reception date and time appear on the display, along with the GET indicator.
The watch will enter the Timekeeping Mode if you press Dor if you do not perform any button operation for about one or two minutes.
•If the current reception fails, the display will show the ERR indicator.
The watch will enter the Timekeeping Mode without changing the time setting if you press Dor if you do not perform any button operation for about one or two minutes.
•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.
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)
•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.
•The display of the watch is blank while an auto receive operation is in progress.

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 every day 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.

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