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

•Time calibration signal reception takes from one to seven minutes, but in some cases it can take as long as 13 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. 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.

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 one 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.

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.

•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.

Transmitter indicator

The watch has transmitter names along the bottom of the display. The transmitter indicator flashes during signal reception above the name of the transmitter from which the watch is currently receiving a signal. After signal reception is complete, the indicator will remain, without flashing, above the name of the transmitter from which the signal was received.

•The following shows the meaning of each of the transmitter names along the bottom of the display.

•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.

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

1.Enter the Receive 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 RC appears on the display.

•The transmitter indicator flashes above the name of the transmitter whose signal the watch is attempting to receive.

•Time calibration signal reception takes from one to seven 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 Cor if you do not perform any button operation for about two or three minutes.

•If the current reception fails but a previous reception was successful, the display shows the previous reception’s date and time, and the ERR indicator.

- : - - indicates that none of the reception operations were successful.

The watch will enter the Timekeeping Mode without changing the time setting if you press Cor if you do not perform any button operation for about two or three minutes.
