•For information about selecting a Home City, see “To manually set the time and date”.

•The initial factory default settings of the watch are TYO (Tokyo) for the Home City and FREQ. AT (auto select) for the transmitter mode.

Calibration Signal Reception Precautions

•Auto reception can be performed while the watch is in the Timekeeping Mode or World Time Mode only.

•Operating any button while auto reception is in progress will cause the watch to beep and then exit the receive operation.

•Make sure you are within the range of the calibration signal transmitter before performing the reception operation. Remember that geographic contours, nearby buildings, the season, the time of day, can even make reception impossible even when you are within range of the transmitter.

•Proper reception may be impossible if there is something blocking the signal. If reception is unsuccessful, try again.

•This watch is designed to adjust its current time setting in accordance with the calibration signal transmitted in Japan and the United States only. Note that you will need to make your own adjustments when using this watch outside of Japan or the United States, or in any area that is outside the range of one of the receivable time calibration signal transmitters.

•When the watch is unable to adjust its time signal using the calibration signal for some reason, timekeeping accuracy is within

±15 seconds per month.

•Strong electrostatic charge can cause timekeeping error.

•Signal reception is cancelled if an alarm starts to sound while it is being performed.

•The watch's built-in calendar runs up to the year 2039. Signal reception after that causes an error, and the date remains displayed as December 31, 2039.

Troubleshooting

Cannot perform manual reception.

Cause:• Manual receive can be performed in the Timekeeping Mode only.

•The Home City is set to a city other than TYO (Tokyo), NYC (New York), CHI

(Chicago), DEN (Denver), or LAX (Los Angeles).

Corrective Measures: • Perform manual receive in the Timekeeping Mode.

•Change Home City to TYO (Tokyo), NYC (New York), CHI (Chicago), DEN (Denver), or LAX (Los Angeles). For details, see “To manually set the time and date”.

The “ ” icon is not on the display even though auto signal reception is turned on.

Cause:• The “ ” icon appears after the watch successfully receives the calibration signal and adjusts the current time and date settings.

•A single receive operation was not successful.

•The “ ” icon is displayed only when both the hour-minute-second group and year- month-day group were received. It will not remain on the display if only the hour- minute-second group is received.

•The watch is not in the Timekeeping Mode or World Time Mode when an auto

reception time is reached.

Corrective Measures: • Check to make sure the watch is in a location where it can receive the signal.

•Place the watch in a location where reception conditions are good.

•Make sure that the watch is in the Timekeeping Mode or World Time Mode during the auto reception times.

•Note that manual reception also clears the “ ” icon from the display.

Time setting is incorrect following signal reception.

Cause:• Summer time is turned on or the wrong Home City is selected.

Corrective Measures: • If the time is advanced by one hour, it probably means that summer time (indicated by the DST indicator on the display) is turned on. If the time is off by more than one hour, it probably means that the Home City is selected. Correctly configure the summer time and Home City settings as detailed under “To manually set the time and date”.

If you cannot receive the calibration signal or if the current time setting is incorrect after signal reception, check the current setup of the watch.

•The following are the watch’s factory default settings, which are configured automatically whenever you have the battery of the watch replaced.
