Troubleshooting

Cannot perform manual reception.
Possible Cause:

The watch is not in the Timekeeping Mode

or World Time Mode.

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 reception while a time

screen is on the display in the Timekeeping

Mode or World Time Mode only.

Change Home City To TYO (Tokyo), NYC

(New York), CHI (Chicago), DEN

(Denver), or LAX (Los Angeles).

The

icon is not displayed even though auto reception is

turned on.
Possible Cause:

A single receive operation was not

successful.

Both the hour-minute-second group and

year-month-day group were not received.

The watch is not in the Timekeeping Mode

or World Time Mode when an auto

reception time is reached.

You performed manual reception, which

clears the icon from the display.

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.

The icon disappears from the display

whenever you change the current time

setting manually.

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 receive operation. Remember

that geographic contours, nearby buildings, the season, and the

time of day can 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 signals 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 calendar shows dates up to the year 2099.

Attempting a receive operation after that causes an error.

If only the hour-minute-second group is received, the Timekeeping

Mode date at the time of reception is recorded as the last

reception date.
