Troubleshooting

Signal Reception (Time Calibration Signal)

Q1‏The watch cannot perform a receive operation.

Is the watch’s battery charged?

Signal reception is not possible while battery power is low. Keep the watch exposed to light until it recharges sufficiently.

Is the watch in the Timekeeping Mode or World Time Mode?

Time signal receive is not possible unless the watch is in the Timekeeping Mode or World Time Mode. Enter the Timekeeping Mode or World Time Mode.

Is your Home City setting correct for your location?

The watch will not indicate the correct time if the Home City setting is wrong. Change your Home City setting so it correctly reflects your location.

After checking the above, the watch still cannot perform a receive operation.

Time calibration signal reception is not possible under the conditions described below.

If successful reception is not possible for some reason, you can adjust the time and day settings manually.

Q2‏The signal receive operation always fails.

Is the watch in a location that is appropriate for signal reception?

Check your surroundings and move the watch to a location where signal reception is better.

Did you avoid touching the watch while the receive operation was in progress?

Minimize movement of the watch and do not perform any watch operation while a receive operation is in progress.

Is there an alarm configured to sound during the same period that the signal receive operation is performed?

Receive stops if an alarm operation starts while it is being performed. Disable the alarm.

Is the signal transmitter in your area transmitting a signal?

The transmitter of the time calibration may not be transmitting a signal.
Try again later.

Q3‏Signal reception should have been successful, but the watch’s time and/or day is wrong.

Adjust time and day settings manually.

World Time

Q1‏The time for a World Time City is not correct.

The summer time setting (standard time/summer time) is wrong.

Alarm

Q1‏The alarm does not sound.

Is the alarm setting turned on? If it isn’t, turn it on so it will sound.

Charging

Q1‏The watch does not work even though it is exposed to light.

The watch stops operating whenever the battery goes dead. Keep the watch exposed to light until it recharges sufficiently.

Q2‏[H], [M], and [L] are flashing on the display.

The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.

If a signal receive operation, alarm, hourly time signal, illumination and/or other power-intensive functions are used within a short period of time, the charge level of the battery will drop and cause the watch to go into a charge recovery mode. Function availability will be temporarily limited, but functionality will return after the battery recovers.
