If the receive operation is unsuccessful, the message “ERR” appears on the Last Signal screen for about one or two minutes. After that, the watch returns to the Timekeeping screen.

You can also change from the Last Signal screen to the Timekeeping screen by pressing D.

About the Receive Indicator

The receive 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.

Remaining time (Hours : Minutes Seconds)

You can set three independent Daily Alarms, and even input text that appears on the display to remind you of the purpose of each alarm. When an alarm is turned on, the alarm tone sounds when the alarm time is reached. You can also turn on an Hourly Time Signal that causes the watch to beep twice every hour on the hour.

The remaining time shows the amount of time from the current time (Timekeeping Mode time) until the alarm time whose screen is on the display.

The alarm number (“AL1” though “AL3”) indicates an alarm screen. “SIG” appears in place of the alarm number when the Hourly Time Signal screen is shown.

All of the operations in this section are performed in the Alarm Mode, which you enter by pressing C (page

E-4).

Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receive indicator to indicate signal strength.

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

The receive indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The receive indicator does not appear if signal reception was unsuccessful or after manual adjustment of the current time setting.

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the digital time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM, and 6:00 AM each day (calibration times).

Note

The Auto Receive operation is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if the calibration time is reached while you are making settings (while settings are flashing on the display).

Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the digital 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 easily receive the signal.

The receive indicator ( ) indicates that one, two, or all three of the last calibration time reception attempts were successful.

When auto receive is turned on, the watch receives the calibration signal for four to 11 minutes each day when the digital time reaches 2:00 AM, 4:00 AM, and 6:00 AM. Do not operate any of the watch’s buttons within 15 minutes prior to or following the calibration times. Doing so can interfere with correct calibration.

Remember that reception of the calibration signal depends on the time shown on the digital display. The receive operation will be performed whenever the digital display shows 2:00 AM, 4:00 AM, and 6:00 AM, regardless of whether or not the displayed time is actually the correct time.

When two or three receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.

1. In the Timekeeping Mode, hold down A until the current Auto Receive On/Off setting starts to flash, which indicates the setting screen.
