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 Time Zone, and whether Standard Time or Daylight Saving Time is selected for your Time Zone.
Note
•Auto receive is turned on whenever +0, +1, or +2 is selected as the Home Time Zone.

Note
• Auto receive works only while the watch is in the Timekeeping Mode. Auto receive is |
not performed if an auto receive time is reached while an alarm is sounding, or if a |
setting screen (a screen with a flashing setting) is on the display. |
• 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). |

When the alarm is turned on, the alarm sounds when the alarm time is reached. You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the hour.
•All of the operations in this section are performed in the Alarm Mode, which you enter by pressing C.
Before going to bed for the night, remove the watch from your wrist, and put it in a |

Alarm on
Hourly time signal on indicator
• When auto receive is turned on, the watch receives the calibration signal for two to |
14 minutes everyday when the time in the Timekeeping Mode reaches each of the |
calibration times. Avoid performing any button operation within 14 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. The receiving indicator is displayed while an auto or manual receive operation is in progress.
