Operation Guide 3150
Note
To turn auto receive on and off
•When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.
•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). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.
•The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven minutes before or after 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.

2.Hold down A until the current auto receive setting (ON or OFF) starts to flash. This is the setting screen.
•Note that the setting screen will not appear if the currently selected Home City is one that does not support time calibration reception.
3.Press D to toggle auto receive on (ON) and off (OFF).4.Press A to exit the setting screen.•For information about city codes that support signal receive, see “To specify your Home City”.
About the Signal Strength Indicator
The signal strength 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 signal strength indicator is displayed while an auto or manual receive operation is in progress.

(Level 1) | (Level 3) |
•Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the signal strength indicator to indicate signal strength.
•Use the signal strength indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.
•Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 3 signal strength indicator will remain on the display in all modes. The Level 3 signal strength indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.
•The Level 3 signal strength indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.
•The Level 3 signal strength indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 signal strength indicator disappears from the display each day when the first auto receive operation of the day is performed.
