Operation Guide 3070
• The watch receives the calibration signal for two to seven minutes everyday |
when the time in the Timekeeping Mode reaches each of the calibration |
times. Do not perform any button operation within seven 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. |
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.

•Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.
•Use the receiving 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 5 receiving indicator will remain on the display in all modes. The Level 5 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.
•The Level 5 receiving 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 5 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 5 receiving indicator disappears from the display each day when the first auto receive operation of the day is performed.
