Operation Guide 4756
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).
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.
• When auto receive is turned on, the watch receives the calibration signal for four to
seven minutes everyday when the time in the Timekeeping Mode reaches each of
the calibration times. Avoid performing 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.
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.
