Casio 3069 Watch User Manual


 
E-22
Note
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 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.
