Auto Time Calibration Signal Receive

An automatic time calibration signal receive operation is performed and the time and day settings are adjusted between midnight and 5:00 a.m. Once a signal receive operation is successful, no more auto receive operations are performed that day.

  1. Place the watch near a window or some other location appropriate for signal reception.

  2. [RC !] is shown on the display while time signal reception is in progress.

    When a receive operation is successful, the watch adjusts its current time and day settings automatically, and then returns to the Timekeeping Mode.


Reception takes anywhere from about two minutes to about 10 minutes. It can take as long as 20 minutes.
