Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal and update its time setting in accordance with the signal. There are two different methods you can use to receive the signal: Auto Receive and Manual Receive. With Auto Receive, the watch automatically receives the calibration signal three times each day and makes appropriate adjustments. With Manual Receive, you perform a specific button operation to receive the calibration signal.
