Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal and update its time setting

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.
Before performing a signal receive operation, remove the watch from you wrist and
position it as shown in the illustrations below.
