Module No. 5682
The watch’s time and day settings can be configured in accordance with a received time calibration signal.
In order to make it possible for the current time setting to be adjusted correctly based on time calibration signal reception, you need to specify the area where you are using the watch.
Areas where time signal reception is supported are limited. When you are using the watch in an area where time calibration signal reception is not possible, adjust time and day settings manually.
