You can use CASIO WATCHES to specify the amount of time until the Bluetooth connection is automatically terminated, and to configure other watch settings.

1. Tap the “CASIO WATCHES” icon.

2. Hold down (A) for at least 2.5 seconds. Release the button when the second hand moves to [C].

This establishes a connection between the watch and phone.

3. Select the setting you want to change and then perform the operation shown on the phone screen.
