You can use the procedure below to disable auto time adjustment when you are in a hospital, inside an aircraft, or in any other area where use of a phone is prohibited or restricted. To re-enable auto time adjustment, perform the same operation again.

1. Tap the “CASIO WATCHES” icon.

2. Hold down (B) for at least two seconds until the second hand points to [R] twice.

This establishes a connection between the watch and phone.

3. Perform the operation shown on the phone screen to enable or disable auto time adjustment.
