Whenever you are in a hospital, on an aircraft, or in any other location where connection with a phone may cause problems, you can perform the procedure below to disable auto time adjustment. 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.

When a connection is established between the watch and phone, [APP] will change to [OK], and the second hand will move from [R] to [C].

• If connection fails for some reason, [ERR] will appear on the display momentarily and then the watch will return to the mode it was in before you started the connection procedure.

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