Timekeeping is kept accurate using information provided by a time calibration signal and by

communication with a mobile phone.

x Time calibration signals can be received using Auto Receive or Manual Receive (page E-11).

x To set the current time and day, normally use the procedure under “Time Calibration Signal Auto

Receive” (page E-12).

x For information about how to adjust time using a phone, refer to the Operation Guide available at

the website below.

https://world.casio.com/manual/wat/

x Time calibration signal auto receive is not performed while the watch is able to connect with a

phone to adjust the watch time setting. Signal reception is performed whenever the watch is

unable to connect with a phone for time adjustment for more than one day.

x If you are in an area where a time calibration signal cannot be received or if you cannot connect

with a phone for some reason, adjust time and date settings manually (page E-16).

Important!

x 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 time zone where you are using the watch (pages

E-14 and L-2).

x If you feel that the current time and/or day indicator are not in the correct positions, you can adjust

their alignment. For details, see the Operation Guide available at the CASIO website.

x Time calibration signal reception is normally possible in the areas below.
